Autores: ALVES, F. S. F.; LEFEBVRE, R. B.; PROBERT, W.
This report describes a partial amino acid sequences from three putative outer envelope proteins from Leptospira serovar pomona. In order to obtain internal fragments for protein sequencing, enzymatic and chemical digestion was performed. The enzyme clostripain was used to digest the proteins 32 and 45kDa. In situ digestion of 40kDa molecular weight protein was accomplished using cyanogen bromide. The 32kDa protein generated two fragments, one of 21kDa and another of 10kDa that yielded five residues. A fragment of 24 kDa that yielded nineteen residues of amino acids was obtained from 45 kDa protein. A fragment with a molecular weight of 20 kDa, yielding a twenty amino acids sequence from the 40kDa protein.

Dietary zinc (Zn) deficiency is widespread globally, and is particularly prevalent in low- and middle-income countries (LMICs). Cowpea (Vigna unguiculata (L.) Walp) is consumed widely in LMICs due to its high protein content, and has potential for use in agronomic biofortification strategies using Zn. This study aimed to evaluate the effect of Zn biofortification on grain nutritional quality of 29 cowpea genotypes. Zn application did not increase cowpea yield. In 11 genotypes sucrose concentration, in 12 genotypes total sugar concentration, and in 27 genotypes storage protein concentration increased in response to Zn supply. Fifteen genotypes had lower concentrations of amino acids under Zn application, which are likely to have been converted into storage...

Autores: OLIVEIRA, M. E. A. S.; BASSINELLO, P. Z.; COLOMBARI FILHO, J. M.; CARVALHO, C. W. P. de; TAKEITI, C. Y.
In this work, the impact of germination and debranning on the total (TAA) and free (FAA) amino acid in four rice cultivars were evaluated. The rice genotypes were germinated, polished and analyzed by the content of TAA and FAA. In comparison to non-germinated rice, 4 h of soaking and 24 h of germination increased the level of TAA and FAA, especially y-aminobutyric acid (GABA). Debranning decreased the content of TAA and FAA. But, even after this reduction, the polished germinated samples showed higher levels of TAA and FAA than the polished non-germinated.The significant impact on the amino acid composition was caused mainly by genotype than the process used. These results could help the food industry to produce germinated rice enriched with high amino...

The nutritional requirements of A. brasiliensis in culture media were assessed by supplementing a basal medium (g L-1): (glucose, 10, KH2PO4, 1, MgSO4.7H2O, 0.5, [NH4]2SO4, 1, pH 5.5) with CaCl2, trace elements (FeSO4.7H2O; MnCl2.4H2O; ZnSO4.7H2O; CuSO4.5H2O), casein, yeast extract, peptone, B-vitamins or amino acids. Evaluations were based on the mycelial growth in solid or liquid culture (mm day-1 or mg day-1) and visual analysis of the colony. The addition of CaCl2 and trace elements was very important for the major mycelial growth of the fungi. The addition of casein and inositol to the medium did not have a significant effect on growth. The best growth result in solid medium was obtained with the basal medium plus the addition of yeast extract and...

ABSTRACT The purpose of this study was to develop and improve protein concentration techniques for two industrial by-products with the potential for use in fish feed. In particular, we chemically characterized crambe meal and sunflower meal and their protein concentrates. Three different protein concentration methods were tested: isoelectric pH (pHi), acid pH and alkaline pH. For crambe and sunflower meals extraction using the pHi method was most efficient in terms of protein yield and crude protein content in the concentrates; this method also increased lysine and methionine content in the concentrates. The water holding capacity of the sunflower protein concentrate was greater than that of the crambe protein concentrate. The crambe protein concentrate...

ABSTRACT In this study, we are presenting recommendations to the best agricultural use as well as for plant breeding of three millet cultivars namely ENA1 and ENA2, which have African origin, and BRS1501 originally from India. These cultivars were evaluated for growth, yield and grain quality traits. The morphological traits evaluated in this study indicated that the African genotypes ENA1 and ENA2 are better than the Indian genotype BRS1501 for no-till farming or to produce forage with 15% of crude protein at flowering and at harvest to produce stover (around 7% of crude protein content) for livestock feeding. The BRS1501 cultivar exhibited the highest values for total crude protein, albumins and prolamins, phytate and mineral contents in grains. ENA1 and...

Autores: ALCÂNTARA,BERENICE K.; RIZZI,VANESSA; GAZIOLA,SALETE A.; AZEVEDO,RICARDO A.
ABSTRACT Both the scientific community and society have shown interest in improving the content of amino acids, carbohydrates and mineral nutrients in maize because it represents an important staple food in many developing countries. Earlier studies demonstrated that the treatment of seeds using ascorbic acid (AsA-seed priming) enhanced soluble carbohydrates, proteins and soluble amino acids for other species. AsA seed priming in maize showed the potential for reducing abiotic stresses. The effects on grain quality have not been previously demonstrated. This study investigated the impacts of AsA seed priming on maize kernel quality of seeds produced by the plants generated from the primed seeds, based on the amino acid profile and carbohydrate and mineral...

ABSTRACTThe aim of this work was to investigate whether the free radical scavengers, L-arginine (L-arg) and/or carnosine, either alone, or in combination would modulate tissue injury induced by hypoxia by measuring Fischer's ratio [concentrations of branched chain amino acids (BCAAs)/aromatic amino acids]. Decreased Fischer's ratios and increased malondialdehyde (MDA) led to pathogeneses of many diseases. Rats were injected with sodium nitrite (60 mg/kg) to establish hypoxia. They were treated with L-arg, (200 mg/ kg) and/or carnosine (200 mg/ kg) and their combination 24 and 1 h prior to sodium nitrite intoxication. The results revealed that hypoxia significantly decreased hemoglobin, arginine, citrulline and proline and increased sLDH, MDA , ammonia ,...

Alterations in proteins and amino acids of the Nile cyanobacteria Pseudanabaena limnetica and Anabaena wisconsinense in response to industrial wastewater pollution
Provedor de dados: 52
Autores: El-Sheekh,Mostafa Mohamed; El-Otify,Ahmed Mohamed; Saber,Hani.
The effect of industrial wastewater on the Nile cyanobacteria Pseudanabaena limnetica and Anabaena wisconsinense was investigated. The data showed that P. limnetica was more sensitive to pollution than A. wisconsinense. The treatments with different levels of wastewater exerted pronounced reductions in protein and amino acids content. SDS-PAGE analysis revealed that the cyanobacteria grown in the industrial wastewater showed induction in the synthesis of certain polypeptides and repression of others. The treatments of P. limnetica with wastewater stimulated the appearance of six protein bands with molecular masses of 28, 30, 31, 32, 58 and 97 kDa. The same treatments caused the disappearance of 20, 38 and 56 kDa. The structural protein pattern of the...

Provedor de dados: 52
Autores: Shimizu,Milton Massao; Mazzafera,Paulo.
Endosperm is the main reserve tissue in coffee seeds. Coffee (Coffea arabica L.) seeds were germinated for six weeks and qualitative and quantitative changes in amino acids and proteins were investigated. The total content of free amino acids were reduced during germination, however, protein content remained constant. SDS-PAGE profiles showed that legumin-like proteins became less stained in the last weeks. Asparagine, glutamic acid, aspartic acid, alanine and lysine were the major free amino acids, although serine and glutamine were also significant. Except for tyrosine, which increased with germination, all other amino acids were reduced. Analysis of the amino acid composition of the total soluble protein showed glutamic acid/glutamine and glycine as the...

Are high-lysine cereal crops still a challenge?
Provedor de dados: 56
Autores: Ferreira,R.R.; Varisi,V.A.; Meinhardt,L.W.; Lea,P.J.; Azevedo,R.A.
The essential amino acids lysine and threonine are synthesized in higher plants via a pathway starting with aspartate that also leads to the formation of methionine and isoleucine. Lysine is one of most limiting amino acids in plants consumed by humans and livestock. Recent genetic, molecular, and biochemical evidence suggests that lysine synthesis and catabolism are regulated by complex mechanisms. Early kinetic studies utilizing mutants and transgenic plants that over-accumulate lysine have indicated that the major step for the regulation of lysine biosynthesis is at the enzyme dihydrodipicolinate synthase. Despite this tight regulation, recent strong evidence indicates that lysine catabolism is also subject to control, particularly in cereal seeds. The...

Autores: Carvalho,D.P.; Ferreira,A.C.F.; Coelho,S.M.; Moraes,J.M.; Camacho,M.A.S.; Rosenthal,D.
Normal in vitro thyroid peroxidase (TPO) iodide oxidation activity was completely inhibited by a hydrolyzed TPO preparation (0.15 mg/ml) or hydrolyzed bovine serum albumin (BSA, 0.2 mg/ml). A pancreatic hydrolysate of casein (trypticase peptone, 0.1 mg/ml) and some amino acids (cysteine, tryptophan and methionine, 50 µM each) also inhibited the TPO iodide oxidation reaction completely, whereas casamino acids (0.1 mg/ml), and tyrosine, phenylalanine and histidine (50 µM each) inhibited the TPO reaction by 54% or less. A pancreatic digest of gelatin (0.1 mg/ml) or any other amino acid (50 µM) tested did not significantly decrease TPO activity. The amino acids that impair iodide oxidation also inhibit the TPO albumin iodination activity. The inhibitory amino...

Provedor de dados: 56
Autores: Oliveira,I.C.; Brenner,E.; Chiu,J.; Hsieh,M.-H.; Kouranov,A.; Lam,H.-M.; Shin,M.J.; Coruzzi,G.
We are using molecular, biochemical, and genetic approaches to study the structural and regulatory genes controlling the assimilation of inorganic nitrogen into the amino acids glutamine, glutamate, aspartate and asparagine. These amino acids serve as the principal nitrogen-transport amino acids in most crop and higher plants including Arabidopsis thaliana. We have begun to investigate the regulatory mechanisms controlling nitrogen assimilation into these amino acids in plants using molecular and genetic approaches in Arabidopsis. The synthesis of the amide amino acids glutamine and asparagine is subject to tight regulation in response to environmental factors such as light and to metabolic factors such as sucrose and amino acids. For instance, light...

Provedor de dados: 56
Autores: Gomes-Marcondes,M.C.C.; Honma,H.N.; Areas,M.A.; Cury,L.
In tumor-bearing rats, most of the serum amino acids are used for synthesis and oxidation processes by the neoplastic tissue. In the present study, the effect of Walker 256 carcinoma growth on the intestinal absorption of leucine, methionine and glucose was investigated in newly weaned and mature rats. Food intake and carcass weight were decreased in newly weaned (NT) and mature (MT) rats bearing Walker 256 tumor in comparison with control animals (NC and MC). The tumor/carcass weight ratio was higher in NT than in MT rats, whereas nitrogen balance was significantly decreased in both as compared to control animals. Glucose absorption was significantly reduced in MT rats (MT = 47.3 ± 4.9 vs MC = 99.8 ± 5.3 nmol min-1 cm-1, Kruskal-Wallis test,...

Autores: Tiwari,F.; Singh,D.K.
Adult Lymnaea acuminata (average length 20-22 mm) were collected locally from lakes and low-lying submerged fields from Gorakhpur. The chemoattraction studies were made in round glass aquaria measuring 30 cm in diameter and filled to a depth of 10 mm with 500 ml dechlorinated tap water. Each aquarium was divided into four concentric zones. At the starting time of the assay 10 snails were placed on the circumference of outermost zone 0. Snail attractant pellets (SAP) were added simultaneously in the center of central zone 3. SAP of different amino acids were prepared at concentrations of 10, 20, 50, 80 and 100 mM/2% agar solution and, subsequently, spread to a uniform thickness of 5 mm. After cooling, SAP were cut in small pieces of 5 mm in diameter....

Effects of monosulfuron-ester on metabolic processes of nitrogen-fixing cyanobacteria Anabaena flos-aquae and Anabaena azotica
Provedor de dados: 58
Autores: Shen,Jian Ying; Liao,Jin Zhi; Guo,Li Li; Su,Rui Fang.
Abstract Presence of the relatively new sulfonylurea herbicide monosulfuron-ester at 0.03-300 nmol/L affected the growth of two non-target nitrogen-fixing cyanobacteria (Anabaena flos-aquae and Anabaena azotica) and substantially inhibited in vitro Acetolactate synthase activity, with IC50 of 3.3 and 101.3 nmol/L for A. flos-aquae and A. azotica, respectively. Presenting in 30-300 nmol/L, it inhibited protein synthesis of the cyanobacteria with less amino acids produced as its concentration increased. Our findings support the view that monosulfuron-ester toxicity in both nitrogen-fixing cyanobacteria is due to its interference with protein metabolism via inhibition of branch-chain amino acid biosynthesis, and particularly Acetolactate synthase activity.

Autores: Pinotti,T.; Carvalho,P.M.B.; Garcia,K.M.G.; Silva,T.R.; Hagler,Allen Norton; Leite,S.G.F.
The ability of Geotrichum candidum to produce fruity aroma in food grade sucrose, molasses, corn steep liquor and peptone based culture media was tested by sensory evaluation and analyzed by gas chromatography mass spectrometry. A strong and sweet fruity aroma was produced from molasses, with peptone or corn steep liquor stimulating aroma production. Molasses with peptone supplemented with leucine, valine, or alanine yielded better fruity aroma production and the presence of many esters was consistent with the fruity aroma production.

Lysine catabolism: flow, metabolic role and regulation
Provedor de dados: 61
Autores: Fornazier,Ricardo Francisco; Azevedo,Ricardo Antunes; Ferreira,Renato Rodrigues; Varisi,Vanderlei Aparecido.
Lysine is an essential amino acid, synthesized in plants in the aspartic acid pathway. The lysine catabolism is performed by the action of two consecutive enzymes, lysine 2-oxoglutarate reductase (LOR) and saccharopine dehydrogenase (SDH). The steady state of lysine is controlled by both, synthesis and catabolism rates, with the final soluble lysine concentration in cereal seeds a direct result of these processes. In the last 40 years, the enzymes involved in lysine biosynthesis have been purified and characterized from some plant species such as carrot, maize, barley, rice, and coix. Recent reports have revealed that lysine degradation might be related to various physiological processes, for instance growth, development and response to environmental...

Isolation of enzymes involved in threonine biosynthesis from sorghum seeds
Provedor de dados: 61
Autores: Ferreira,Renato Rodrigues; Vendemiatti,Ariane; Meinhardt,Lyndel Wayne; Lea,Peter John; Azevedo,Ricardo Antunes.
Cereal seeds are poor in essential amino acids, particularly lysine, tryptophan and threonine. The amino acids lysine and threonine are synthesized in the aspartate pathway. Although most of the enzymes of the aspartate pathway have been isolated and characterized in higher plant species, the metabolism of lysine and threonine is totally unknown in sorghum. We have isolated two enzymes, aspartate kinase (AK) and homoserine dehydrogenase (HSDH) from sorghum. Optimum assay conditions were established for the determination of AK and HSDH activities. The highest level of activity was observed in immature seeds. AK was shown to be inhibited by threonine and lysine indicating the existence of at least two isoenzymes, one sensitive to threonine inhibition and the...

Abstract  Food-type soybean, considered a functional and nutritious food, becomes an new alternative food in human nutrition, and its preserve is an option to the consumer market. The present study aims to verify the effect of maceration time of the grains and the acetic acid concentration in brine on the physical and chemical characteristics of a edible soybean preserves, and to evaluate the proximal composition, microbiological risk and sensory acceptance of the selected preserve. The methodology used was the response surface and the central composite rotational design. The presence of acetic acid in the brine was prejudicial to the quality of the edible soybean preserve - BRSMG 790A cultivar. The soybean preserve with the best characteristics was...

ABSTRACT: Response surface methodology was used to determine optimum conditions for extraction of protein from pumpkin seed meal. A central composite rotational design (CCRD) including independent variables such, pH and sodium trimetaphosphate (STMP) content was used. Maximum yield was obtained at a central point of CCRD, with STMP content and pH of 4% and 4.5, respectively. These conditions resulted in protein yield of 50.04 g of soluble protein from extract/100 g pumpkin seed. The optimization of pH and STMP content allowed obtaining a product with a high protein concentration (62.56 g 100 g-1), digestibility (62.03 g 100 g-1) and concentration of essential amino acids (27.26 g 100 g-1). Regarding the polyphenols concentration, phosphorylated protein...

Autores: Pastore,Silvana Marques; Albino,Luiz Fernando Teixeira; Gomes,Paulo Cezar; Oliveira,Will Pereira de; Viana,Gabriel da Silva; Silva,Eliane Aparecida da; Alves,Warley Junior.
ABSTRACT: This trial was performed to determine the dietary digestible threonine-to-lysine (dig. Thr-to-Lys) ideal ratio for laying hens fed with low-protein diets from 24 to 40 weeks of age. At 24 weeks of age, two hundred forty Hy Line W-36 laying hens were randomly assigned to five treatments, represented by five dig Thr-to-Lys ratios (60; 67; 74; 81 and 88%), with eight replicates each one with six hens per experimental unit. Digestible Thr-to-Lys did not affect laying hen performance and egg quality, except for digestible Threonine intake, which showed linear increase as dig. Thr-to-Lys ratios increased. Linear broken-line model was chosen to analyze data according to lack of fit. According to linear broken-linen estimates, digestible Threonine ideal...

ABSTRACT: The study aimed to evaluate the effects of arginine supplementation in the lactation diet of sows on their milk composition, litter performance and piglet survival. Sixty-four lactating Landrace x Large White sows, parity 1 to 7, were randomly assigned to two treatments: 1) Control - a corn/soybean meal based diet with 1.10% standardized ileal digestible (SID) lysine and 3,475kcal of metabolizable energy (ME) kg-1, and 2) arginine - the control diet top-dressed daily with arginine at 1% of feed allowance. The daily feed allowance per sow was 5.0 and 7.5kg from day (D)0 to D7 and D8 to D21, respectively. The average litter size was 12.8 piglets after cross-fostering. Litters were weighed on D1, D10, and D21 of lactation and pre-weaning mortality...

ABSTRACT: Two experiments were conducted to evaluate the effects of reducing dietary crude protein (CP), based on the ideal protein concept for Nile tilapia reared in net pens. The experimental (isocaloric, isocalcium, and isophosphoric) diets were formulated to contain 270, 300, 330, and 360g kg-1 CP. In experiment 1, 4320 Nile tilapia (13.5±0.82g) were used to evaluate the performance and hematological parameters. The experimental design was completely randomized and the fish were distributed in 24 net pens (1.0m3), with four diets, six replicates, and 180 fishes per experimental unit. In experiment 2, 40 Nile tilapia (22.5±0.56g) were used to evaluate the ammonia excretion. Fish were distributed in 40 aquaria (3.0L), with one fish per aquarium (n=10)....

Sequential use of ammonium and leucine as nitrogen sources during growth of Geotrichum candidum on a glucose based medium
Provedor de dados: 69
Autores: Adour,Lydia; Bude,Florence; Amrane,Abdeltif.
Geotrichum candidum growth on ammonium and leucine as nitrogen sources and glucose as a carbon source was examined. A clear preference of G. candidum for ammonium over leucine as a nitrogen source was shown. Indeed, ammonium was completely exhausted at the end of exponential growth after less than 35 hrs of culture; in contrast only 5% of leucine was concomitantly assimilated. Growth continued at slower rates on glucose and leucine as carbon and nitrogen sources respectively, and at the end of culture (185 hrs), leucine was completely exhausted.

Белки, аминокислоты и углеводы в прибрежных наносах Севастопольской бухты Черного моря
Provedor de dados: 13
Autores: Миронов, О. Г.; Гапонюк, Т. О.; Муравьева, И. П.; Замыслова, Т. Н.
В прибрежных наносах линии уреза северного побережья Севастопольской бухты впервые определено содержание белков, аминокислот и углеводов. Установлено преобладание количества белков над углеводами, в то время как в море в целом преобладают углеводные соединения. Если в целом в Севастопольской бухте наблюдаются сезонные колебания концентрации органических веществ, то в условиях наносов, постоянно омывающихся морской водой, сезонная динамика не наблюдается. Отношение концентрации углеводов к белку в наносах составляет десятые и сотые доли, что в десятки раз ниже, чем в поверхностном слое грунтов как открытого моря, так и бухт. Средняя концентрация белков и углеводов в наносах выше, чем в грунтах того же механического состава.

Особенности реорганизации тканевого метаболизма у двустворчатого моллюска Anadara inaequivalvis (Bruguiere, 1789) в условиях экспериментального голодания
Provedor de dados: 13
Autores: Солдатов, А. А.; Андреенко, Т. И.; Головина, И. В.
В экспериментальных условиях исследовано влияние голодания на направленность метаболических процессов в тканях двустворчатого моллюска-вселенца Anadara inaequivalvis (Bruguiere, 1789). Длительность эксперимента – 18 сут. Показано, что на начальных этапах голодания (6 сут.) анадара использует ресурс тканевого лактата в направлении реакций окислительного декарбоксилирования. Об этом свидетельствует значительный рост активности лактатдегидрогеназы на фоне снижения содержания лактата и повышения уровня пирувата в тканях. Процесс адаптации анадары к голоданию идет по пути использования резерва аминокислот в процессах биосинтеза белка. Это отражает уменьшение уровня аминного азота во всех исследованных тканях и рост содержания белка при отсутствии выраженных...

The nutritional requirements of the Japanese shrimp Penaeus japonicus
Provedor de dados: 5
Autores: Guillaume, Julien.
Penaeus japonicus is probably the best known species among penaeids or even among shrimps. In juveniles, the protein requirement was best studied and Japanese shrimp appears as the most demanding penaeid species. They may be related to several factors such as energy level of the diet, digestibility or biological value of protein or other nutritional factors. The essential amino acids are well known, however from a quantitative point of view the requirements in each of these amino acids remain to be determined.

Définition d'un modèle d'élevage larvaire intensif pour la daurade Sparus auratus
Provedor de dados: 5
Autores: Ounais-guschemann, Nadia.
This study defines rearing parameters for mass products of 30-day old post larvae. Continuous lighting (600 lux) optimizes the predatory activity and suppresses the feeding rhythm. For 4-5 mm larvae (15 days), food ingestion slows down if the prey concentration in the tank is below 5 rotifers/ml, while there is no such threshold for 6-7 mm larvae (22 days). The rotifer Brachionus plicatilis , between 100 and 200 mu m, is an adequate initial prey, it can be replaced by Artemia salina for 7-8 mm larvae (30 days). It is observed that free amino acids and essential fatty acids contents have a prominent role in larvae growth; docosahexaenoic acid (C22:6n-3) content could be determined. Finally, the development of the swim bladder is facilitated by the renewal...

Organic matter in sediments in the mangrove areas and adjacent continental margins of Brazil .1. Amino acids and hexosamines
Provedor de dados: 5
Autores: Jennerjahn, Tc; Ittekkot, V.
The nature of sedimentary organic matter from mangroves and the continental margin of eastern Brazil (8 degrees-24 degrees S) has been investigated in order to obtain information on sources and diagenetic processes. The organic matter content of mangrove sediments is three to four times higher than the maximum content of continental margin sediments. Downslope distribution of organic carbon, nitrogen, amino acids and hexosamines shows an enrichment in water depths between 800 m and 1000 m. The distribution of individual amino acids and hexosamines is highly variable in sedimentary organic matter from mangroves and the continental margin, and the observed compositional differences are mainly due to diagenetic alteration. Organic matter is highly reactive in...

Autores: Guillaume, Julien; Cruz, R; Cuzon, Gerard; Wormhoudt Van, A; Revol, A.
Some nutrients known as non essential in vertebrates could be essential in invertebrates and could be related to some "unknown growth factors" which were evidenced or suspected, mainly in mollusc or crustacean flesh or meal, by several authors working on different species of crustaceans. A set of experiments was carried out in our laboratory in order to isolate one of these factors found in squid meal.

Provedor de dados: 5
Autores: Vanwambeke, F; Bianchi, M.
Bacterial response to organic (amino acids) or inorganic (NH sub(4) super(+)) nitrogen was studied in 350 liter closed batch systems. The experiments demonstrate an important NH sub(4) super(+) remineralization associated with bacterial growth. The differences between substrate and bacterial C/N ratios and bacterial metabolic demands partly explain the high values of ammonia produced. Grazing by heterotrophic microflagellates resulted in an important release of NH sub(4) super(+). This suggests and important role of grazers for the nitrogen remineralization in natural waters.

Autores: Martin-jezequel, Veronique; Calu, Guillaume; Candela, Leo; Amzil, Zouher; Jauffrais, Thierry; Sechet, Veronique; Weigel, Pierre.
Over the last century, human activities have altered the global nitrogen cycle, and anthropogenic inputs of both inorganic and organic nitrogen species have increased around the world, causing significant changes to the functioning of aquatic ecosystems. The increasing frequency of Pseudo-nitzschia spp. in estuarine and coastal waters reinforces the need to understand better the environmental control of its growth and domoic acid (DA) production. Here, we document Pseudo-nitzschia spp. growth and toxicity on a large set of inorganic and organic nitrogen (nitrate, ammonium, urea, glutamate, glutamine, arginine and taurine). Our study focused on two species isolated from European coastal waters: P. multiseries CCL70 and P. australis PNC1. The nitrogen...

The abilities of several biochemical characteristics of sedimentary organic matter to describe quantitative changes in benthic fauna were assessed based on several surveys carried out within the Gulf of Lion during the last decade. Two sets of high frequency samplings were carried out both inshore and offshore, together with an assessment of seasonal variability along a depth gradient, and a synoptic assessment of mesoscale spatial variability. The considered biochemical parameters were: total organic matter, organic carbon, nitrogen, total proteins, available proteins, carbohydrates, lipids, total and available amino acids. The considered faunal parameters were the abundance and the biomass of both meio- and macrofauna. Our results contribute to unravel...

Protein sources in feed for farmed fish
Provedor de dados: 5
Autores: Medale, Francoise; Kaushik, Sadasivam.
Fish require diets containing 30 to 55% of crude protein and an amino acid supply precisely adapted to meeting the needs for optimal growth. Fish meal is an ideal protein source for aquafeed because it has a high protein level (65% to 72%) with an ideal proportion of all ten indispensable amino acids that meet the requirements of all fish species. However, finding alternatives to fish meal has become an absolute necessity in order to reduce the reliance of aquaculture on marine ingredients. Animal by-product meals (meat meal, bone meal, blood meal, poultry by-product meal, hydrolysed feather meal) are used as alternative protein sources in aquafeed in extra-European countries. Since the use of animal protein in aquafeed is forbidden in Europe (except non...

A brief review of nutritional studies for Penaeus monodon
Provedor de dados: 5
Autores: Liao, I; Liu, F.
In order to develop effective formulated for Penaeus monodon , sufficient information is needed on its nutritional requirements. Unfortunately, research on this area has been very limited. This paper outlines the results of such research. Since data on the nutritional requirements of P. japonicus are relatively well established, some of these data are also reviewed in this paper and are used as a basis for assessing the nutritional requirements of P. monodon . Protein, lipid, carbohydrate, mineral and vitamin requirements are evaluated from the parameters of growth survival and feed efficiency. Studies on the effects of enzymes and the development of microparticulate diet for larvae are also summarized.

Release of dissolved amino acids by flagellates and ciliates grazing on bacteria
Provedor de dados: 5
Autores: Ferrier-pages, C; Karner, M; Rassoulzadegan, F.
Release of amino acids was examined in the laboratory in the form of dissolved primary amine (DPA) by two marine planktonic protozoa (the oligotrichous ciliate, Strombidium sulcatum and the aplastidic flagellate Pseudobodo sp.) grazing on bacteria. DPA release rates were high (19-25 x 10(-6) and 1.8-2.3 x 10(-6) mu mol DPA cell(-1) h(-1) for flagellates and ciliates, respectively) during the exponential phase, when the ingestion rates were maximum. Release rates were lower during the other growth phases. The release of DPA accounted for 10 % (flagellates) and 16 % (ciliates) of the total nitrogen ingested. Our data suggest that the release of DPA by protozoa could play an important role in supporting bacterial and consequently autotrophic pico- and...

Autores: Kanazawa, A.
Proteins are indispensable nutrients for growth and maintenance of live of all animals. The optimum protein levels in diets for shrimps are different among the various species. Squid meal is an effective protein source for many penaeids. The effects of dietary protein, lipid, and carbohydrate levels on the growth and survival of larvae of Penaeus japonicus were examined by feeding trials using purified diet with carrageenan as a binder. As a result, the effects of protein levels on growth and survival of P. japonicus larvae varied with dietary carbohydrate levels but not dietary lipid levels.

Provedor de dados: 5
Autores: Dias, Jorge; Gomes, Ef; Kaushi, Sj.
The incorporation of an attractant mixture by substitution of an equivalent amount of basal dietary mixture was studied in terms of feed intake and growth performance in European seabass juveniles (mean initial weight : 17 g) fed plant-protein rich diets during 21 days. Three diets had as main protein sources; fish meal, or one of two soy protein concentrates (S and E). To the basal mixture of these last two diets, as well as to a corn-gluten based diet, an attractant amino acid mixture was added at a 2.5% level. Daily feed intake was measured throughout the experimental period. Feed intake and weight gain were highest in seabass fed the fish meal based diet. In those fed the soy protein concentrate diets, the addition of the attractant mixture improved...

Early weaning of marine fish larvae onto microdiets: Constraints and perspectives
Provedor de dados: 5
Autores: Person, L.
Weaning small sized marine fish larvae at first feeding directly onto compound pellets is still difficult, while good results can be obtained when used in combination with live prey or when a prefeeding period on live prey is provided up to a size of about 2-3 mg. Microdiets are generally well ingested as their acceptability and visual detection may be improved using feeding activators and increasing good perception contrast. In theory, food may be processed to have a correct nutritional balance, selection of high digestible components is very important as larval digestive system is not fully functional during the first 2 or 3 weeks of life.

Evolution of bacterial communities precipitating carbonate, in Mediterranean lagoons water and sediment: Study on experimental conditions.
Provedor de dados: 5
Autores: Castanier, S; Maurin, A; Bianchi, A.
To determine if carbonate precipitation is an active or passive bacterial phenomena, factorial analysis has been realized with 880 strains isolated from different samples of sea water and muds kept in various conditions of incubation. Results show the existence of a strong anti-correlation between carbonate precipitation and amino-acid ammonification. Carbonate precipitation is not a passive phenomena linked with amino-acid ammonification.

Chemical and physical composition of grain-type and food-type soybean for food processing
Provedor de dados: 86
Autores: Silva,Josemeyre Bonifácio da; Carrão-Panizzi,Mercedes Concórdia; Prudêncio,Sandra Helena.
The objective of this work was to evaluate the chemical and physical characteristics of grains of soybean (Glycine max) cultivars for food processing. The soybean cultivars evaluated were: grain-type - BRS 133 and BRS 258; food-type - BRS 213 (null lipoxygenases), BRS 267 (vegetable-type) and BRS 216 (small grain size). BRS 267 and BRS 216 cultivars showed higher protein content, indicating that they could promote superior nutritional value. BRS 213 cultivar showed the lowest lipoxygenase activity, and BRS 267, the lowest hexanal content. These characteristics can improve soyfood flavor. After cooking, BRS 267 cultivar grains presented a higher content of aglycones (more biologically active form of isoflavones) and oleic acid, which makes it proper for...

ABSTRACT: Ryegrass(Lolium multiflorum)is one of the most worrisome species with regard to herbicide resistance. This study aimed at characterizing the acetolactate synthase (ALS) enzyme activity of resistant biotypes (NC and AR) and susceptible biotypes to iodosulfuron-methyl-sodium (iodosulfuron). Different concentrations of pyruvate (1, 10, 20, 40, 60, 80 and 100 mM), of iodosulfuron (0 to 100 µM for the resistant biotypes and 0 to 0.5 µM for the susceptible biotype) and concentrations of valine, leucine and isoleucine (0, 0.001, 0.01, 0.1, 1, 10 and 100 mM) were used for the in vitro characterization. According to the results, the Michaelis constant (Km) values (pyruvate) for the assessed biotypes were similar. With iodosulfuron, resistant biotypes...

Fruits were collected from trees of Coffea arabica cv. Obatã grown at Mococa and Adamantina in São Paulo State, Brazil, which are regions with marked differences in air temperature that produce coffee with distinct qualities. Mococa is a cooler location that produces high-quality coffee, whereas coffee from Adamantina is of lower quality. The amino acid and protein contents, amino acid profile, and proteinase activity and type in endosperm protein extracts were analysed. Proteinase genes were identified, and their expression was assayed. All results indicate that temperature plays a role in controlling proteinase activity in coffee endosperm. Proteinase activity was higher in the endosperm of immature fruits from Adamantina, which was correlated with...

Provedor de dados: 89
Autores: Castro,MR; Pinheiro,SRF; Oliveira,RG; Abreu,LRA; Mota,LFM; Miranda,JA.
ABSTRACT Three experiments were conducted to estimate the optimal digestible threonine to lysine ratios (Thr:Lys) of meat-type quails during the pre-starter (1 to 7 days), starter (8 to 14 days) and grower I (15 to 21 days) phases. In each experiment, 600 birds were distributed according to a completely randomized experimental design into five treatments, consisting of five dietary Thr:Lys ratios (0.66, 0.71, 0.76, 0.81 and 0.86%), with eight replicates of 15 quails each. Performance parameters and intestinal morphology were evaluated. During the pre-starter phase, feed intake, threonine intake, weight gain, and ileal villus height linearly increased (p&lt;0.01) as dietary digestible Thr:Lys increased. During the starter phase, increasing digestible...

Effects of lysine levels of diets formulated based on total or digestible amino acids on broiler carcass composition
Provedor de dados: 89
Autores: Nasr,J; Kheiri,F.
The study was conducted to evaluate carcass yield and chemical composition of thigh and breast muscles of broilers fed three different lysine requirement levels: high lysine (+10% NRC), standard (NRC) and low lysine (-10% NRC) and two ways of expressing amino acids in feedstuffs (total or digestible amino acids). The results of this study showed that diet formulation based on digestible amino acids significantly influenced breast yield and abdominal fat deposition. The study showed that increasing lysine level (+10% NRC) of diet significantly increased both carcass and breast percentage and also carcass, breast and thigh weight. The interaction between digestible amino acids and lysine requirement levels affected carcass and breast percentage. Feeding...

Amino acid content of soybean samples collected in different Brazilian states: harvest 2003/2004
Provedor de dados: 89
Autores: Goldflus,F; Ceccantini,M; Santos,W.
Soybean is the most important protein source in animal nutrition and is widely used in poultry diets. Several factors influence the concentration of amino acids present in soybean grains cultivated in Brazil, such as climatic changes, genetics, topography, and soil fertility. Many technologies of soybean processing are used in order to eliminate or inactivate both heat-labile and heat-stable anti-nutritional factors. During processing, soybean by-products with different nutritional values are also produced. Processing conditions may as well affect the coefficients of digestibility of nutrients that are present in soybean protein sources. Furthermore, positive and negative effects of the environment may be masked by changes in processing conditions. This...

Autores: AMARAL,JOSÉ A.T.; DA MATTA,FÁBIO M.; RENA,ALEMAR B.
Active vegetative and reproductive growth in field-grown trees of Coffea arabica L. in Viçosa (20º45’S, 650 m altitude), south-eastern Brazil, occur concurrently. The overall patterns of branch growth and leaf area gain were to a certain extent altered by fruit removal, with growth rates being remarkably greater in de-fruited trees. The content of N-NO3 was not affected by fruiting, whilst that of amino-N was greater in de-fruited than fruiting trees most of the time, but the differences were not large enough to have significantly contributed to the increased growth rates in de-fruited trees. Leaf nitrate reductase activity was greater in plants bearing fruit than in non-bearing ones most of the time; activity was roughly inversely associated with growth....

Autores: Hanigan,Mark D.; White,Robin R.; Apelo,Sebastian I. Arriola; Aguilar,Michelle; Estes,Kari A.; Myers,Adelyn.
ABSTRACT Sustainable production of adequate quantities of food to support a growing human population is a worldwide goal. Under current feeding conditions in the United States, dairy cattle convert dietary nitrogen to milk nitrogen with 25% efficiency. The remaining 75% is excreted, which contributes to air and water quality problems and reduces economic performance of the industry. Efficiency could be improved to 29% if protein was given to just meet current NRC requirements. Additional improvements may be achievable, but only with improved knowledge of amino acid (AA) requirements. The current metabolizable protein requirement model overestimates true requirements due to lack of knowledge of AA supply and requirements and to intrinsic limitations in...

Nutritional innovations on amino acids supplementation in Nile tilapia diets
Provedor de dados: 96
Autores: Furuya,Wilson Massamitu; Furuya,Valéria Rossetto Barriviera.
The optimal dietary supply of amino acids to tilapia has been studied for many years. Nevertheless, a general agreement on the amino acid requirement for tilapias has not been established. In order to optimize efficiency and reduce surplus nitrogen, values of digestibility of each amino acid of feed must be considered. Due to variations in the amino acid requirement due to new tilapia strains introduction, continuous research on amino acid requirements is necessary to elaborate economical and environmental sustainability diets, also improving fish growth, efficiency and fillet yield. The concept of ideal protein in tilapia diets was introduced more than ten years ago, and new researches have shown the importance of protein and amino acids on fish...

Amino acid digestibility and poultry feed formulation: expression, limitations and application
Provedor de dados: 96
Autores: Bryden,Wayne L.; Li,Xiuhua.
The nutritional value or quality of dietary proteins used for poultry feed formulation varies: amino acid availability is an important measure of protein quality. Determination of ileal digestibility values has become the preferred method for estimating amino acid availability. This review discusses the different approaches to the expression of digestibility results, including correction for endogenous loss and the derivatisation of standardised values. Sources of variation in values include, the assay protocol, anti-nutritional factors in feedstuffs and feed milling. Feed formulating with ileal digestibility values should allow higher dietary inclusion levels of protein feedstuffs of lower quality provided that values of different feedstuffs are additive,...

Autores: Isola,Renan Di Giovanni; Hauschild,Luciano; Perondi,Dani; Andretta,Ines; Gobi,Jaqueline de Paula; Remus,Aline; Veira,Alini Mari.
ABSTRACT A nitrogen balance test was performed to evaluate the individual responses of growing pigs to threonine intake. Eight commercial barrows were used (body weight ranging from 15 to 20 kg). A dose-response study was performed, in which the threonine supply increased in seven equidistant steps (the seven dietary threonine levels ranged from 50 to 120% of the requirements) every three days for each pig. The levels of all other amino acids were 20% higher than the tested amino acid. Nitrogen retention as a function of threonine intake was calculated per individual and per group (NLIN and NLMixed, respectively) using a linear plateau model. The highest break point value was 42.42 g of threonine intake (the most demanding individual), whereas the lowest...

Recent advances in sow nutrition
Provedor de dados: 96
Autores: Kim,Sung Woo.
Sows produce a larger number of fetuses than before and these fetuses possess genetic potentials to grow faster than before. Recent comparison shows that a porcine fetus is 40% heavier than 40 years ago. Thus the nutritional management of sows has been updated to reflect these genetic changes. Our recent study quantified nutritional needs for sows to support the growth of fetuses and mammary glands during gestation. Amino acid needs for fetal growth and mammary growth during late gestation (d 70 to farrowing) significantly greater than those needs during early gestation (until d 70). Considering these increases, daily requirement of true ileal digestible Lys for a primiparous sows increases from 7 g (until d 70) to 15 g (d 70 to farrowing). Required...

Two experiments were carried out to evaluate, respectively, nitrogen balance (NB) and the productive performance of 31-to-50-day-old rabbits subjected to different levels of lysine and methionine+cystine (met+cys). Seventy-five animals were randomly distributed in 5 × 3 blocks (five levels of lysine: 5.5, 6.5, 7.5, 8.5 and 9.5 g/kg combined with three levels of met+cys: 5.0, 6.0 and 7.0 g/kg), with 15 treatments and five replications for the NB assay. The assay lasted 14 days: 10 days for acclimatization and four days for feces and urine collection. Increasing met+cys levels had a quadratic effect on the nitrogen excreted in urine (NU): the lowest excretion was found at the dietary level of 5.9 g/kg met+cys. Increasing lysine levels also affected NU and...

Xylem sap nitrogen compounds of some Crotalaria species
Provedor de dados: 63
Autores: Vitória,Angela Pierre; Sodek,Ladaslav.
Thirteen species of Crotalaria were analysed for nitrogen compounds in the xylem root bleeding sap. Amino acids were the main form of organic nitrogen found, but only traces of ureides were present. Of the four species analysed for amino acid composition, asparagine was found to be the major amino acid, accounting for over 68% of the nitrogen transported. No striking deviations from this general pattern was found between species, between vegetative and floral stages of development, or between nodulated and non-nodulated plants. It was concluded that the Crotalaria species studied here have an asparagine-based nitrogen metabolism, consistent with many other non-ureide-producing legume species.

Development of maize (Zea mays L.) cultivars with high grain protein and oil concentrations and an appropriate amino acid composition, without losses in grain yield, represents a challenge in breeding programs. The objective of this work was to study the nutritional quality of ten Brazilian maize populations evaluated in three environments. A randomized block design with six replications was used. Ear yield and the concentrations of protein, oil, serine, glutamic acid, alanine, leucine, tyrosine and phenylalanine were evaluated. Individual and combined analyses of variance were performed. Populations diverged for most of the traits. Environmental effects influenced variation for most of the traits, unlike genotype-environment interaction, allowing the...
