Effects of substrates and reaction conditions on production of cyclodextrins using cyclodextrin glucanotransferase from newly isolated Bacillus agaradhaerens KSU-A11
Provedor de dados: 69
Autores: Ibrahim,Abdelnasser S.S; El-Tayeb,Mohamed A; Elbadawi,Yahya B; Al-Salamah,Ali A.
The effects of reaction conditions on cyclodextrins (CDs) production by CGTase from newly isolated Bacillus agaradhaerens KSU-A11 is reported. Among six types of starch tested, potato starch gave highest starch conversion into CDs. In addition, CDs yield was about three fold higher when using gelatinized potato starch in comparison to raw starch. The total CDs production was increased with increasing pH, showing maximum starch conversion at pH 10. Furthermore, the proportion of &amp;#947;-CD was relatively higher under slightly acidic-neutral conditions than at alkaline pH with a maximum proportion of 35.6% at pH 7 compared to 7.6% at pH 10. Maximum starch conversion into CDs was seen at reaction temperature of 55ºC. Lower reaction temperature led to...

Genetic variability for waxy genes in Argentinean bread wheat germplasm
Provedor de dados: 69
Autores: Vanzetti,Leonardo Sebastián; Pflüger,Laura Alicia; Rodríguez-Quijano,Marta; Carrillo,José Maria; Helguera,Marcelo.
Amylose and amylopectin are the two polysaccharides that constitute starch in bread wheat and the enzyme GBSSI (Granule-bound starch synthase I), also known as waxy protein, is responsible for amylose synthesis in storage tissues. Decrease of the amylose content in starch has been associated with the lack of waxy protein(s). In this work, different sets of PCR markers were used to characterize the genetic variability of waxy loci from 103 Argentinean bread wheat cultivars. For the Wx-A1 locus, Wx-A1a and a novel molecular allele designed Wx-A1g were detected. Wx-B1 locus showed three alleles (Wx-B1a, Wx-B1b, Wx-B1e), and Wx-D1 locus showed only the Wx-D1a allele. Novel single-locus allele specific markers for Wx-A1b, Wx-B1b and Wx-D1b null alleles were...

Biodegradation of a blended starch/natural rubber foam biopolymer and rubber gloves by Streptomyces coelicolor CH13
Provedor de dados: 69
Autores: Watcharakul,Sirimaporn; Umsakul,Kamontam; Hodgson,Brian; Chumeka,Wannapa; Tanrattanakul,Varaporn.
Background: The growing problem of environmental pollution caused by synthetic plastics has led to the search for alternative materials such as biodegradable plastics. Of the biopolymers presently under development, starch/natural rubber is one promising alternative. Several species of bacteria and fungi are capable of degrading natural rubber and many can degrade starch. Results: Streptomyces coelicolor CH13 was isolated from soil according to its ability to produce translucent halos on a mineral salts medium, MSM, supplemented with natural rubber and to degrade starch. Scanning electron microscope studies showed that it colonized the surfaces of strips of a new starch/natural rubber biopolymer and rubber gloves and caused degradation by forming holes,...

Expression and activities of pancreatic enzymes in developing sea bass larvae (Dicentrarchus labrax) in relation to intact and hydrolyzed dietary protein; involvement of cholecystokinin
Provedor de dados: 5
Autores: Cahu, Chantal; Ronnestad, I; Grangier, V; Zambonino, Jose-luis.
In order to assess the influence of dietary protein on digestive enzyme expression and cholecystokinin (CCK) content in sea bass larvae, four groups of larvae were fed experimental diets from mouth opening until day 42: three isonitrogenous diets with increasing protein hydrolysate levels (0%, 14% and 46% of crude matter) and one diet incorporating starch. The groups fed high starch or high protein hydrolysate level exhibited the lowest growth. The final weight in these groups was 9.5 and 5.6 mg, respectively, whereas it reached approximately 20.0 mg in the groups fed 0% or 14% protein hydrolysate level. The highest levels of trypsin secretion were observed in larvae fed the lowest protein hydrolysate level. Paradoxically, the groups fed diet containing...

White breads with Yudane dough (Yudane bread) were made from commercial hard flour by the no first fermentation method. Yudane dough was prepared by mixing boiling water and flour at a ratio of 1:1. The dough at 20 and 40% (w/w, flour base) was added to the total bread dough. In the Yudane bread making method, an extended final proof, lower dough gas retention and gassing power, as well as specific loaf volume were observed compared to conventional bread making (control) without Yudane dough. Also, the moisture content of the Yudane breads increased with increasing water absorption for bread making. The total and reducing saccharide and maltose contents in the water-soluble fraction of Yudane bread also increased with the volume of added Yudane dough. The...

Autores: Finger,Fernando Luiz; Endres,Laurício; Mosquim,Paulo Roberto; Puiatti,Mário.
The objective of this work was to determine the early physiological changes throughout shelf life of fresh broccoli (Brassica oleracea L. var. italica) cv. Piracicaba Precoce at 25ºC and relative humidity of 96% in the dark until complete senescence. Head inflorescences showed lack of turgidity and commercial value when weight loss reached up to 5%, coinciding with 48 hour after harvest. Chlorophyll content was stable until 24 hours after harvesting; afterwards, an intense degradation phase took place. At 72 hours, total head yellowing was observed when chlorophyll content dropped to 30% of its initial content. Peroxidase activity increased by 1.4 fold during the first six hours, dropping to its lowest level approximately 24 hours after harvesting....

Echinolaena inflexa (Poir.) Chase is a native C3 grass species with high biomass production and abundance in the cerrado comparable to Melinis minutiflora Beauv., a C4 forage grass of African origin, widespread in the cerrado, displacing some native herbaceous species. These species accumulate mainly starch, differently of Lolium multiflorum Lam. ssp. italicum Beck cv. Lema (ryegrass), a C3 temperate forage grass that accumulates fructans as the major storage carbohydrate in the vegetative tissues. In the present study, we analyzed diurnal variations in the content and composition of non-structural carbohydrates (NSC) in the aerial vegetative parts of the three species. Results showed similarity in water-soluble carbohydrates (WSC) and starch contents...

Assimilate partitioning in leaves of the raffinose-storing herb Lamium album L.: photosynthesis and carbon partitioning throughout the photoperiod
Provedor de dados: 88
Autores: Kochhar,A.; Rees,T. Ap; Pollock,C.J.
Lamium album accumulates starch, sucrose and raffinose-family oligosaccharides (RFO) as the major products of photosynthesis. These products were measured in leaves throughout a sixteen-hour photoperiod and under various irradiance conditions. There was continuous accumulation of sucrose and starch. The rate of gas exchange was higher at 500 µEm² s-1 and 900 µEm²s-1 than at 300 µEm² s-1. The rate of photosynthesis did not decline over the sixteen-hour photoperiod, which suggested that there was no short-term feed back inhibition due to sucrose accumulation in this plant. When the products of photosynthesis were compared at the end of the photoperiod, only sucrose increased in abundance at high irradiance. The RFO pool in leaves was shown to contain...

Assimilate partitioning in leaves of the raffinose-storing herb Lamium album L.: the effects of altering source-sink balance
Provedor de dados: 88
Autores: Kochhar,A.; Rees,T. Ap; Pollock,C.J.
In Lamium album, sucrose and raffinose-family oligosaccharides are the major products of photosynthesis that are stored in leaves. Using gas analysis and 14CO2 feeding, we compared photosynthesis and the partitioning of recently-fixed carbon in plants where sink activity was lowered by excision of flowers and chilling of roots with those where sink activity was not modified. Reduction in sink activity led to a reduction in the maximum rate of photosynthesis, to retention of fixed carbon in source leaves and to the progressive accumulation of raffinose-family oligosaccharides. This ultimately affected the extractable activities of invertase and sucrose phosphate synthase. At the end of the light period, invertase activity was significantly higher in treated...

Storage substances in the androgametogenesis and mature pollen grain of Ilex paraguariensis St. Hil. (Aquifoliaceae)
Provedor de dados: 88
Autores: SANTOS,RINALDO PIRES DOS; MARIATH,JORGE ERNESTO DE ARAUJO.
Storage substances such as starch grains, proteins and lipids were studied during the male gametogenesis and in the mature pollen grain of Ilex paraguariensis St. Hil. (Aquifoliaceae). There are two cycles of amylogenesis and amylolyse. The first cycle lasts until the vacuolated stage when the starch is hydrolyzed and amorphous proteins are stored inside the single vacuole. The next cycle begins after mitosis with the formation of the vegetative and generative cells. At this point, the young vegetative cell stores many starch grains that are bigger than in the first cycle. During the maturation of the male gametophyte, the starch is hydrolyzed and it is absent in the mature pollen grain. Small lipid droplets surround the young generative cell after the...

Effects of fruiting on the growth of Arabica coffee trees as related to carbohydrate and nitrogen status and to nitrate reductase activity
Provedor de dados: 93
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....

In this experiment the chlorophyll and carbohydrate contents of Arachis pintoi were evaluated to verify if the presence of nitrogen in the soil could contribute to the effectiveness of the establishment of this legume. The design was completely randomized, in a 4 × 4 factorial arrangement, with four N rates (0, 40, 80 and 120 kg ha-1) and four irrigation levels (25, 50, 75 and 100% of field capacity), with four replications. The biochemical evaluations of chlorophylls a and b and total chlorophyll and total soluble sugars, sucrose and starch were performed. The highest contents of chlorophyll a and b and total chlorophyll in leaves were found at the dose of 120 kg ha-1. The water regime of 25% of field capacity was responsible for the lowest content of...

Fasted and postprandial response of serum physiological response, hepatic antioxidant abilities and HSP70 expression in Wuchang bream (Megalobrama amblycephala) fed different dietary carbohydrate levels
Provedor de dados: 96
Autores: Zhou,Chuanpeng; Ge,Xianping; Liu,Bo; Xie,Jun; Chen,Ruli.
The effect of dietary carbohydrate (CHO) level on serum physiological response, hepatic antioxidant abilities and heat shock protein 70 (HSP70) expression of Wuchang bream (Megalobrama amblycephala) was studied. Two isonitrogenous (28.56% crude protein) and isolipidic (5.28% crude lipid) diets were formulated to contain 30% or 53% wheat starch. Diets were fed for 90 days to fish in triplicate tanks (28 fish per tank). At the end of feeding trial, significantly higher serum triglyceride level, insulin level, cortisol level, and malondialdehyde (MDA) content were observed in fish fed the 53% CHO diet, while significantly lower serum total protein content, alkaline phosphatase activity, superoxide dismutase activity and total antioxidative capacity were found...

Methodological challenges in carbohydrate analyses
Provedor de dados: 96
Autores: Hall,Mary Beth.
Carbohydrates can provide up to 80% of the dry matter in animal diets, yet their specific evaluation for research and diet formulation is only now becoming a focus in the animal sciences. Partitioning of dietary carbohydrates for nutritional purposes should reflect differences in digestion and fermentation characteristics and effects on animal performance. Key challenges to designating nutritionally important carbohydrate fractions include classifying the carbohydrates in terms of nutritional characteristics, and selecting analytical methods that describe the desired fraction. The relative lack of information on digestion characteristics of various carbohydrates and their interactions with other fractions in diets means that fractions will not soon be...

Maize (Zea mays L.) landraces are an important source of genes for improving commercial germplasm. Today, drought tolerance and grain quality are major challenges in maize cultivation due to climatic changes and population growth. The Maize Research Institute genebank has a drought tolerant collection, which includes 13 landraces (from the former Yugoslavia) and 12 introduced populations (from different countries). These accessions were analyzed for protein, oil, starch and tryptophan contents, in order to identify drought tolerant accessions with high grain quality. Also, simple sequence repeat (SSR) analysis with specific primers for opaque2 recessive allele (o2) was carried out. All analyzed accessions showed high levels of protein. Oil content ranged...

Boron affects the growth and ultrastructure of castor bean plants
Provedor de dados: 63
Autores: Silva,Denis Herisson da; Rossi,Monica Lanzoni; Boaretto,Antonio Enedi; Nogueira,Neusa de Lima; Muraoka,Takashi.
The cultivation of oleaginous plants like the castor bean guarantees employment for agricultural families and can contribute in energy and chemical sectors, especially in the northeastern semi-arid regions of Brazil. Boron (B) deficiency is a widespread nutritional disorder despite the fact that various anthropogenic sources with high B content may increase soil B to toxic levels for plants. The present study was designed to investigate the ultrastructural effects of boron deficiency and toxicity on castor bean plants which were grown under greenhouse condition using plastic containers with 10 L of nutrient solution. Boron treatments comprised: control (no B); 0.27 mg L-1, 5.40 mg L-1 B pots (one plant per pot), tested in a completely randomized design...

Autores: Freitas,Fábio de Oliveira; Martins,Paulo Sodero.
This research studies archaeological samples of maize (Zea mays mays) and cassava (Manihot esculenta), from Januaria, MG, Brazil, for samples between 1010 (for the oldest sample) and 570 years (for the most recent) as estimated through radiocarbon dating. Maize cobs were morphologically analysed by using length, basal and apical diameters, largest diameter, number of rows, number of grains per row, and number of grains per row per length parameters. The maize cob length presented increases through time, allowing an increase on the number of seed per cob, but the size of seeds did not vary significantly. Starch present in the reserve organs of the maize and cassava were analysed morphologically through Scanning Electron Microscopy, and compared to...

Energy embodiment in Brazilian agriculture: an overview of 23 crops
Provedor de dados: 63
Autores: Veiga,João Paulo Soto; Romanelli,Thiago Libório; Gimenez,Leandro Maria; Busato,Patrizia; Milan,Marcos.
The amount of energy required to produce a commodity or to supply a service varies from one production system to another and consequently giving rise to differing levels of environmental efficiency. Moreover, since energy prices have been continuously increasing over time, this energy amount may be a factor that has economic worth. Biomass production has a variety of end-products such as food, energy, and fiber; thus, taking into account the similarity in end-product of different crops (e.g.: sunflower, peanuts, or soybean for oil) it is possible to evaluate which crops require less energy per functional unit, such as starch, oil, and protein. This information can be used in decision-making about policies for food safety or bioenergy. In this study, 23...

Several Thai traditional starch-based foods use alkali treatment to improve their quality and characteristics. However, limited information is available on how alkali changes the product quality. Therefore, the objective of this research was to investigate the effect of alkali treatment on appearance and texture of cooked glutinous rice. Glutinous rice kernels were soaked in 1N sodium carbonate (Na2CO3) or potassium hydroxide (KOH) for 24 h at room temperature. Sample soaked in water was used as a control. Cooked alkali treated glutinous rice had more yellow color and lower gelatinization temperature than the control. Moreover, they also had lower hardness and stickiness than the control (P&lt; 0.05). KOH had more pronounce effect than Na2CO3. The...

Provedor de dados: 39
Autores: Bicalho,Elisa Monteze; Motoike,Sérgio Yoshimitsu; Lima e Borges,Eduardo Euclydes de; Ataíde,Glauciana da Mata; Guimarães,Valéria Monteze.
ABSTRACT Reserve mobilization in seeds occurs after visible germination, which is marked by the protrusion of the radicle or cotyledonary petiole, as in species of Arecaceae. Acrocomia aculeata (macaw palm), usually produces hard seeds whose endosperm has mannan-rich cell walls. We investigated the composition of storage compounds in macaw palm seed and the roles of two enzymes (endo-β-mannanase, α-galactosidase) during and after germination. The seeds were firstly submitted to pre-established protocol to overcome dormancy and promote germination. Enzyme activity in both embryo and endosperm were assayed from the initiation of germinative activities until leaf sheath appearance, and the status of seed structures and reserve compounds were evaluated....

Autores: Hernández,Marcelo Paulo; Katinas,Liliana; Arambarri,Ana María.
In this paper we examine lipophilic substances, tannins, proteins, reducing carbohydrates, starch, and oxalate salts in early lineages of Asteraceae to test if they are a useful complement to classification studies. Styles of mature flowers of 44 species were processed according to plant histochemical techniques and observed by means of a light microscope. Lipophilic compounds were always present in the cuticle and cell walls, and in some species were located inside the cells. Proteins were located in the style cell walls and cell interior of most of the analyzed species. No tannins were found. In general, there is a correlation in the presence of reducing sugars and proteins. Starch granules and oxalate salts were found in the style parenchyma of a few...

Nutritious tissue in petals of Annonaceae and its function in pollination by scarab beetles
Provedor de dados: 39
Autores: Gottsberger,Gerhard; Webber,Antonio Carlos.
ABSTRACT The feeding of pollinating dynastid-scarab beetles on nutritious tissue of Annonaceae flowers results in macroscopically visible gnawing marks on petals. In the present paper, we present and discuss examples of such gnawing marks on Annonaceae from the Cerrado and the Amazon Forest in Brazil. The localization of gnawing marks on the petals and the histochemistry of the nutritious tissues are emphasized. In some species, nutritious tissue is apparently distributed among all petals, while in other species it is more or less diffusely localized. There are also cases in which nutritious tissue occurs only on clearly localized regions of the inner petals. Petals of selected Amazon species were stained, and studied by light and scanning electron...

Evaluation of Digestibility of Cooked Rice Grain using in vitro Digestion Technique
Provedor de dados: 111
Autores: Ogawa, Y.
Impact of postharvest and/or food processing (such as flour milling to agricultural and food-resource materials) on the digestibility of foodstuffs was investigated through a simulated gastro-intestinal in vitro digestion technique. The differences among the starch digestibilities of cooked rice grain and slurry were examined. In vitro digestion techniques are commonly applied to starch-based milled materials such as flours used for bread making. However, rice is not usually milled to flour but cooked as a whole for consumption. Therefore, maintaining an intact structure of cooked grain during in vitro digestion is very important to evaluate its starch digestibility. Two hundred grams of polished rice grain were cooked using electric rice cooker with 300...

Provedor de dados: 114
Autores: Medina,R.; Burgos,A.; Difranco,V.; Mroginski,L.; Cenóz,P.
The effects of chlorocholine chloride (CCC) and paclobutrazol (PBZ) foliar application on shoot and root parameters of cassava field-grown plants were studied (0, 45 and 90 mg active ingredient per plant). CCC and PBZ reduced total plant and first branch height, aerial fresh mass and tuberous root number. PBZ delayed branching and significantly decreased tuberous root fresh mass, while CCC caused no modifications in these parameters. In addition, CCC and PBZ treatments did not modify tuberous root diameter, while PBZ reduced tuberous root length significantly. Starch content was increased by both growth regulators at the lower dose, whereas dry matter content was increased only by CCC. In conclusion, CCC suppresses excessive vegetative growth, favours...

Autores: Assad-Bustillos,Melissa; Ramírez-Gilly,Mariana; Tecante,Alberto; Chaires-Martínez,Leandro.
Huauzontle seeds (Chenopodium berlandieri spp. nuttalliae) are produced in the central part of Mexico but their use is limited to seedling process. Thus, in order to diversify their applications it is necessary to study their components such as proteins and starch. Therefore, the objective of this study was to extract and characterize the starch contained in the seeds of huauzontle by means of chemical and physical techniques. Analysis of the results showed 50 % extraction yield, 72.5 % starch purity, 5.32 % moisture, 1.09 % ash, 0.083 % fat, 11.4 % total nitrogen, and 4.13 % crude fiber. The amylose content was 10.5 %, which suggests that huauzontle starch gels could have a low tendency to retrograde. Swelling and solubility were similar to reported...

In this work, the effect of lactic acid and UV irradiation on the physicochemical and structural characteristics of cassava and corn starches was evaluated. Only the modified cassava starch presented baking expansion capacity. From RVA, reduction of viscosity values, greater internal stability and none set back for modified cassava starch were observed. Modified corn starch did not show any peak viscosity. There were no significant differences in DSC thermal properties of treated and native starches. Amylopectin and amylose molecules from both the modified starches displayed some degradation. Molecular weight of cassava amylopectin was mostly preserved, whereas corn amylopectin was evenly attacked through the granule. Nevertheless, the B long branched...

Provedor de dados: 52
Autores: Lima,Luiz Carlos de Oliveira; Chitarra,Adimilson Bosco; Chitarra,Maria Isabel F.
Changes in amylase activity, starch and reducing and non-reducing sugars contents were monitored during ripening of mango fruits (Mangifera indica L.). The climateric raising in mango fruit is marked by an appreciable increase in the activity of amylase, reducing and non-reducing sugars contents and decrease in the starch content. The fruit affected with spongy tissue exhibited much lower amylase activity and reducing and non-reducing sugars, but exhibited much higher starch content during storage at 12 ± 2° C and 90 ± 5% RH for 28 days, when compared to healthy tissue of ‘Tommy Atkins’. Whether this is caused due to adverse effects on certain enzyme activities during ripening is not clearly known. These dates showed that carbohydrate metabolism is an...

Glycemic index: effect of food storage under low temperature
Provedor de dados: 52
Autores: Carreira,Marina Cassab; Lajolo,Franco Maria; Menezes,Elizabete Wenzel de.
This study was carried out to evaluate the influence of food storage under low temperature (-20ºC) and the resistant starch formation, both on the glycemic index (GI). The GI of only cooked and cooked and stored foods under -20ºC for 30 days was evaluated in short-term tests with humans. Significant increase on the RS content was evidenced for all the stored foods. The food storage resulted in a significant decrease on the GI of beans and chick-peas; the GI of pasta remained the same and the GI of corn meal increased. Thus, the RS formation showed reduced influence on the glycemic index. The storage of starchy foods under low temperature can collaborate to the RS intake but its effect on the GI will depend on the characteristics of the carbohydrates of...

Autores: Nwagu,Tochukwu Nwamaka; Okolo,Bartholomew Ndubuisi.
In this work, an α- amylase producing Fusarium sp. was isolated from the soil at 50 0C. Growth and enzyme production occurred at 30, 45 and 55 ºC. Soybean meal at 1% concentration, supplemented with 0.2% NH4Cl and 2.5% corn starch elicited the highest amylase yield. Optimum pH for the enzyme was pH 6.5 which retained over 60% of its activity after 24 h incubation at the pH range of 4.5-7.0. The enzyme showed high activity from 40-70 0C with optimal activity at 50 ºC and 78% activity was retained after incubation at 70 ºC for 30min. Catalytic function of the crude amylase was stimulated by Mg (136%), Ca (118%) and Zn (118%) at 2mM concentrations. The enzyme hydrolyzed cassava, potato and yam starches effectively.

The treatments consisted of four abomasal infusions: water (control), 4 g/kg BW.d-1 of partially hydrolyzed starch (SH), 0.6 g/kg BW.d-1 of casein, and a mix of SH + casein. The small intestine was collected and five equidistan, 1m sites were identified (duodenum, jejunum 1, jejunum 2 jejunum 3 and ileum). Maltase specific activity in mucosal homogenate and brush border membrane vesicles, SGLT1 protein abundance, and sodium-dependent glucose uptake in brush border membrane vesicles did not differ between the calves receiving different abomasal infusion treatments. However, maltase specific activity in homogenates and brush...

Provedor de dados: 58
Autores: Huang,Mian; Zhang,Song.
The study was conducted to evaluate effect of Coriolus versicolor mycelia on degrading starch and improving nutrition value in corn grits through solid state fermentation technique. The results showed that using soybean meal as a nitrogen source, α-amylase secreted from C. versicolor expressed 407.25U/g of activity, leading to 45.15% of starch degraded. The activity grew with fermentation time until the 15th day, after that the amylase was deactivated rapidly. An orthogonal experiment designed for the study illustrated that degradation rate of starch in corn grits attained to maximum, 50.51%, when 100g of corn grits, added 16g of soybean meal, were fermented by C. versicolor for 12 days, in an initial pH 5.5. After fermenting, compared to the nonfermented...

Application of microbial α-amylase in industry - A review
Provedor de dados: 58
Autores: Souza,Paula Monteiro de; Magalhães,Pérola de Oliveira e.
Amylases are one of the main enzymes used in industry. Such enzymes hydrolyze the starch molecules into polymers composed of glucose units. Amylases have potential application in a wide number of industrial processes such as food, fermentation and pharmaceutical industries. α-Amylases can be obtained from plants, animals and microorganisms. However, enzymes from fungal and bacterial sources have dominated applications in industrial sectors. The production of α-amylase is essential for conversion of starches into oligosaccharides. Starch is an important constituent of the human diet and is a major storage product of many economically important crops such as wheat, rice, maize, tapioca, and potato. Starch-converting enzymes are used in the production of...

Provedor de dados: 58
Autores: Boukraa,Laïd; Benbarek,Hama; Moussa,Ahmed.
To evaluate the synergistic action of starch on the antifungal activity of honey, a comparative method of adding honey with and without starch to culture media was used. Candida albicans has been used to determine the minimum inhibitory concentration (MIC) of five varieties of honey. In a second step, lower concentrations of honey than the MIC were incubated with a set of concentrations of starch added to media to determine the minimum synergistic inhibitory concentration (MSIC). The MIC for the five varieties of honey without starch against C. albicans ranged between 40% and 45% (v/v). When starch was incubated with honey and then added to media, a MIC drop has been noticed with each variety. It ranged between 7% and 25%. A negative correlation has been...

Provedor de dados: 60
Autores: Rechia,Letícia Mello; Morona,Juliana Bergman de Jesus; Zepon,Karine Modolon; Soldi,Valdir; Kanis,Luiz Alberto.
The aim of this study was to investigate the mechanical properties of starch/glycerol/Melissa officinalis, a topical drug delivery system for labial herpes treatment. Four films were prepared with different concentrations of starch, glycerol, and Melissa officinalis extract. The results revealed that increasing the glycerol concentration in the film reduced elasticity modulus and tensile strength, exhibiting a plasticizing effect. The increase in free volume resulted in increased release of hydroxycinnamic derivatives expressed as rosmarinic acid.
