A brief review of nutritional studies for Penaeus monodon ArchiMer
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.

Nery, Marcela Carlota; Rocha, Adriana de Souza; Pinho, Édila Vilela de Resende Von; Santos, Heloisa Oliveira dos; Fialho, Cintia Maria Teixeira; Nery, Fernanda Carlota.
The seeds of a sesame crop contain approximately 50% oil content, one of the main reasons for their cultivation. However, information regarding methodologies for the assessment of quality seeds of this culture are scarce. Therefore, the objective of this study was to adapt the methods of accelerated ageing tests for sesame seeds and investigate changes in the behaviour of isoenzymes. The physiological characterization of the seeds and electrophoretic analysis of the isoenzymes superoxide dismutase, esterase, catalase, alcohol dehydrogenase, malate dehydrogenase and isocitrate lyase were also performed. For the accelerated ageing test, the seeds were subjected to the traditional method, with a saturated NaCl solution, at ageing times of 0, 24, 48, 72, and...

Activation of nitrate reductase of cashew leaf by exogenous nitrite Braz. J. Plant Physiol.
Viégas,Ricardo Almeida; Silveira,Joaquim Albenísio Gomes.
Nitrate reductase (NR) plays a central role in plant primary metabolism and exhibits complex regulation mechanisms for its catalytic activity. There is controversy in the literature concerning the possible direct effect of NO2- on the stimulation and/or activation of NR activity. The influence of NO2- was studied on the NR activity in the leaves of 30-day-old cashew (Anacardium occidentale L.) seedlings. Addition of NO2- to the reaction mixture containing leaf enzymatic extract resulted in a remarkable increase in NR activity. A trace amount (5 mumol.L-1) of NO2- was required to achieve full NR activity. The in vitro NR-activity showed a steady time-dependent increase when incubated in the presence of only NO3- + NO2-. In contrast, in vitro NR activity was...

Activity of cellulase from Thermoactinomycetes and Bacillus spp. isolated from Brassica waste compost Scientia Agricola
Chang,Chen-Chin; Ng,Chang-Chai; Wang,Chung-Yi; Shyu,Yuan-Tay.
Plant wastes present a high cellulose content, which is an ideal organic material for composting. Five strains of thermophiles from processed Brassica waste were isolated, and the hydrolytic activity on various cellulosic biomass substrata and their temperature profiles were determined. 16S rRNA sequencing identified these strains as Thermoactinomyces and Bacillus spp. Maximal cellulase activity corresponded to 2.3 U mL-1 of enzyme. The application of these strains on Brassica rapa residues demonstrates increased total nitrogen content). TA-3, a Thermoactinomycetes sp. strain, performs best among all inoculants, increasing the nitrogen content from 0.74 to 0.91%, and decreasing the carbon content from 15.4 to 12.2%, showing its high efficiency and...

Analysis of binding properties and specificity through identification of the interface forming residues (IFR) for serine proteases in silico docked to different inhibitors. Repositório Alice
RIBEIRO, C.; TOGAWA, R. C.; NESHICH, I. A. P.; MAZONI, I.; MANCINI, A. L.; MINARDI, R. C. de M.; SILVEIRA, C. H. da; JARDINE, J. G.; SANTORO, M. M.; NESHICH, G..
Background: Enzymes belonging to the same super family of proteins in general operate on variety of substrates and are inhibited by wide selection of inhibitors. In this work our main objective was to expand the scope of studies that consider only the catalytic and binding pocket amino acids while analyzing enzyme specificity and instead, include a wider category which we have named the Interface Forming Residues (IFR). We were motivated to identify those amino acids with decreased accessibility to solvent after docking of different types of inhibitors to sub classes of serine proteases and then create a table (matrix) of all amino acid positions at the interface as well as their respective occupancies. Our goal is to establish a platform for analysis of...

Anatomy and physiology of digestive tract of crustaceans decapods reared in aquaculture ArchiMer
Ceccaldi, H.
The digestive tract of crustacea is complex. It is composed of a shor t oesophagum, a stomach with two bags, and internal wall with appendags specialized in grinding of feeds. These hard mastication pieces represent the gastric mill. Setae, filters included in the stomach structure allow the separation between food particles and liquid compounds. Those one are coming over through filters and more on to the digestive gland tubules or mid gut gland. In this organ, several types of cells play specialized functions: absorption, enzyme secretion, stocking function. Some cells of a new type, with undefined function, may be neurosecretions function, have been described recently. The end of tubules of digestive gland exhibits cells with embryonic characteristics....

ABSTRACT The objective of this study was to evaluate the effect of a mixture of direct-fed microbials (DFM), yeast, and digestive enzymes on animal performance in feedlot cattle, as well as digestibility when finishing feedlot cattle. Thirty crossbreed (Charolais × Beefmaster) steers averaging 15 months old and 321.83±3.73 kg of initial body weight were used. Animals were randomly assigned to one of two treatment groups: control (basal diet) and a mixture of DFM, yeast, and digestive enzymes (basal diet + 30 g of the mixture). Each group contained fifteen experimental units. Animals were fed individually twice a day, and dry matter intake (DMI) was recorded daily. Body weights were recorded initially and subsequently at 28-day intervals for a total of 140...

Annual production of grass silage for biogas: effects of fibrolytic enzyme additives on ensilage efficiency and specific methane yields CIGR Journal
Nolan, Pearl; Doyle, Evelyn; O'Kiley, Padraig.
The aims of this study were to quantify the effects of fibrolytic enzyme additives applied to each of four consecutive cuts of unwilted grass at ensiling on ensilage characteristics and specific CH4 yields (SMY) per unit mass and per unit land area. In light of the importance of the primary growth yield, the effects of the timing of Cut 1 were also investigated. Furthermore, the mass-SMY and area-SMY effect of any effluent produced during ensilage was determined.At each of four cuts that comprised annual growth, samples from four replicate plots of Lolium perenne and of Phleum pratense were untreated (control) or were treated with either of two fibrolytic enzymes (ENZ 1 and ENZ 2) prior to ensiling for 120 days. The mass-SMY of silages and effluents were...

Antioxidant system response induced by aluminum in two rice cultivars Braz. J. Plant Physiol.
Ribeiro,Cleberson; Cambraia,José; Peixoto,Paulo Henrique Pereira; Fonseca Júnior,Élcio Meira da.
The antioxidant defense system response was evaluated in two rice cultivars (Oryza sativa L.), Fernandes (CNA-1158) and Maravilha (CNA-6843-1), treated with toxic levels of aluminum. After exposure to aluminum we determined plant growth, H2O2 and O2•- contents, lipid peroxidation, antioxidant enzymes activities and ascorbate and dehydroascorbate contents. Al predominantly accumulated in roots of both cultivars but it reduced root and shoot growth only in the Maravilha cultivar. Treatment with aluminum resulted in a reduction of 84 and 60% in the levels of H2O2 in the roots of the cultivars Maravilha and Fernandes, respectively, and of 26% in the levels of O2•- only in the roots of Fernandes cultivar. Increased lipid peroxidation was observed only in the...
