| 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... |

| 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... |

| This study tried to monitor the alterations of muscle enzymes activity - creatinokinase (CK), lactate dehydrogenase (LDH), and aspartate aminotransferase (AST) - in a group of horses that participated of 70 and 100km distance rides in five competitions of an annual endurance championship under tropical climate. Pre ride levels (U/l) were 245.13±9.84 for CK, 496.61±14.76 for LDH, and 328.95±8.65 for AST. When compared to these levels, the results revealed a significant decrease in all enzymes activities in the first moment of the rides. Peak levels, significantly different, were reached, immediately after rides by CK (413.591±50.75); 24 hours post rides by LDH (628.61±33.30); and 48 hours after rides by AST (389.89±16.96).

| 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... |

| 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... |

| 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... |

| ABSTRACT: The aim of this study was to evaluate the biochemical responses of maize, under saline stress, inoculated with Bacillus subtilis. Four levels of salinity were assessed: 0mM, 50mM, 100mM, and 200mM of sodium chloride (NaCl). Saline conditions influenced negatively maize growth. However, the inoculation of B. subtilis improved the plant growth at highest level of NaCl. Chlorophyll content decreased while proline increased in inoculated plants submitted to highest salt levels. Also, B. subtilis increased the relative water content in leaves. B. subtilis improves the plant growth under salinity and ameliorates the biochemical damages in maize. |
