Determinação da temperatura para inativação da urease em amostras de casca e farelo de soja

s not degraded in the rumen but destroy ureasis. Soybean meal is one of the protein ingredients commonly used in formulations of animal feeds. In the diets of monogastric bran has high protein content provided by a greater separation of soybean hulls. For the ruminant protein value of the meal is lower with the inclusion of soybean hulls to reduce the level of protein. With the increased consumption of meal high protein, due to increases in production of pigs and poultry in recent years, increasing the availability of soybean hulls on the market, this is because soybean hulls is little understood in the feeding of monogastric . In this context, the main objective of this study was to determine the times and temperatures needed to ensure the effective inactivation of ureasis present in the bran and soybean hulls. According to the assessments, to make the determination of temperatures and times required for the inactivation of ureasis present in the bran and soybean hulls are 170 º C and 25 minutes for soybean meal and 140 ° C 10 minutes for soybean hulls, respectively

Biosurfactants production by yeasts using soybean oil and glycerol as low cost substrate

Biosurfactants are bioactive agents that can be produced by many different microorganisms. Among those, special attention is given to yeasts, since they can produce many types of biosurfactants in large scale, using several kinds of substrates, justifying its use for industrial production of those products. For this production to be economically viable, the use of residual carbon sources is recommended. The present study isolated yeasts from soil contaminated with petroleum oil hydrocarbons and assessed their capacity for producing biosurfactants in low cost substrates. From a microbial consortium enriched, seven yeasts were isolated, all showing potential for producing biosurfactants in soybean oil. The isolate LBPF 3, characterized as Candida antarctica, obtained the highest levels of production - with a final production of 13.86 g/L. The isolate LBPF 9, using glycerol carbon source, obtained the highest reduction in surface tension in the growth medium: approximately 43% of reduction after 24 hours of incubation. The products obtained by the isolates presented surfactant activity, which reduced water surface tension to values that varied from 34 mN/m, obtained from the product of isolates LBPF 3 and 16 LBPF 7 (respectively characterized as Candida antarctica and Candida albicans) to 43 mN/m from the isolate LPPF 9, using glycerol as substrate. The assessed isolates all showed potential for the production of biosurfactants in conventional sources of carbon as well as in agroindustrial residue, especially in glycerol.

Soybean compressibility and bulk density

The objective of this project was to study the influence of surcharge pressure and moisture content on the compressive behavior and bulk density of soybeans. Three varieties were selected with varying dimensions and shapes. Moisture contents of 10.5, 15.0, and 20% were tested at nine surcharge pressures in the range from 0 to 82.8 kPa. Results indicated that the bulk densities of different soybean varieties have similar behavior with respect to pressure level and moisture content but that the magnitude of bulk density was influenced by variety, Bulk density was influenced by both pressure level and moisture content. The four-element Burger model was found to adequately describe the bulk density of soybeans as a function of pressure for all varieties and moisture levels.
