1. Evaluation of alternative ingredients in diets of broilers with the addition of enzymes / Avaliação de ingredientes alternativos na alimentação de frangos de corte com a adição de enzimas
Two experiments were conduced to evaluate the inclusion of alternative ingredients, sunflower meal and sorghum, in diet of broilers with the addition of enzymes. The experiments were divided into three independent trials, which corresponded to each phase of raising: initial phase (1 21 days), where the performance characteristics were evaluated; growing phas

2. Enzymatic depolymerization of emulsan.
Emulsan, the polyanionic emulsifying agent synthesized by Acinetobacter calcoaceticus RAG-1, was depolymerized by an enzyme obtained from a soil bacterium YUV-1. The extracellular emulsan depolymerase was produced when strains RAG-1 and YUV-1 were grown together on agar medium. The enzyme was extracted from the agar and concentrated by ultrafiltration and am

3. Mechanism of Enhancement of Virus Plaques by Cationic Polymers
It has been assumed that plaque enhancement by cationic polymers is due to their binding of sulfated polysaccharides in agar. However, viruses that are enhanced by cationic polymers, diethylaminoethyl-dextran, and protamine were found not to be inhibited by polyanions in agar under the usual overlay conditions. In the case of adenovirus, enhancement by prota
