Proteases possuem um papel fundamental na economia, estando presentes em diversos setores industriais. Dentre os fungos conhecidos por produzir proteases, destaca-se o gênero Aspergillus. Desta forma, objetivo deste trabalho foi proteases a partir de fermentação estado sólido Aspergillus ochraceus, purificar, caracterizar e avaliar seu potencial produção enzima colagenolítica fibrinolítica. Par...

Pacific red snapper (Lutjanus peru) is an important commercial species in Mexico with great aquaculture potential; however, digestive physiology still unknown. Therefore, the objective of present work was to characterize proteases L. peru juvenile using biochemical and electrophoretic techniques. Results showed a higher acid protease activity than alkaline proteases, trypsin, chymotrypsin, leuc...

Abstract Dysregulated humoral immune mechanisms result in immunoglobulin production that is pathogenic and contributes to a wide range of autoimmune diseases transplant rejection. Proteases derived from human pathogens can specifically cleave these immunoglobulins (Ig) potentially eliminate circulating, cell-surface immune-complex Ig classes modulate Ig-mediated autoimmunity inflammation, provi...

Alkaline crude enzymes from the viscera of the Tunisian barbel (Barbus callensis) were extracted and characterized. Proteolytic crude extract from barbel viscera was active and stable in alkaline solution. The optimum pH and temperature were 11.0 and 55 °C, respectively, using casein as a substrate. The crude alkaline protease was extremely stable in the pH range of 5.0-12.0. Zymography activit...

Proteases are one of the predominant groups industrial enzymes and it represents for about 65% total global enzyme market. microbial origin have great importance over plant sources because they minimize production costs, increase characteristics desired products widely used in biotechnological process. Among protease enzymes, aspartic proteases most important proteolytic which mainly produced b...
