The complement system is one of the host’s primary defence mechanisms against pathogens. Its activation involves proteolytic cascades enzymatic reactions that result in products with effector functions and recognition molecules on surface microorganisms [1,2].

The objective of this study was to identify Acinetobacter in a traditional cheese from west Azarbaijan, Iran, and to study the lipolytic and proteolytic activities of these bacteria in ripening of white brine cheese. Acinetobacter is a gram negative bacteria which can be found in different sources as dairy products. Lypolysis and proteolysis characteristic of this bacteria and...

Mangroves are complex, unique, and dynamic ecosystems that host organisms have special physiological adaptations to fluctuations in salinity, temperature, pH. Gastropods an important role the mangrove ecosystem for food cycles webs by helping provide nutrients micro-habitats microbes. Micro-fungi isolated from productive sources of enzymes bioactive compounds such as antibacterial antifungal. I...

A qualitative and quantitative characterization of the proteolytic activity of a number of rat liver cell fractions was undertaken using lY51-labeled hemoglobin as substrate. The results indicated that proteolytic activity in rat liver was of two major types. The first was characteristic of activity accounted for by the endopeptidase cathepsin I). It was sensitive to the inhibitor pepstatin, an...
