Proteolytic activity of central-nervous-system tissue of the normal rat was examined over the pH range 2-9 with casein, haemoglobin and myelin basic protein as substrates. With casein as a substrate, brain and spinal cord homogenates showed very similar activity profiles with increasing pH, with the main peaks of proteolytic activity at pH 3-4 and 5-6. When haemoglobin was used, one broad main ...

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 thus its role in ...

Proteolytic activity in extracts of lymphatic tissue has been described in the older literature,11 gelatin, casein, and serum albumin having been used as substrates. More recently bovine tonsils were reported to contain a protease that cleaves serum albumin.7 Rothschild and Junqueirae found proteolytic activity in lymph node homogenates, using globin as substrate. In the present investigation, ...

A raw fish-juice was prepared and sterilized through the use of (60)Co gamma-irradiation. It was evaluated for suitability in an agar medium for testing the proteolytic activity of bacteria isolated from fish. Microorganism proteolytic activity was also detected by conventional methods with skim milk-agar. We tested 1,145 isolates from fresh and spoiling irradiated (0.0, 0.3, and 0.6 Mrad) yell...
