why is gelatin liquefied in the presence of gelatinase?
Principle of Gelatin hydrolysis test. Gelatin hydrolysis test is used to detect the ability of an organism to produce gelatinase (proteolytic enzyme) that liquefy gelatin. Hydrolysis of gelatin indicates the presence of gelatinases. This process takes place in two sequential reactions. In the first reaction, gelatinases degrade gelatin to polypeptides.
