Abstract

Disclosed are methods for increasing microbial catalase production. 1-10 g/L sodium hexametaphosphate was added to the culture medium between 30-40 hours of fermentation to inhibit proteinase activity and increase the production of catalase. This simple modification of fermentation procedure can result in up to 45% increase of the production of catalase.
