title: Conditions influencing the synthesis of acid protease by Mucor pusillus Lindt.
abstract: Protease synthesis by Mucor pusillus Lindt, in a wheat bran medium under submerged conditions, was influenced by substrate concentration, initial pH of the medium, and temperature of incubation. A 4% wheat bran (dry weight) concentration was satisfactory for enzyme production. The initial pH of the medium had a substantial effect on enzyme synthesis; adjustment of the enzyme production medium to pH 5.0 prior to sterilization was desirable. Incubation at 35 C resulted in the best enzyme yields. Under optimal conditions of enzyme production, maximal activity was detected after 5 days of incubation. The enrichment of the medium with glucose increased the yield of mycelia but lowered the amount of enzyme produced.
