A lipase from a newly isolated thermophilicRhizopus rhizopodiformis.

Two strains ofRhizopus rhizopodiformis that produced lipases in broth culture were isolated. Maximum lipase production (23 U/ml) was obtained after 72 h culture. Both the crude lipases were stable at 50°C for 30 min and at 45°C for 24 h. Maltose was the best carbon source and peptone the best nitrogen source for the production of lipases. Only glycerol and lecithin stimulated lipase production further.
