Rhizomucor miehei (also: "Mucor miehei" ) is a species of fungus. It is commercially used to produce enzymes which can be used to produce a microbial rennet to curd milk and produce cheese. Under experimental conditions, this species grows particularly well at temperatures between 24 and 55°C, and their growth becomes negligible below 21°C or above 57°C. It is also used to produce lipases for interesterification of fats.
