Abstract
The production of a rennin of high milk coagulating activity and low proteolytic acitivity from a selected strain of Mucor miehei which is useful in cheese making.
Claims6
A microbial rennin having relatively high milk coagulating activity and relatively low proteolytic activity and being relatively free from lipase obtained by cultivating a selected strain of Mucor miehei (NRRL No.'s:
- 3169, A7772, A13131, A13042, and 2543) in a medium containing available carbon, nitrogen and trace nutrients and fermenting under aerobic conditions.
The process of preparing a lipase-free rennin with a relatively high milk coagulating activity and relatively low proteolytic activity comprising fermenting under aerobic conditions a medium containing available carbon, nitrogen and trace nutrients and at least one Mucor miehei strain selected from the group consisting of NRRL No. 3169, No. A7772, A13131 and A13042 until a substantial amount of microbial rennin is produced and recovering a lipase-free rennin from the resulting fermentation medium.
