Abstract

Yeast cells that express rennin or prorennin are used in disrupted cellular form to clot milk without the need for purification of the rennin or prorennin. Cheese making is simplified and reduced in cost by the avoidance of substantial purification techniques to obtain rennin or prorennin from living cells which produce these materials.
