Abstract
Cheese is prepared using rennin obtained from insoluble refractile bodies of a recombinant microbial host cell. The rennin is obtained by rupturing the recombinant hose cell, isolating and solubilizing the insoluble refractile bodies, and recovering active rennin. Recombinant techniques involve preparing cDNA corresponding to the coding sequence for calf rennin, introducing into an expression vector and expressing in a host cell. As much as 200 mg rennin per liter of culture may be recovered. Prorennin or preprorennin may be produced and rennin derived therefrom.
