production method
Kluyvermyces an endocellular enzyme produced under controlled conditions of lactis, containing bovine coagulase B gene embedded protoplast pUCl8. The fermented mash is adjusted to pH 2 to convert casein into rennet and kill the cells produced. After filtration, rennet is separated from the cell material, and then purified by diatomite, and then filtered multiple times and one ultrafiltration.
