Production of microbial rennin

Fungal strains were compared for their ability to produce milk-coagulating enzyme with low non-specific proteinase activity.Rhizomucor miehei VTT-D-82193 (ATCC 16457) was chosen as the best source of microbial rennin. The enzyme produced compared favourably with two commercial coagulant preparations of microbial origin. The work provides a basis for comparison with other production processes for microbial rennin, including recombinant chymosin.
