Milk-Clotting Protease From <i>Bacillus stercoris</i>NCCP-3139: A Potential Microbial Rennet for Cheese Production. [PDF]

Food Sci Nutr
A milk‐clotting protease from Bacillus stercoris NCCP‐3139 was isolated from soil and purified via ammonium sulfate precipitation and sequential chromatographic techniques, yielding a homogeneous enzyme confirmed by SDS–PAGE. The protease exhibited high catalytic selectivity, with a marked increase in milk‐clotting‐to‐proteolytic activity ratio (50–550)
