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)

Structural Characterization and Hypoglycemic Effects of a Purified Polysaccharide From <i>Cinnamomum cassia</i>. [PDF]

Food Sci Nutr
CCP1A, a polysaccharide purified from Cinnamomum cassia with a molecular weight of approximately 8.16 kDa and rich in glucose and galacturonic acid, exerts anti‐type 2 diabetes effects through a multi‐target synergistic mechanism. On one hand, it delays intestinal glucose absorption by inhibiting the activities of α‐amylase and α‐glucosidase in the ...
