Abstract
The action of intracellular proteases of lactic acid bacteria (IPLB) at pH 7 on various paracaseins was studied. Paracaseins prepared by releasing of 3~7% non casein type nitrogen (NCN) were hydrolyzed by IPLB with more difficulty than native or other paracaseins prepared by releasing of less or above 3~7% NCN. This phenomenon was not found in a case of a neutral protease of Bacillus subtilis. Hydrolyzed casein by rennin or IPLB of S. cremoris were studied by DEAE-cellulose column chromatography, starch-gel or agar-gel electrophoresis. It was estimated that not only some part of α-casein but also β-casein were hydrolyzed by IPLB of S. cremoris.This publication has 0 references indexed in Scilit:
