Abstract
The peptide hydrolase system of Bifidobacterium infantis, B. longum an d B. adolescentis revealed the presence of aminopeptidase, dipeptidase , tripeptidase, carboxypeptidase and caseinolytic activity. A rather s pecific trypsin-like activity hydrolyzing benzoyl arginine P-nitroanil ide was also detected in the 3 species of Bifidobacterium. PAGE electr ophoresis revealed the presence of one aminopeptidase and two dipeptid ases in each of the strains tested.
