title: Effect of protein hydrolizates on growth kinetics and aminopeptidase activities of some Bifidobacterium species.
abstract: This study evaluated the effect of a new hydrolizate from poultry feathers on growth kinetics and aminopeptidase activities of eight bifidobacteria compared with common peptones. The growth kinetics results suggest that the experimental hydrolizate could be a cheaper medium ingredient without affecting the modulation of common aminopeptidase activities.
