Description Not Available
In the present study, 3 bacterial cultures were isolated from
faecal samples of human infant. The biochemical traits showed
similarity with Lactobacillus sps and 16S rRNA sequence analyses,
confirmed as Lactobacillus plantarum, Lactobacillus casei,
and Lactobacillus rhamnosus. The cultures were screened for
their proteolytic activity and good ability to release peptides
from milk proteins was found. Hence, these bacteria were used
as a proteolytic starter culture for the fermentation of skim
milk and whey for the liberation of small peptides. Bioactive
nature of the peptides released from whey and skim milk was
tested, and results demonstrated that peptides obtained after
fermentation of whey and skim milk by Lactobacillus strains
showed antimicrobial activity against all the pathogens causing
food borne infections in humans. These peptides also
indicated antioxidant as well as ACE (angiotensin-converting
enzymes) inhibitory activity.
