Biochemical approaches for selection of starter cultures of lactococci and thermophilic streptococci based on their proteolytic activity

Abstract

Substrate properties of casein and whey protein fractions from skim milk during the protein reduction with proteolytic systems of mesophilic lactococci and thermophilic streptococci have been investigated. The level of proteolytic activity of Lactococcus spp. and Streptococcus salivarius subsp. thermophilus (14 strains) has been established on the basis of colorimetric studies and SDS-electrophoretic separation of products obtained by bacterial proteolysis.
