Abstract

In this work, a total of 97 MRS-grown and 135 M17-grown lactic acid bacteria strains were isolated from 20 goat’s raw milk cheeses, and their antimicrobial, acidifying, and proteolytic activities were determined in vitro. Principal component analyses adjusted to a subset of 84 promising isolates evidenced that, for MRS isolates, antagonism against Staphylococcus aureus correlated well with higher acidification potential, whereas for M17 isolates, the antagonisms against S. aureus and Listeria monocytogenes were more correlated. The outcomes highlighted various strains with pathogen inhibition ability and satisfactory technological properties that may be useful for the development of a customised starter culture.
