Description
Summary: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 <i>Staphylococcus aureus</i> correlated well with higher acidification potential, whereas for M17 isolates, the antagonisms against <i>S. aureus</i> and <i>Listeria monocytogenes</i> 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.
