Diversity of microbiota in Slovak summer ewes’ cheese “Bryndza”

Abstract

Abstract “Bryndza” cheese is an important Slovak traditional regional product. New knowledge on the role of microorganisms involved the “Bryndza” ripening process may provide valuable data on its quality and safety. In our study, the “Bryndza” made from pasteurized ewes milk was studied towards total count of bacteria, coliforms bacteria, enterococci, lactic acid bacteria, and microscopic filamentous fungi. All those groups of microbiota were detected using classical microbiological methods and identified using mass spectrometry. A total of 3,758 isolates were identified with score higher than 2.00. Altogether, 13 families, 24 genus, and 44 species of microbiota were identified in Slovak cheese “Bryndza.” The most often isolated species were yeasts Yarrowia lipolitica and Dipodascus geotrichum and the lactic acid bacteria Lactobacillus paracasei subsp. paracasei.
