Conteúdo: |
In this study, 47 staphylococcal strains, isolated from milk of mastitic cattle from Brazilian dairy herds, were tested for antimicrobial substance (AMS) production. Fourteen strains were shown to produce AMS. Most AMS were sensitive to proteolytic enzymes, suggesting that they might be bacteriocin-like inhibitory substance (BLIS). (...) The BLIS+ strains 4244 and 5580 produce BLIS that seem to be distinct from the best characterized staphylococcal bacteriocins described in the literature. The BLIS produced by S. hyicus 4244, hyicin 4244, had the ability to inhibit all 30 strains tested as targets, including food-borne pathogens, such as Listeria monocytogenes and S. aureus. Both pathogens were also inhibited in a food matrix, suggesting that hyicin 4244 has potential biotechnological application as a food biopreservative. |
