摘要: This study was conducted to determine if stimulated meat starter culture (MSC; Pediococcus acidilactici) would further control Escherichia coli O157:H7, Listeria monocytogenes, and Staphylococcus aureus during salami fermentation. Manganese ion (0.005% of MnSO4) used as a stimulator for the growth acid production MSC. After 24-h fermentation, nonstimulated MSC reduced E. O157:H7 levels by 1.3 2.3 log10 units, respectively. Nonstimulated L. monocytogenes 1.2 whereas achieved 2.2-log10 reduction after In case S. aureus, units Stimulated MnSO4 those foodborne pathogens more effectively compared with (P < 0.05).
