Abstract


In this study, it was investigated that the inhibition effect of some lactic acid bacteria (Lactobacillus acidophilus NCC68, Lactobacillus casei Shirota, Lactobacillus rhamnosus (Ezal, commercial starter cultures)) which possessed with probiotic characteristics, against Bacillus cereus, Salmonella Enteritidis, Escherichia coli, Escherichia coli 0157:H7 ATCC 35150 and Staphylococcus aureus ATCC 25923. Besides, the inhibitory effect of probiotic cultures which used with meat and meat product additives that garlic extract over the antagonistic effects of sensitive pathogens were investigated in vitro. Consequently, the whole of lactic acid bacteria and garlic extract which were used in this study, showed inhibition effects against all selected pathogenic bacteria. Staphylococcus aureus ATCC 25923 was determined as the most sensitive pathogenic bacteria while Bacillus cereus was the most resistant bacteria against lactic acid bacteria and garlic extract. There was a distinctive increase in inhibition effects were observed by used of a combination with lactic acid bacteria and garlic extract.
