Abstract
The increasing awareness of consumer against the health hazards of synthetic preservatives has created a demand for more natural and chemical free processed foods. Bacteriocins synthesised by lactic acid bacteria LAB are receiving much attention as natural bio-preservatives in food due to their active inhibitory against foodborne pathogens and spoilage bacteria. The aim of this study was to determine the inhibitory spectrum of bacteriocin-producing strains obtained from an indigenous fermented fruit. The inhibitory activity against selected foodborne pathogens was evaluated by well diffusion method and only strains with good antimicrobial activity was identified. Thirty-two strains of LAB were identified namely Pediococcus pentacaceous Lactobacillus paracasei Lactobacillus delbruekii Lactobacillus plantarum Lactobacillus rhamnosus and Lactobacillus brevis. Nineteen isolates produced anti-listeria activity and 11 strains demonstrated antagonistic activity against Staphylococcus aureus ATCC 25923 Salmonella typhimurium ATCC 13311 Salmonella enteritis ATCC 13076 Yersina enterocolitica ATCC 23715 and Vibro parahaemolyticus ATCC 17802. Results showed that 52 of the LAB strains exhibited moderate inhibitory effect while 16 showed strong inhibition against Listeria monocytogenes. These results suggest the bacteriocin-like substances produced by LAB could be potent natural antimicrobial agents against foodborne pathogens. However further studies should be carried out to identify and characterize the bacteriocins responsible for the inhibitory activity.
