Abstract:

Bacteriocins are antibacterial proteins produced by bacteria that kill or inhibit the growth of other bacteria. Four methionine producing microorganisms isolated from sago industrial waste namely Candida tropicalis S1O1, Kluyveromyces marxianus S2O1, Acetobacter tropicalis S3O1, and Lactobacillus paracasei subsp. tolerans S6O2 were tested for bacteriocin activity against pathogenic bacterial strains, Bacillus cereus (MTCC 1272), Escherichia coli (MTCC 2622), Listeria monocytogenes (MTCC 1143), Staphylococcus aureuss (MTCC 1144). Among the four methionine secreting microorganisms, Acetobacter tropicalis S3O1 exhibited good bacteriocin activity against Bacillus cereus (MTCC 1272) and Staphylococcus aureus (MTCC 1144). The sensitivity of the bacteriocin towards temperature, pH and various enzymes were also investigated.


Keywords: Sago waste, Methionine bacteria, Bacteriocin activity, Characterization.
