Bacteriocin with a broad antibacterial spectrum against various Gram positive, Gram negative food borne and multidrug resistant pathogens, and against some fungal pathogenic strains (Ref.1, Ref.2). Displays bacteriocidal activity against L.monocytogenes ATCC 7644 (MIC=80 ug/ml), and inhibits the growth of M.luteus KIBGE-IB20 (MIC=160 ug/ml), P.aeruginosa ATCC 27,853 (MIC=80 ug/ml), S.aureus KIBGE-IB23 (MIC=160 ug/ml), B.cereus ATCC 11,778 (MIC=80 ug/ml), E.coli ATCC 8739 (MIC=80 ug/ml), E.faecalis ATCC 29,212 (MIC=40 ug/ml), A.terreus KIBGE-IB-35 (MIC=40 ug/ml) and A.flavus KIBGE-IB34 (MIC=20 ug/ml) (Ref.2). Has no activity against B.licheniformis KIBGE-IB3, A.niger KIBGE-IB-36 and A.fumigatus KIBGE-IB33 (Ref.2). Optimum pH is 6.5 (Ref.1, Ref.2). Retains 70% of its antibacterial activity at pH 8.0 and pH 5.5 (Ref.2). Optimum temperature is 35 degrees Celsius (Ref.1, Ref.2). Highly thermostable (Ref.2). Retains 60% of its antibacterial activity after heating to 100 degrees Celsius for 3 hrs (Ref.2). Stable during storage at -10 degrees Celsius and loses no activity during storage for 6 months (Ref.2). Highest expression in the early stationary growth phase, with expression decreasing after the end of the stationary phase.
