Bacteriocins are antimicrobial peptides produced by bacteria and Achaea. This study was focused to isolate bacteriocin producing bacteria from dairy effluent and the species were screened for antimicrobial and probiotic characteristics. The strains 3 and 5 confirmed highest antimicrobial activity against multidrug resistant pathogens such as Escherichia coli, Staphylococcus aureus, Streptococcus sp, Klebsiella pneumoniae, Enterobacter aerogenes, and Proteus vulgaris and negative activity was found against Bacillus subtilis. The strains showed high antimicrobial activity at neutral pH and temperatures in the range of 30-50ºC. The strains were also tested for antibiotic resistance as well as acid and bile salt tolerance tests.
