Research objectives was to determine inhibition activities towards E. coli and Salmonella spp. by pickle's indigenous halotolerant bacteria. Experimental methods used in the research and data were analyzed descriptive-exploratory. In order to determine pickle's indigenous halotolerant bacteria, three isolates cultured on Nutrient Agar (NA) with addition of 5 and 10% (w/v) NaCl then the total bacteria population counted. Escherichia coli and Salmonella spp. inhibition activities determined by

Results showed that isolate P3 shown halotolerant characteristic with total bacteria population of 5.3 x 10 5 cfu/g on 5% NaCl then decreased into 5.2 x 10 3 cfu/g on 10% NaCl with no inhibition clear zone towards E.coli and 7.5 mm inhibition clear zone towards Salmonella spp..
