Microbial biofilms are of special concern to dairy and food industry, as biofilms on raw materials or food contact surfaces represent possible sources of contamination with spoilage or pathogenic microbes. The present study was carried out to evaluate biocide resistance profiles of biofilm forming bacteria of dairy niche towards commonly used biocides and their control in biofilm formation. Genetically confirmed 17 isolates of genera Bacillus, Staphylococcus, Salmonella, Pseudomonas, Listeria and E. coli were evaluated for their biocide resistance profiles by determining their minimum inhibitory concentration (MIC) and also microbial biofilm eradicating concentration (MBEC) against commonly used biocides (iodophore, sodium hypochlorite, and benzalkonium chloride) in dairy/food industry. The Listeria, Salmonella and Staphylococcus exhibited highest MBEC against iodophore (550 ppm), Listeria against sodium hypochlorite (550 ppm); Bacillus, Pseudomonas, Listeria and consortia against benzalkonium chloride (650 ppm). Benzalkonium chloride and sodium hypochlorite were found most efficacious against all tested isolates and their consortia as they could reduce higher log counts after treatment in comparison to iodophore.
