Abstract :
Almost all moist surfaces are colonized by microbial biofilms. Biofilms implicated in cross-contamination of food products and various human infections such as dental cavities. In this investigation three bacterial samples were used for biofilm formation in 48 hrs in laboratory condition. Biofilms was determined by using spectrophotometric technique to overcome hazardous effect of biofilm on these biomaterials is suggested in this research. To subside the biofilms these parameters were used in the culture and after 24, 48, and 72 hrs. 0 day has been taken at 450 for S. aureus and at 600 for both E. coli and Salmonella spp. The result was found that this chemical parameter showed antimicrobial activity and was capable to inhibit the biofilms formation. The preservatives were more effective acetic acid for maggi bottle, benzoic acid for pickle bottle and sodium sulphite for both fizz bottle and coke cane.
