Abstract :Brevibacillus agri D505b is an aerobic, non-pathogenic, endospore-forming facultative thermophilic bacillus. Six abiotic surfaces insert ignore into journalissuearticles values(stainless steel, glass, polyvinyl chloride, polypropylene, polystyrene, and polycarbonate); were compared with viable cell enumerations. According to results, D505b cells could able to attach all these surfaces. Stainless steel insert ignore into journalissuearticles values(6.10 log CFU/cm2); was found to be the most effective surface for biofilm formation. Polycarbonate insert ignore into journalissuearticles values(6.03 log CFU/cm2); was found as the second best surface. Furthermore, the D505b biofilm was treated with 15 different sanitation agents and trichloroacetic acid insert ignore into journalissuearticles values(TCA); was determined to be the most effective one insert ignore into journalissuearticles values(80.3% removal);. Our results showed that the strong biofilm producer B. agri D505b was very resistant to various sanitation agents. However, TCA significantly inhibited biofilm formation for the isolate.
