Isolation, Identification and Control of Contaminated Bacteria from Brake Can

摘要

Nine heat-resistant spore-forming bacteria strains were isolated from the juice of blown brake can, which sterilized at 100°C. With can be the systematic bacteria identification, these strains were determined as Bacillus subtilis, Bacillus megaterium, and Bacillus pumilus. During the antimicrobial test, it was found that Nisin is the best among the three food preservatives in antimicrobial activity. Its mode of action is rupturing the cells, thus killing the.
