| Abstract: | The metabolite of propionibacterium sp.is a new sort of natural preservative.The effect of nitrogen, carbon,surfactant and temperature on the antimicrobial activity of Propionibacterium freudenreichii metabolites were studied in this paper.The results showed that glucose and corn steep liquten were the best carbon and nitrogen,and the highest antimicrobial activities were 19 AU/mL and 17.4 AU/mL,respectively.The antimicrobial activity was increased to 23.6 AU/mL in the culture medium added 0.1%Tween80.The b... |
