Abstract

To isolate and identify lactic acid bacteria(LAB) from spoiled food and investigate the effect of different factors on biofilm formation.The strains were identified by the biochemistry methods.Biofilm formation was tested by microtiter-plate method under the different nutrient conditions,temperature and pH.The strains' biofilm was detected by microtiter-plate method.37℃,42℃and pH4 suboptimal for growth increased the production of biofilm.Low concentration of sodium chloride enhanced the biofilm formation(BF),but above a certain level,BFs were restrained.Different concentrations of glucose have different effect on strains' biofilm formation at different temperatures.BFs were spread widely among lactic acid bacteria from spoiled food.Preventing the formation of BFs has its significance in food preservation.

Key words： lactic acid bacteria; biofilm formation; cultivation conditions
