Abstract: The performance of lactic acid bacteria has important influence on the quality of fermented yoghourt.In this study,six strains of lactic acid bacteria were isolated from yoghourt with six brands differently in market,and the characteristics of the lactic acid bacteria,about the morphological,physiological and fermentation performance,were studied comparatively.The results showed that six strains of lactic acid bacteria are similar in growth rate and lactic acid production,but different in morphology,physiology and fermentation performance.

Key words: yoghourt, lactic acid bacteria, fermentation characteristics
