In the preceding experiments, it is confirmed that the expiration date of Kimchi varies depending on the storage temperatures. Therefore, to provide the basis materials about set up of accurate expiration date of Kimchi, it experienced the relationship of temperature and pH of bacteria growing in the fermentation process of Kimchi. Leuconostoc citreum has the highest dry cell mass 26.699 g/L when the highest return value 1.295 in pH 7.0. Weissella koreensis the highest dry cell mass 27.125 g/L when the highest return value 0.850 in pH 6.0. And Lactobacillus sakei has the highest dry cell mass 17.848 g/L when the highest return value 0.616 in pH 7.0.
