Effects of initial pH on heat resistance of Lactobacillus plantarum LIP-1

Abstract In order to study the effect of different initial pH values on heat resistance of the strain, the changes in heat stress survival rates of Lactobacillus plantarum LIP-1 and its potential influencing mechanisms were investigated under different initial pH values. The results showed that the growth L. plantarum LIP-1 did not significantly differ according to initial pH value (P > 0.05), but there were significant differences in heat stress survival rates among initial pH values (P
