| Abstract: | In this study,4 Lactobacillus isolated from wine production area of Gansu and Ningxia province were identified.Then,Lactobacillus plantarum were used as the test strains to investigate the tolerance of pH value,alcohol and SO2 concentration in modified MRS medium.The 16S rDNA analysis showed that there were 3 Lactobacillus plantarum.Analysis of tolerance experiments showed that 3 Lactobacillus plantarum were able to grow in modified MRS medium under different conditions(pH 3.0 alcohol content 16%vol,SO2 concentration 110 mg/L).Under the compound conditions,all 3 strains could grow and proliferate well of pH 3.8,alcohol content 10%vol,SO2 concentration 45 mg/L.All 3 strains could be able to grow in the presence of pH 3.2,alcohol content 14%vol,SO2 concentration 45mg/L. |
