In a previous paper we found two groups of strains, a weak and strong halotolerant strain, which differed in halotolerance in Streptococcus and Pediococcus. In order to study the mechanism of the halotolerance property on halotolerant bacteria, we picked out the representative strains from each group and then compared the weak halotolerant strain and the strong halotolerant strain on the main comonents of cells.Little difference between weak and strong halotolerant strain on the nitrogen containing component was found. However the weak halotolerant strain, had a higher content of cabohydrate than the strong halotolerant strain, but the strong halotolerant strain had a higher content of total lipid and ash than the weak halotolerant strain. Furthemore the strong halotolerant strain had a higher content of acetone insoluble fraction than acetone soluble fraction in total lipid and a higher value in P/N molar ratio of acetone insoluble fraction.Little diference of the content of each cell component of the strong halotolerant strain in high and low concentration of sodium chloride, could be found, but the cell with high concentration of sodium chloride had a larger P/N molar ratio of acetone insoluble lipid than the cell in low concentration of sodium chloride.
