Pickled vegetable was used as test material,4 strains of lactic acid bacteria were isolated.And the fermenting properties of the 4 strains of lactic acid bacteria were studied further,such as acid value,the concentration of diacetyl,soluble N of pH 4.6 and extracellular polysaccharose.The results show that the lactic acid bacteria 1 and 2 are appropriate for cheese making.
