Screening of lactic acid bacteria of the highest yield of nisin LAB EPS symbiotic strains

Three strains of lactic acid bacteria and three strains of lactic acid bacteria of the high yield of LAB EPS are screened based on 10 strains producing Nisin lactic acid bacteria strains and 10 strains of producing LAB EPS strain of lactic acid bacteria were cultured,screened and determinated.One strain with high yield of Nisin strains of lactic acid bacteria symbiotic with one strain with high yield of EPS strains of lactic acid bacteria is screened by fermentation experiment.
