Stimulatory Effect of Flammulina velutipes Polysaccharide on Lactic Acid Bacteria Growth and Lactic Acid Fermentation

Abstract

　The present study examined the effect of Flammulina velutipes polysaccharide (FVP), a kind of water soluble polysaccharide extracted from the fruiting body of Flammulina velutipes, on the growth of lactic acid bacteria of Lactobacillus delbrueckii subsp. bulgaricus 2b and lactic acid fermentation in skim milk culture media incubated at 37℃. It was found that the FVP could stimulate the bacteria growth by a reduction in the lag-phase time and promote the lactic acid fermentation. It was also found that this effect was positively related to the FVP concentration in the skim milk culture medium.
