Quantitative strains of saccharomyces cerevisiae Meyen ex E.C. Hansen

Culture medium	Yeast extract: 3.0, malt extract: 3.0, glucose: 10.0, casein peptone: 5.0, agar: 20.0,pH:6.2±0.2(25 ℃)
Subculture procedure	① According to the culture conditions, the bacteria are first cultured into a bacterial suspension; ② Measure the absorbance of the bacterial suspension and calculate the initial concentration of the bacterial suspension according to the standard formula; The initial concentration multiplied by the survival rate is the actual concentration after freeze-drying; ④ According to the actual concentration after freeze-drying, the bacterial suspension was diluted to obtain the target concentration, and then subpacked and freeze-dried.
