| Abstract: | A suitable productive condition of the extracellular polysaccharide from Cryptococcus laurentii was studied. The composition of a medium is as following (g/L): glucose 80, yeast extract 1.25, KH2PO4 3.0, MgSO4 - 7H2O 0.05, CaCO3 10.0, pH 6.0. When culture incubated on rotary shaker at 30℃ for 6 days, The yield of extracellular polysaccharide reached 17.38 g/L. The conversion rate of glucose was 21.725%. |
