| Abstract: | Aureobasidium pullulans W2003 is a natural strain of producing pigment-free. The best fermentation conditions were determined by the method of single factor tests and orthogonal optimization experiments in this paper. The optimized culture conditions were as follows： 28℃, 150r/min, pH= 6.5, culture time 60h; Medium composition （g / L）： sucrose 70, yeast extract 10, KH2PO4 2.0, MgSO4·7H2O 1.0, NaOH 1.0, （NH4）2SO4 0.04. Under these conditions, polysaccharide content was 11.68g in culture fluid and the polysaccharide conversion rate was 16.68%. |
