摘　　要：将出芽短梗霉G2m3.44经紫外和微波诱变后,挑选出一株产色素含量较低、产短梗霉多糖含量较高的菌株UV-63-MW-15。经固定化后,接种于麦芽根、淀粉废水糖化液中进行发酵。结果显示,其多糖产量高出游离细胞UV-63-MW-15的26.5%,是游离原始出发菌株G2m3.44细胞所产多糖量的2.63倍。The strain UV-63-MW-15 producing less pigment but more pululan polysaccharide was screened from Aureobasidium pullulans G2m3.44 mutagenized by ultraviolet and microwave. After being immobilized, the strain was inoculated into the starch wasteater added with ground malt root to produce pullulan polysaccharide. The yield ofpullulan is higher 26.5% than that of the pullulan polysaccharide produced by the free UV-63-MW-15 strain, and is 2.63 times of that of the pullulan polysaccharide produced by the free original strain.
