摘　　要：研究金针菇深层培养获得胞外多糖及胞内多糖的最佳发酵条件。结果表明,金针菇深层培养最佳条件为:培养周期8d、培养温度25℃、摇床转速140r/min、接种含量8%、起始pH值自然,获得最大胞外多糖收率的最佳培养时间为9d,获得最大胞内多糖收率的最佳培养时间为7d。The fermentation condition of Flainmulina velutipes in submerged culture to obtain the extracellular polysaccharide and the intracellular polysaccharide was studied. The results indicated that the optimum condition of Flainmulina velutipes in submerged culture was cultivation cycle of 8 d, cultivation temperature of 25 ℃, rotational speed of 140 r/min, vaccination quantity of 8%, initial pH of value nature. The optimum cultivation time of obtaining the biggest extracellular polysaccharide yield was 9 days, while the optimum cultivation time of obtaining the biggest intracellular polysaccharide yield was 7 days.
