摘　　要：本试验利用金针菇液体发酵对小麦淀粉废水进行处理，同时获取菌丝体。发酵7d后，生物量达到最高值，COD去除率为70．8％。此后生物量逐渐下降，COD去除率略有上升。对所得的菌丝体的营养成分及氨基酸组成进行了分析。从菌丝体中提取到4种多糖，多糖的提取得率为0．60％A strain of Flammulina relutipes was used to treat starch processing wastewater. After fermenting for 7 days,the biomass reached the top point, and the COD removal rate was 70. 8% at that time. The biomass decreased and the COD removal rate slightly increased aftervards. The nutritional compositions of the mycelium were analyzed .4 kinds of polysaccharides were obtained from the mycelium with the recovery rate of polysacchdrides to the mycelium is 0 .60%.
