摘　　要：对粘红酵母处理味精废水的条件进行研究。结果表明最佳处理条件为:进水COD浓度为10000 mg/L,pH为6.16,发酵温度为32℃,发酵时间为72 h,接种量为15%。该条件下可使味精废水COD的去除率达80.53%以上,利用发酵后的菌体,可提取单细胞蛋白,提取油脂,具有一定的应用潜力。The treatment of monosodium glutamate waste water by Rhodototula glutinis has been studied. The results indicate that the optimum conditions for operation of the process are： COD of the incoming water = 10000 mg/L, pH = 6.16, T = 32 ℃, t = 72 h and 15 % inoeulation volume. Under these eonditions, the COD ean be redueed by 80.53 %. The residual Rhodototual glutinis thalli ean be used to produee lipids and proteins, indicating that the process has eommereal potential.
