Abstract通过富集培养并利用选择性培养基分离筛选到2种能适应味精生产过程中离交尾液(COD为4069mg/L,NH4^+—N含量为16914mg/L)的酵母菌,经鉴定分属于嗜盐假丝酵母(Candida halophila)和粘红酵母(Rhodotorula glutinis),这种混菌合培养时在pH4~9范围内其COD去除率均可达到80%以上,对于10倍、3倍、2倍稀释的离交尾液,48h之内,其COD去除率均可高达84.5%,日平均去除速度COD/SS均在1.0kg/(kg·d)以上,远高于对照的活性污泥法[对于10倍稀释液最高去除率为78.9%,去除速度为0.34kg/(kg·d),同时也高于国内报道的其他酵母菌菌株,经处理后,还原糖可去除95.7%,而NH4^+—N没有明显变化。
