In this paper, a novel strategy for lipid production through coupling oleaginous yeasts and activated sludge biological methods by cultivation of Rhodotorula glutinis in cellulosic ethanol wastewater was studied. Under optimal conditions in wastewater medium (dilution ratio of 1:2 and glucose supplement of 40 g/L), the maximum biomass and lipid content as well as the lipid yield reached 11.31 g/L, 18.35% and 2.08 g/L, with the associated removal rates of COD, TOC, NH₄⁺-N, TN and TP reaching 83.15%, 81.81%, 85.49%, 70.52% and 67.46%, respectively. Cellulosic ethanol wastewater treated by the anaerobic-aerobic biological process resulted in removal of COD, NH₄⁺-N, TP and TN reaching 67.55%, 94.17%, 90.16% and 48.89%, respectively. The reused water was used to dilute medium of R. glutinis for microbial lipid production reaching 2.38 g/L and caused positive effects on the accumulation of biomass and lipid.

本文研究了一种新的策略，通过在纤维素乙醇废水中种植油酵母（Rhodotorula glutinis），通过油质酵母和活性污泥生物方法的耦合生产脂质。在废水介质的最佳条件下（稀释比为1：2，葡萄糖补充量为40 g / L），最大生物量和脂质含量以及脂质产量分别达到11.31 g / L，18.35％和2.08 g / L， COD，TOC，NH ₄ ⁺ -N，TN和TP的相关去除率分别达到83.15％，81.81％，85.49％，70.52％和67.46％。厌氧-好氧生物工艺处理的纤维素乙醇废水导致COD，NH ₄ ^+的去除-N，TP和TN分别达到67.55％，94.17％，90.16％和48.89％。再利用的水被用于稀释谷氨酸棒杆菌的培养基以产生2.38g / L的微生物脂质，并且对生物量和脂质的积累产生了积极的影响。
