Using food waste hydrolysate as medium for culturing oleaginous microorganism is a dual-purpose strategy for relieving environmental burdens both in food waste disposal and energy crisis. The pure culture of one oleaginous microorganism when single waste as culture media has shortages such as high operation cost, low lipid production and low substrate utilization. Mix-culture of yeast and microalgae in this work enhanced this process result in better waste treatment, higher lipid production and shorter cultivation time. Compare to pure culture of Rhodosporidium toruloides, the nitrogen utilization rate, reducing sugar utilization rate and lipid production increased by 23%, 17 and 12%, respectively, and the cultivation time shorten by 40%, in mix-culture of Rhodosporidium toruloides and Chlorella vulgaris. The results showed that the mix-culture of yeast and microalgae using food waste hydrolysate as culture medium would be a good strategy for both waste disposal and biofuel production.

使用食物垃圾水解产物作为培养油质微生物的培养基是减轻食物垃圾处理和能源危机中的环境负担的双重目的的策略。当单一废物作为培养基时，仅含一种油质微生物的培养存在操作成本高，脂质产量低和底物利用率低的缺点。这项工作中酵母与微藻的混合培养增强了该过程，从而可以更好地进行废物处理，增加脂质的产生并缩短培养时间。比较的纯培养红冬孢酵母，氮利用率，减少的混合培养物的糖利用率和脂质生产分别增加23％，17％和12％，和40％缩短培养时间，红冬孢酵母和小球藻。结果表明，以食物残渣水解物为培养基，将酵母菌和微藻混合培养是处理废物和生产生物燃料的良好策略。
