It is of great benefit to recycle excess sludge, which is rich in inorganic and organic nutrients, as the substrate material for yeast growth. This study focused on the disposal of residual liquid of sludge after pretreatment. Candida utilis was firstly chosen to be cultivated in the sludge hydrolyzate for simultaneous efficient nutrients removal and yeast utilization through aerobic process.

通过利用假丝酵母培养去除污泥提取物中的营养并生产蛋白质

回收富含无机和有机营养物的过量污泥作为酵母生长的底物材料，这是非常有益的。这项研究的重点是预处理后污泥的残留液的处理。首先选择util丝假丝酵母在污泥水解产物中培养，以便通过好氧工艺同时有效地去除营养和酵母利用。
