摘　　要：粘红酵母ＧＬＲ５１３产油脂条件施安辉谷劲松刘淑君肖海杰（山东大学微生物技术国家重点实验室济南２５０１００）当今无论是食用油脂，还是工业用油脂，国内外均非常短缺，寻求新的油脂来源任务迫切。利用微生物生产油脂具有：不受季节和气候的影响；油脂含量高；生产原...We utilized the protoplast fusion techinique,ultroviole light and EMS to induce original strain,and got the mutant GLR513 next we made research for the best culture conditions for lipid fermentation.The result is the best carbon source is glucose,the best nitrogen source is (NH4)2SO4,C:N is 70:1,initial pH is 5.5,and it is necessary to maintain this value during fermentation,the inoculation volume is 20%,optimum temperature is 30℃,fermentation time is 72h,during fermentation more glucose need.At the end of the fermentation,the maximum lipid content 67.2% can be achieved.Analysed with MS and GC,the lipid consists of 56.51% unsaturated fatty acid they are palmitoletic acid 34.3%,oleic acid 3.8%,linoleic acid 2.00%,linolenic acid 10.2%,EPA2.6%,DHA3.6%.
