利用甘蔗糖蜜发酵生产花生四烯酸的研究
Arachidonic acid production from cane molasses by Mortierella alpina
摘要
Abstract
Arachidonic acid (ARA) fermentation by Mortierella alpina was carried out using cane molasses.Several different preparation methods were investigated to evaluate the optimal process of cane molasses method.The results indicated that sulfuric acid process was the best method.The cultivation parameters were as follows:reducing sugar concentration 80 g/L,nitrogen resource concentration 6 g/L,inoculum density 20%,initial pH 6.0,and cultivation temperature 25 ℃.The resultant dry cell weight,total lipid content,arachidonic acid yield,and sugar utilization were 28.5 g/L,11.7 g/L,3.68 g/L,and 94.5%,respectively.关键词
