营养成本是生物质发酵生产乙醇的一个重要方面。为了开发一种经济有效的发酵培养基，对几种工业上可获得的营养源在预处理的白杨与酿酒酵母D（5）A同时糖化和发酵中的有效性进行了评价。这些研究表明，含有0.3%玉米浆和2.5 mM MgSO4的低成本培养基。7H（2）O在性能上与营养丰富的培养基相似。除了其低成本之外，这种替代介质由可在商业规模上获得的组分组成，从而使其具有工业相关性。
Nutrient cost is an important aspect in the fermentation of biomass to ethanol. With a goal of developing a cost-effective fermentation medium, several industrially available nutrient sources were evaluated for their effectiveness in the simultaneous saccharification and fermentation of pretreated poplar with Saccharomyces cerevisiae D(5)A. These studies showed that a low-cost medium containing 0.3% corn steep liquor and 2.5 mM MgSO4 . 7H(2)O was similar in performance to a nutrient-rich medium. Besides its low cost, this alternative medium consists of components that are available on a commercial scale, thereby making it industrially relevant.
