考察了不同浓度Mn2+和卵磷脂对以玉米秸秆水解糖为原料发酵生产乙醇的影响。结果表明，在酵母发酵培养基中同时添加0.6 mmol/L Mn2+和60 mg/L卵磷脂进行乙醇发酵，终点乙醇浓度可达15.46%(V/V)，乙醇的得率达到49%。

The effects of different concentrations of Mn2+ and lecithin on the Ethanol fermentation were investigated by using corn stalk as raw material. The results showed that 0.6 mmol/L Mn2+ and 60 mg/L lecithin were added in the medium for ethanol fermentation， the final ethanol concentration was 15.46% (V/V) and the ethanol yield was 49%.
