摘 要:
研究了戊糖和己糖共发酵生产燃料乙醇发酵体系的影响因素.正交试验获得的最佳发酵体系为:在基础发酵培养基中添加φ(Tween-80)=0.025%,ρ(聚乙烯醇4000)=100g/L,p(L-谷氨酰胺):0.625g/L.在此条件下,发酵至72h时,乙醇产率为43、56%.[著者文摘]

Abstract:
The effects of some factors on fermentation system during co-fermentation of hexose and pentose to fuel ethanol were studied. The results showed that:The optimum fermentation system was obtained by orthogonal test as follows: adding Tween-80 0.025% ,PEG 4000 100 g/L, L-glutamine 0.625 g/L to basic medium,fermentation period was 72 h. The maximum producing rate of ethanol was 43.56 % in fermented liquid.[著者文摘]
