| 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. |
| Keywords: | pentose hexose co-fermentation ruel alcohol |
