摘要
利用不同菌种的固定化细胞对木质纤维素稀酸水解液进行乙醇发酵,对2#菌进行了以木糖为底物7个批次的驯化培养。利用4#与1#的混合菌及3#菌进行批式发酵以及4#和1#、1#和3#、4#和3#混合菌及3#菌进行补料批式发酵,结果表明,1#和4#及1#和3#混合固定化对木质纤维素稀酸水解液进行补料批式发酵,乙醇产率较为理想,分别为理论产率的79.3%和84.3%。
The batch-fermentation and fed-batch fermentation of dilute-acid lignocellulose hydrolysates to ethanol using different mixed immobilized cells have been studied. The results showed that the fed-batch fermentation of dilute-acid lignoeeilulose hydrolysates by immobilized cellsl # and 2 # which is domesticated with xylose as the sole carbon source for 7 batches, the domesticated 2 # and 3 # give high ethanol yields , which are respectively 79.3 % 和 84.3 %, respectively, compared with theortical ethanol yields.
