研究了使用几内亚玉米壳和小米壳（农业废物，没有明显的工业价值或作为食品的竞争性用途）作为生产生物乙醇的替代和具有成本效益的原料。所使用的方法包括：用2.5M H2SO 4酸解，并分别用从土壤和棕榈酒中分离的尼日尔和运动发酵单胞菌进行同步糖化和发酵。玉米皮和谷子皮在120 h时乙醇产率最高，分别为26.83g/l和18.31g/l，乙醇浓度分别为67.7%和63.8%。尼日尔曲霉和运动发酵单胞菌可能是利用玉米皮和谷子皮生产乙醇的较好菌种。
关键词：玉米皮，谷壳，水解，糖化，发酵，蒸馏。
The use of guinea corn husk and millet husk (agricultural waste with no appreciable value to industries or competitive use as food) as alternative and cost-effective feed stock for the production of bioethanol was examined. The methods used, included: acid hydrolysis with 2.5 M H2SO4, and simultaneous saccharification and fermentation with Aspergillus niger and Zymomonas mobilisisolated from soil and palm wine, respectively. Ethanol yield from guinea corn husk (26.83 g/l) and millet husk (18.31 g/l) was maximum at 120th h and with ethanol concentrations of 67.7 and 63.8%, respectively. The least ethanol concentration of 30% was obtained with A. niger on millet husk. A. niger and Z. mobilis may be better organisms for ethanol production from Guinea corn husk and millet husk.
Key words: Guinea corn husk, millet husk, hydrolysis, saccharification, fermentation, distillation.
