利用热纤梭菌7072对玉米秸秆进行高温发酵，建立了一种高效的产氢工艺。将125 mL厌氧发酵瓶转化为100 L连续搅拌反应器，生物反应器系统具有良好的混合和传质性能，可显著提高玉米秸秆产氢效率。100 L连续搅拌釜反应器中的氢气产率达到61.4 mL/g玉米秸秆，高于125 mL厌氧瓶中的氢气产率。本研究表明，利用C.热纤是一种很有前途的生物产氢途径。
An efficient hydrogen production process via thermophilic fermentation of cornstalk was developed by Clostridium thermocellum 7072. The hydrogen fermentation process was successfully scaled from a 125 mL anaerobic bottle to a 100 L continuous stirred-tank reactor, and the hydrogen production from cornstalk was significantly improved in the bioreactor system because of good mixing and mass transfer. The hydrogen yield in the 100 L continuous stirred-tank reactor reached 61.4 mL/g of cornstalk, which was higher than that in the 125 mL anaerobic bottle. The present work indicated that direct microbial conversion of lignocellulosic waste via C. thermocellum was a promising avenue for biohyclrogen production.
