【摘要】 秸秆是一种来源广泛,价格低廉的可再生资源。本实验以C.butylicum A86为产氢菌,对以汽爆玉米秸秆为原料的固态发酵产氢进行了研究,探索了秸秆利用和生物制氢的新途径。实验结果表明,C.butylicum A86能够利用秸秆在汽爆和酶解过程中产生的多种糖类,并能够和纤维素酶在低pH值下发挥协同作用,产氢率达44.5 ml H2/gcSES,底物利用率为25%。更多还原

【Abstract】 Straw is a kind of renewable resource with wide source and low price. In this experiment, steam-exploded com straw (SECS) was used for the solid-state fermentation of hydrogen by C. butylicum A86 to find a new way for the utilization of straw and biological hydrogen production. The results show that the saccharides produced by the steam-explosion and enzymolysis of straw could be utilized by C.butylicum A86, and that C.butylicum A86 could cooperate with cellulase at low pH. The yield of H2 was 44.5 ml H2/gcSES and the conversion ratio of manteials was 25%.更多还原
