中文摘要：
利用单室空气阴极微生物燃料电池（MFC）反应器,以玉米秸秆为底物,以本实验室筛选和保存的纤维素降解菌Chaetomium sp.和Bacillus sp.,以及纤维素降解混合菌PCS-S和H-C为秸秆降解的生物催化剂,探讨了以汽爆秸秆固体为底物进行微生物产电的可行性.结果表明,在MFC系统内,纤维素降解纯菌和混合菌均能使纤维素降解,但产生的电压很低（〈90mV,1000Ω）,升高温度（30～38.5℃）对电压输出无明显影响.单独以生活污水作为菌源不能直接降解秸秆产电.只有将H-C和生活污水（产电菌源）混合作为接种体,MFC才能获得较高的电压输出.此时得到的以汽爆秸秆固体作为底物时的最大功率密度为406mW.m-2,仅比葡萄糖作为底物时所得到的最大功率密度510mW.m-2低20%.
英文摘要：
The possibility of direct electricity production from steam exploded corn stover residue was studied in single chamber air-cathode microbial fuel cells（MFCs）using two cellulose degrading bacteria（Chaetomium sp.,Bacillus sp.）and two cellulose degrading communities（PCS-S and H-C;stored in our laboratory）as biocatalysts.Both pure strains and mixed communities can decompose corn stover in MFCs,but little electricity（〈90 mV,1000Ω）was generated during this process.Increasing the temperature from 30 to 38.5℃ did not increase voltage outputs.Using domestic wastewater solely as inoculum,electricity cannot be generated from degradation of corn stover.Maximum voltage was observed in the MFC using H-C co-operated with the exoelectrogenic bacteria.The maximum power density from steam exploded corn stover residue was 406 mW·m-2,which was only 20% lower than the 510 mW·m-2 obtained using glucose as a substrate.
