摘要

摘要: 考察玉米芯经草酸热裂解预处理后产生的热裂解液在单室空气型阴极微生物燃料电池（microbial fuel cell，MFC）中的降解及产电特性。玉米芯草酸热裂解预处理的最佳条件为：反应温度160℃，反应时间90 min，草酸用量（质量分数）2%时，可产生的还原糖浓度为0.44 g/g，固体消化率约为58%。当采用稀释20倍的酸式热裂解液时，MFC最大功率密度为278 mW/m²，产电周期约为120 h。使用不同浓度玉米芯酸式热裂解液的MFC对COD去除率均可达到90.0%以上，随着稀释倍数的降低，MFC库仑效率从18.6%降低至9.72%。MFC阳极微生物群落在属水平上，典型产电细菌Geobacter属的相对丰度最高达到3.40%；Klebsiella属在使用稀释20倍酸式热裂解液下的相对丰度达到41.6%。研究结果为强化玉米芯在MFC中的有效利用提供了参考。

Abstract: The aim of this study is to explore the electricity generation properties in the single-chamber air-cathode microbial fuel cell (MFC) with corn cob acid pyrolysis solution as the substrate. The optimized conditions for the pretreatment of corn cob with oxalic acid pyrolysis were as follows:reaction temperature of 160℃, reaction time of 90 min, oxalic acid dosage of 2% (by mass percentage). Under the optimized condition, the concentration of reducing sugar was 0.44 g/g corn cob and the solid digestibility was about 58%. Fed by the 20 times diluted solution of acid pyrolysis, the MFC could produce the maximum power density of 278 mW/m². The period of electricity generation in the MFC was about 120 h. The COD removal rate in the MFC fed by different concentrations of corn cob acid pyrolysis solution reached more than 90.0%. With the decrease of the diluted factor, the coulombic efficiency (CE) of MFC decreased from 18.6% to 9.72%. Under different concentrations of corn cob hydrolysate, the highest relative abundance of Geobacter, a typical electrically active bacteria (EAB), was 3.40% in the bacterial community in the anodic biofilm of MFC at the genus level. The relative abundance of Klebsiella reached 41.6% under 20 times diluted corn cob acid pyrolysis solution. The results provided a scientific basis for the effective utilization of corn cob in MFC.
