摘　　要：以葡萄糖为底物进行批量发酵实验,探究电化学厌氧消化中挥发性脂肪酸和微生物群落相对常规厌氧消化的变化.结果表明:与常规厌氧消化相比,电化学厌氧消化促进了挥发性脂肪酸的转化,提高了微生物群落的多样性和电活性微生物的丰度.Batch fermentation experiments were conducted using glucose as substrate to investigate the changes in volatile fatty acids and microbial communities in electrochemical anaerobic digestion relative to conventional anaerobic digestion.The results showed that electrochemical anaerobic digestion promoted the conversion of volatile fatty acids and increased the diversity of microbial communities and the abundance of electroactive microorganisms compared with conventional phase anaerobic digestion.

关 键 词：电化学厌氧消化 挥发性脂肪酸 微生物群落 电活性微生物
