摘要: 利用高通量测序技术对阳极生物膜的微生物群落结构进行了分析.实验结果表明,高通量测序能够高效地获取电化学生物膜的群落结构信息,产电模式菌Geobacter属在生物膜中占据着优势地位,其数量比例达到30%左右,其次的主要菌属为Thermovirga,Thauera和 Syntrophorhabdus.对比电化学活性丧失前后的生物膜发现,虽然Geobacter菌属在丧失了电化学活性的生物膜中仍然占据统治地位,但是放线菌门的细菌增长显著,其数量比例远高于正常阳极生物膜的0.5%,有可能是抑制生物膜电化学活性的因素之一.

Abstract: Microbial community structure of anode biofilm was analyzed using high-throughput sequencing technology. The results show that the technology can obtain community structure information from electrochemistry biofilm efficiently, and the exoelectrogentic modal bacteria Geobacter category is predominant in biological membrane, its quantity ratio reaches 30%;Thermovirga,Thauera and Syntrophorhabdus are also found in anode biofilm. However, through comparison of biofilm before and after electrochemical activity was lost, Geobacter still dominated in biofilm after the biofilm lost electrochemical activity,while Actinomycetes’ proportion increased significantly, its quantity was much higher than that of the normal 0.5%. So Actinomycetes may be one of the factors which inhibit the electrochemical activity of the biofilm.

Key words: anode biofilm, bioelectrochemical system (BES);high-throughput sequencing, microbial diversity, 16S rRNA
