Microbial community analysis of chain-elongation microbial electrosynthesis systems integrating sequential enrichment and a conductive polymer-modified cathode
This study investigates changes in microbial community structure associated with strategies for enhancing chain elongation in microbial electrosynthesis (MES). 16S rRNA gene amplicon sequencing was performed for three MES configurations: co-inoculation (MES-1), sequential inoculation and enrichment (MES-2), and sequential inoculation and enrichment combined with a PEDOT:PSS-modified cathode (MES-3). The dataset was generated to compare microbial community composition among the three systems and to identify microbial taxa potentially associated with volatile fatty acid production, chain elongation, biofilm formation, and extracellular electron transfer.
