Degradation of acetate in MES systems
Acetate is a core product synthesized in microbial electrosynthesis (MES), and its production requires the participation of a variety of microorganisms. However, recent studies have revealed that the acetate was gradually degraded, which resulted in the fail of MES, while the reason of acetate degradation and microbiomes associated with acetate degradation have not yet been investigated in detail. In this study, DNA-SIP and sequencing techniques were utilized to explore the reason of acetate degradation and to reveal the taxa and succession patterns of the degrading microbiome.
