Biological methane production coupled with sulfur oxidation in a microbial electrosynthesis system without organic substrates
文献摘要：
Methane is produced in a microbial electrosynthesis system(MES)without organic sub-strates.However,a relatively high applied voltage is required for the bioelectrical reactions.In this study,we demonstrated that electrotrophic methane production at the biocathode was achieved even at a very low voltage of 0.1 V in an MES,in which abiotic HS-oxidized to SO42-at the anodic carbon-cloth surface coated with platinum powder.In addition,mi-crobial community analysis revealed the most probable pathway for methane production from electrons.First,electrotrophic H2 was produced by syntrophic bacteria,such as Syn-trophorhabdus,Syntrophobacter,Syntrophus,Leptolinea,and Aminicenantales,with the direct acceptance of electrons at the biocathode.Subsequently,most of the produced H2 was con-verted to acetate by homoacetogens,such as Clostridium and Spirochaeta 2.In conclusion,the majority of the methane was indirectly produced by a large population of acetoclastic methanogens,namely Methanosaeta,via acetate.Further,hydrogenotrophic methanogens,including Methanobacterium and Methanolinea,produced methane via H2.
