Omics and electro-fermentation reveal metabolic regulation of ethanol-H2-coproducing fermentation by Ethanoligenens

摘要：

　　To gain a deep understanding of understanding metabolic regulation is important for enhancing metabolites in the anaerobic digestion.Syntrophy is essential for global carbon cycling,waste degradation,and biofuel production.A single-chamber MEC aiming at verify the syntrophic relationship between fermentative bacteria and exoelectrogens by co-culture of Ethanoligenens harbinense and Geobacter sulfurreducens,succeeded.The results indicated that the co-culture facilitated the forming and maintaining of intimate connections between E.harbinense YUAN-3 and G.sulfurreducens PCA.G.sulfurreducens utilized the acetate efficiently,reduced the metabolic inhibition of strain YUAN-3 and increase the hydrogen production.Our study proved that electro-fermentation and interspecies syntrophic interactions between fermentative hydrogen-producing bacterium and exoelectrogen could regulate metabolites.
