Glucose electro-fermentation with mixed cultures: A key role of the Clostridiaceae family

Electro-fermentation is a new type of bioprocess combining the concepts fermentation and electro-microbiology to improve conversion organic substrates into valuable products. During electro-fermentation metabolic profiles could be redirected by presence polarized electrodes through changes in microbial communities dark fermentation. This paper aims investigate influence bacterial community composition on glucose batch electro-systems. Our results showed that initial significantly impacted final related patterns. electro-fermentation, H2 yield was increased using anaerobic sludge but decreased activated as inocula. While other inocula from similar origins, no differences between traditional were evidenced. The relative abundance Clostridiaceae family members inoculum appeared determining factor affecting global performances. These findings provide insights mecanisms occurring mixed cultures.
