Review of cathodic electroactive bacteria: Species, properties, applications and electron transfer mechanisms

Cathodic electroactive bacteria (C-EAB) which are capable of accepting electrons from solid electrode provide fresh avenues for pollutant removal, biosensor design and electrosynthesis. This review systematically summarized the burgeoning applications of the C-EAB over the past decade, including 1) removal of nitrate, aromatic derivatives and metal ions; 2) biosensing based on biocathode; 3) electrosynthesis of CH
