Research Carbon and Steel Surfaces Modified to work as a biocatalyst for the anodic reaction of the MFC, generating electricity via degradation of organic matter. Until by Leptothrix discophora SP-6: recently, biocathode MFCs have been a relatively unchartered territory. Characterization and Implications The microbial colonization of passive metals has been reported to increase their open circuit potential (OCP) to † † , ‡ final values between +200 mVSCE (1) and +450 mVSCE (2, 3) T U A N A N H N G U Y E N , Y U Z H U O L U , § through a series of reactions collectively termed ennoblement.
