The process of ennoblement has been correlated with extracellular polymers (enzyme theory) and biogenic manganese dioxide deposition by many investigators.In the present study, to find out the role of cations and polymers on ennoblement process investigation has been undertaken on materials such as 6XN-SS (UNS NO8387); C 276 (UNS NO10276); Titanium gr2 (UNS NOR50250) for microbiological characterization and electrochemical studies. The quantum of manganese depositing heterotrophic bacteria was...
