Anode Modification for Microbial Desalination Cell.

The salt water could be desalinated by microbial desalination cell (MDC) without energy supply and simultaneously produce bioenergy. One of the factors for support their sustainability perform is a modification of electrode. Anode modifications have been proposed for salinity reduction in saline water. Immobilization of yeast cells has been applied in MDC. Yeast as biocatalyst was used as electrogenic microorganism oxidized glucose then transfer electrons generated from yeast cells to carbon electrode mediated by neutral red as redox mediator. The results were characterized by chronoamperometry and confirmed that all the anodes modified could be a promising method for long-term performance of MDC based yeast cells. [ABSTRACT FROM AUTHOR]
