Energy, food and water supply are the most challenging demands in modern and developing societies. Microbial desalination cell technology is a promising technology which can perform saltwater desalination, electricity generation and wastewater treatment simultaneously. Various factors influence overall performance of MDC technology which is significantly dominated by inoculum composition in mutual interaction to other factors. Bacterial metabolism is inhibited due to salt stress occurs during system operation and desalination process, which in a challenging limitation in scaling up such technology. In this paper inoclum of Shewanella oneidensis MR-۱ and Escherichia coli pure culture have been compared to co-cultured system, and the OCV and desalination efficiency have been evaluated on a basic three-chambered MDC equipped with an air cathode fed sodium lactate and sodium acetate as anolyte.
