Utilization of Saccharomyces cerevisiae for Enhanced Electricity Generation during Domestic Wastewater Treatment via Microbial Fuel Cell Technology

Abstract

Abstract:

The viable, cost-effective and energy-efficient wastewater treatment remains a curious concern among scientists. Microbial fuel cell (MFC) can offer such elegant solutions. MFC is an electrochemical system that converts chemical energy of chemical compounds into electricity via metabolic activities of microorganisms. MFCs are cost-effective methodology for wastewater treatment due to removal of contaminants from wastewater while at the same time producing electrical power. The wastewater, which is a source of enumerable extremophilic microbial flora, is used as inoculum in many recent studies. Wastewater acclimatization with efficient microflora can improve the performance of MFC. In present contribution, performance of MFC was compared on the basis of inoculum. The electricity generation and chemical oxygen demand (COD) removal behavior of raw wastewater (RW) was compared with that of inoculated wastewater (IW) (Saccharomyces cerevisiae). It was observed that Saccharomyces cerevisiae remarkably enhanced the performance. Up to 344 mW/cm2 power density and 96.5% COD removal was obtained during 30 days of operation.
