Abstract

The recurring increase in the energy demand, coupled with the over- consumption of nonrenewable sources of energy has led to the exploration and use of renewable and cost effective energy resources. In this context, present study deals with the utilization of sewage sludge, which contains high levels of readily biodegradable organics and is also one of the major sources of environmental pollution, as substrate in a microbial fuel cell (MFC). Saccharomyces cerverciae sp. as a mediator and potassium ferricyanide as an oxidizing agent were used for the conversion of sewage organics into electric current and power generation using lab-scale double chamber MFC. The cells were connected in series with the anodic and cathodic solutions being introduced in batch and continuous modes. A maximum voltage of 830mV (3.3 mA) was obtained per liter of the sludge with the anode in batch- feed and cathode in continuous modes of operation under optimum conditions of the operating parameters of oxygen flow rate, pH and substrate concentration.
