Microbial Fuel Cells (MFC) can be employed in bio-remediation of organic pollutants. In In this study, MFC voltage generated from various fruit market wastes using Clostridium spp., Proteus spp. and rumen fluid microbes was fitted into linear, logistic and Gompertz growth models. The dual chamber MFC was constructed using 1.0 liters plastic containers. NaCl in 3% agarose based salt bridge was used to connect the two chambers while graphite rods and copper wires were used as electrodes. The study was done by inoculating microbes present in about 250 mL cow dung mixed with 250 mL water and 500 g of homogenized fruit wastes and market wastes respectively, then current/ voltage generated measured for 24 days. The control experiment had 250 mL cow dung spiked with water to 1000 mL. From this study, microscopic and biochemical studies of the cultures confirmed that Pro.. View more»
