ELECTRICITY GENERATION USING DIFFERENT SUBSTRATES AND THEIR DIFFERENT CONCENTRATIONS IN MICROBIAL FUEL CELL

摘要

The need of electricity is getting increasing today due to industrial and technological requirements. It is also known that fossil oils are harmful to nature and getting exhausted. Due to these factors it is necessary to find both new and green electricity resources. Microbial fuel cell (MFC) as biofuel is one of them. It provides both nature-friendly electricity and treatment of wastewater. In this study, glucose and ethanol as substrates and their different concentrations were used both to treat wastewater and generate electricity. Multimeter was used to measure the voltage values of each substrate concentrations. It was proven that each substrate had different effect on microbial community. It was found that glucose was the most effective substrate for electricity generation in the concentration of 3000 mg/l total organic carbon (TOC).
