In this research, we aim to improve the electrical energy generated by the MFC and the mechanisms by which microorganisms transfer electrons to electrodes. Laboratory investigation are currently under process for wastewater treatment and bioelectricity generation using Microbial fuel cell systems. A detailed literature review about biofilm formation, properties, specific characteristics, and their application for energy fields in Microbial Fuel Celles application. Essential materials were prepared for the lab-setup. The researcher visited the wastewater treatment plant to collect the raw wastewater,which is the source of the organix matter for the current study. The set-up of the experimental work, by purchasing the required materials and chemicals. A trial batch is under investigation. It is worth noting that one set of experiments needs 45 days to be completed. Conducting preliminary series of batch tests is necessary to determine the optimal conditions for bacterial multiplication and biofilm formation considering manipulation of different reaction conditions (temperature, pH, mixed-culture vs specific culture, etc.).it is predicted to increase the Coulombic efficiency of the MFCs, by increasing the amount of electron transported compared to the available electrons released during the anaerobic digestion in the anode chamber.

在这项研究中，我们旨在改善MFC产生的电能以及微生物将电子传递到电极的机制。目前，使用微生物燃料电池系统进行了废水处理和生物电力的处理实验室研究。有关生物膜形成，特性，特定特征及其在微生物燃料电池应用中应用的详细文献综述。为实验室设定准备了必需的材料。研究人员参观了废水处理厂，以收集原始废水，这是当前研究的组织物质的来源。通过购买所需的材料和化学品来设置实验工作。正在调查试用批次。值得注意的是，一组实验需要45天才能完成。必须考虑操纵不同反应条件（温度，pH，混合培养与特定的特定培养等）的细菌繁殖和生物膜形成的最佳条件，必须进行初步批量检验。
