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，我们的目标是改善 MFC 产生的电能以及微生物将电子转移到电极的机制。目前正在进行实验室研究，利用微生物燃料电池系统进行废水处理和生物发电。关于生物膜的形成、性质、具体特征及其在微生物燃料电池应用中能源领域的应用的详细文献综述。为实验室设置准备了必要的材料。研究人员参观了废水处理厂，收集了原废水，这是本次研究有机物的来源。通过购买所需的材料和化学品来设置实验工作。一批试验正在调查中。值得注意的是，一组实验需要45天才能完成。考虑到不同反应条件（温度、pH、混合培养物与特定培养物等）的操纵，进行初步系列批量测试对于确定细菌繁殖和生物膜形成的最佳条件是必要的。预计会提高细菌的库仑效率与阳极室厌氧消化过程中释放的可用电子相比，通过增加传输的电子量来实现 MFC。
