Engineered Biofilms for Bioenergy Generation and Wastewater Treatment in Microbial Fuel Cells (MFCs)

在这项研究中，我们的目标是改善MFC产生的电能和微生物将电子转移到电极的机制。目前正在进行利用微生物燃料电池系统进行废水处理和生物发电的实验室研究。本文综述了微生物燃料电池中生物膜的形成、性质、特性及其在能源领域的应用。为实验室设置准备了基本材料。研究人员访问了污水处理厂，收集了原污水，这是目前研究的有机物的来源。通过购买所需的材料和化学品来建立实验工作。一个试验批次正在调查中。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值、混合培养物与特定培养物等）的操作，有必要进行初步的一系列批试验，以确定细菌增殖和生物膜形成的最佳条件。预计通过增加与阳极室中厌氧消化期间释放的可用电子相比的电子传输量来增加MFC的库仑效率。

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.
