The chemical energy contained in wastewater can be considered as a promising sustainable energy source and can be recovered using microbial fuel cell technology by means of electro-active bacteria. There are several brewery industries releasing wastewater into the environment, posing serious environmental issues. Herein, we demonstrated treatment of brewery wastewater and production of bioelectricity simultaneously using double chamber MFCs by inoculating locally isolated microorganisms. Microorganisms were locally isolated from brewery waste sludge (named as BSGB1 and BSGB2), brewery wastewater (BWGB3 and BWGB4) and food processing industry waste sludge (FSGB5 and FSGB6). Total dissolved solids (TDS), chemical oxygen demand (COD), and biochemical oxygen demand (BOD) were determined before and after treatment of brewery wastewater by locally isolated microorganisms. The results revealed that the microorganisms isolated from brewery waste sludge outperformed the bacteria isolated from brewery wastewater and food processing industry waste sludge. The maximum power density of 0.8 W/m³ and 0.35 W/m³ was generated by MFC inoculated with locally isolated microorganisms from brewery waste sludge using the synthetic and real-brewery wastewater, respectively. The removal efficiency of COD was 79−83%, indicating significant treatment of brewery wastewater by locally isolated microorganisms while generating sustainable and clean energy.

废水中包含的化学能可被认为是有前途的可持续能源，可以使用微生物燃料电池技术通过电活性细菌进行回收。有几家啤酒工业将废水排放到环境中，造成了严重的环境问题。在本文中，我们展示了通过接种局部分离的微生物，使用双室MFC同时处理啤酒废水和生产生物电的方法。微生物与啤酒废渣（分别称为BSGB1和BSGB2），啤酒废水（BWGB3和BWGB4）和食品加工业废渣（FSGB5和FSGB6）隔离。总溶解固体（TDS），化学需氧量（COD），在通过局部分离的微生物处理啤酒废水之前和之后，测定其生化需氧量（BOD）。结果表明，从啤酒废渣中分离出的微生物优于从啤酒废渣和食品加工业废渣中分离出的细菌。最大功率密度为0.8 W / m分别使用合成啤酒厂和酿酒厂废水，用MFC分别接种了来自啤酒废渣中的局部分离的微生物后，产生了³和0.35 W / m ³的气体。COD的去除效率为79-83％，这表明本地分离的微生物可显着处理啤酒废水，同时产生可持续的清洁能源。
