Abstract
To investigate the performance of microbial fuel cell (MFC) with a single-chamber membrane, Pseudomonas aeruginosa is used as a bio catalyst for various synthetic wastewaters rich in carbohydrate and is compared with real dairy wastewater in this experiment. Therefore, the choice of appropriate carbon, nitrogen, NaCl, inoculum content, temperature, and pH process parameters are used for preparing synthetic wastewater was agreed upon by one-variable-at-a time approach. Maximum levels of voltage generation attained from the synthetic wastewater was 485 mV when supplemented with 1.5 % of lactose as a source of carbon, 0.3 % of ammonium chloride as a decent nitrogen source, 0.03 % of NaCl, inoculum concentration of 3 %, the temperature at 37 oC and pH 7. On the other hand, the maximum voltage attained with real dairy wastewater was 561 mV with high chemical oxygen demand (COD) value of 801 mg l-1. The maximum power density obtained from dairy wastewater was 73.54 mW m-2. Thus, High voltage achieved for MFC operating with real dairy wastewater suggests that it can be used not only for the industrial application to generate more renewable power, but also for the wastewater treatment carried out at the same time.

IntroductionWASTEWATERS IN MICROBIAL FUEL CELL sources like coal, oil, and petrol [1]
The conducted experiments showed that the microbial fuel cells (MFC) batch process is an active procedure for the workable generation of sustainable power by exoelectrogenic bacteria (Pseudomonas aeruginosa)
The batch process examined for 360 hours (15 days) with one-variable-at-a-time optimized synthetic wastewater media containing lactose of 1.5 %, ammonium chloride of 0.3 %, 0.03 % of NaCl, inoculum concentration of 3 %, temperature at 37 °C and pH 7, generated OCV of 485 mV
Summary
WASTEWATERS IN MICROBIAL FUEL CELL sources like coal, oil, and petrol [1]. In previous couple of decades, people had consistently used non-renewable energy sources and utilized them for power generation [2]. As they belong to the conventional sources of energy, they are exhaustible [3] and are getting depleted at an alarming rate. Microbial fuel cell technology is gaining more attention for industrial applications and attaining more power at a large scale [5]. The utility of the energy from microbial fuel cells (MFC) is significant to keep attention on their production [6]. The performance of MFC can be increased by changing the physicochemical parameters and these days, research with MFC is achieving more attention [7]
