“…Mevastatin removal through traditional wastewater treatment methods was reported to be as low as 34%. 46 Our results suggest that significant amount of mevastatin up to 95% could be removed in MECs. Since the type of substrates used as the carbon source in MECs significantly affect the bioactivity and hydrogen generation performance, 47 the removal and biodegradation of toxic pharmaceuticals including mevastatin could be enhanced using optimized substrates in future.…”

Mevastatin is one of the common pharmaceuticals found in wastewaters, and its biodegradation is still an environmental problem due to its recalcitrant properties. Although various biological, chemical and physical methods have been investigated for the removal of mevastin, microbial electrolysis cells (MECs) have not been examined, yet. MECs are new generation biotechnological tools used in hydrogen energy production. In this study, the effects of mevastatin on hydrogen production in MECs were investigated for the first time. MECs produced hydrogen gas in the presence of mevastatin, and an increase in hydrogen production was observed. Over 90% of the mevastatin were removed in MECs. These results also showed that the fermentation process associated with carbon dioxide production can favor hydrogen production with mevastatin. In conclusion, the efficiency of hydrogen production in microbial cells can be increased by the use of wastewaters contaminated with mevastatin.

“…It was reported that 60-70% of clofibric acid and more than 75% of bezafibrate and gemfibrozil were removed [31]. Due to its recalcitrant nature, however, mevastatin elimination via conventional wastewater treatment was reported to be as low as 34% [32]. Using MFCs, however, we were able to demonstrate almost complete removal of mevastatin.…”

Mevastatin is one of the pollutants in wastewater that is difficult to biodegrade. In this study, the issue of mevastatin biodegradation and simultaneous electricity generation using microbial fuel cells, which is one of the current sustainable technologies, was investigated. Effects of mevastatin on the performance of single-chamber air-cathode microbial fuel cells were investigated. On average, 0.2 volts of electricity was generated in microbial fuel cells in the presence of 5.6 µM mevastatin, while mevastatin caused an important increase in coulombic efficiency, from 35±5% to 49±8. More than 90% of the mevastatin was removed in microbial fuel cells in approximately four days. In conclusion, mevastatin that causes toxicity in wastewaters could potentially be treated using microbial fuel cells. Meanwhile, mevastatin may enhance electricity generation either through improved electron transfer or suppressed methanogenesis during microbial fuel cell operations.

“…Among the several substrates, wastewater is a resource-rich medium that MFCs may handle. Several reports have been published on the direct generation of electricity from complex organic wastewater, including municipal, swine wastewater, dairy wastewater, slaughterhouse wastewater, rice mill wastewater, tannery wastewater, cassava mill wastewater, molasses wastewater, refinery wastewater, brewery wastewater, winery wastewater, chemical wastewater, sulfide-rich wastewater, landfill leachate, food waste leachate, azo dye, and solid substrates such as rice straw [ 49 , 50 , 51 , 52 ]. MFCs can also simultaneously remove sulfide and nitrate from synthetic wastewater and sulfate–sulfide-rich wastewaters [ 53 ].…”

Due to the continuous depletion of natural resources currently used for electricity generation, it is imperative to develop alternative energy sources. Human waste is nowadays being explored as an efficient source to produce bio-energy. Human waste is renewable and can be used as a source for an uninterrupted energy supply in bioelectricity or biofuel. Annually, human waste such as urine is produced in trillions of liters globally. Hence, utilizing the waste to produce bioenergy is bio-economically suitable and ecologically balanced. Microbial fuel cells (MFCs) play a crucial role in providing an effective mode of bioelectricity production by implementing the role of transducers. MFCs convert organic matter into energy using bio-electro-oxidation of material to produce electricity. Over the years, MFCs have been explored prominently in various fields to find a backup for providing bioenergy and biofuel. MFCs involve the role of exoelectrogens which work as transducers to convert the material into electricity by catalyzing redox reactions. This review paper demonstrates how human waste is useful for producing electricity and how this innovation would be beneficial in the long term, considering the current scenario of increasing demand for the supply of products and shortages of natural resources used to produce biofuel and bioelectricity.
