“…On the other hand, biological electrochemical systems have shown both good removal efficiencies and simultaneous energy generation to support wastewater treatment plants' operational costs. Previously, the removal efficiencies of the drugs such as cocaine and cannabinoid metabolites found in urine were examined in microbial electrochemical cells, and over 90% of removal rates were reported (Catal et al 2019;Ozdemir et al 2019). There results indicate that microbial electrolysis cells could be used to remove drugs found in urine providing a clean approach for wastewater treatment, and support the operation costs of the wastewater treatment plants generating hydrogen.…”

“…Studies using human urine containing metabolites as a substrate in microbial electrolysis cells have been reported previously. Microbial electrochemical cells can detect and remove metabolites in wastewater and also produce energy (Catal et al 2019;Ozdemir et al 2019). It was reported that hydrogen production in microbial electrolysis cells using sodium acetate, monosaccharaides, disaccharides and cellulosic wastes as carbon sources (Catal 2015;Catal et al 2015Catal et al , 2017.…”

In this study, hydrogen production was analyzed along with methane and carbon dioxide generation using paroxetine, venlafaxine, and o-desmethylvenlafaxine (ODV) as substrates in single-chamber microbial electrolysis cells (MECs). Combinations of all three drugs were examined at concentrations of 750 ng/mL and 170 ng/mL. At the beginning of MEC operations using a 750 ng/mL mixture of drugs, there was no hydrogen or methane, but carbon dioxide was detected. When the concentration of the drug mixture was reduced to 170 ng/mL, MECs produced hydrogen and methane gas. Removal of the drugs during MEC operations was also analyzed using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). Paroxetine, venlafaxine and ODV drugs were removed up to 99% by MECs. In conclusion, MECs could offer an alternative treatment method for wastewaters containing psychoactive pharmaceuticals with the added benefit of fuel hydrogen generation.

“…Single-chamber air-cathode MFCs were built as described previously. [42,43] Anode and cathode were made of carbon cloth (Lot: 14032102, FuelCells, Texas, USA, 7 cm 2 for anode and CTO32414, FuelCells, Texas, USA, 7 cm 2 for cathode) (Figure 1). MFCs with a volume of 12 mL were inoculated with 6 mL active sludge obtained from the local domestic wastewater treatment plant (Pasakoy, Advanced Biological Wastewater Treatment Plant, Istanbul, Turkey) supplemented with glucose (1 g L −1 ).…”

Antidepressants accumulate in the aquatic environment due to human wastes. “Here, microbial fuel cell (MFC) technology is investigated as a candidate for elimination of antidepressants introduced into environment via human wastewaters.” Human urine containing selective serotonin reuptake inhibitors (paroxetine) and serotonin‐norepinephrine reuptake inhibitors (venlafaxine, O‐desmethylvenlafaxine (ODV)) are used as substrates in MFCs. Electricity production by the MFCs is monitored while simultaneous drug degradation is analyzed using liquid chromatography‐tandem mass spectrometry. When the human urine samples containing drugs (10 or 50 ng drug per mL) are treated in MFCs, electricity production decreases in response to increasing drug concentrations. Upon addition of drugs‐containing urine, chemical oxygen demand removal capacity of MFCs decreases from 54% to 37%. Mass spectrometry results show that drugs are degraded at a rate of 10 ng mL−1 per hour for paroxetine, 11 ng mL−1 per hour for venlafaxine, and 16 ng mL−1 per hour for ODV, i.e., 94% of paroxetine, 66% of venlafaxine, and 48% of ODV is cleared in 9 h of treatment. In conclusion, MFC exhibits great potential in elimination of paroxetine, venlafaxine, and ODV from wastewater. These results can help to develop sustainable strategies to combat antidepressant pollution.

“…[4][5][6] Microbial electrolysis cells (MECs) are biotechnological tools that have the capability to use microorganisms as biocatalysts to obtain hydrogen energy from chemical energy stored in organic substances including lignocellulosic materials. 1,7,8 MECs open a new gate to provide hydrogen energy in the world. MECs also give a chance to generate hydrogen as a final product, and wastewaters can be bioremediated through this technology.…”

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.
