“…Chang et al [51] reported that the maximum power density (PD) and coulombic efficiency (CE) of about 162.74 mW/m 2 and 7.09% were recorded after 8 h of HRT (hydraulic retention time) by MFC (plain-graphite plate) during pharmaceutical wastewater treatment containing PPs. They also revealed that the total PD and CE production decreased to 29.12 mW/m 2 and 2.23% respectively after 5 h HRT in sewage water.…”

“…The increase in HRT increases the efficiency of COD and coulombic efficiency (CE) (You et al 2006;Haavisto et al 2017) because the volumetric organic loading rate rises (Sobieszuk et al 2017). Furthermore, the increasing time leads to increased pollutant removal efficiency such as total nitrogen (TN), ammonium, nitrate, COD, pharmaceutical products (Li et al 2013b;Ma et al 2016;Chang et al 2018).…”

Environmental and economic considerations suggest a more efficient and comprehensive use of biomass for bioenergy production. One of the most attractive technologies is the microbial fuel cell using the catabolic activity of microorganisms to generate electricity from organic matter. Microbial fuel cell (MFC) has operational benefits and higher performance than current technologies for producing energy from organic materials because they convert electricity from the substrate directly (at ambient temperature). However, MFCs are still not suitable for high energy demand due to practical limitations. The overall performance of an MFC depends on the electrode material, the reactor design, the operating parameters, substrates, and microorganisms. Furthermore, the optimization of the parameters will lead to the commercial development of this technology in the near future. The simultaneous effect of the parameters on each other (intensifier or attenuator) has also been investigated. The investigated parameters in this study include temperature, pH, flow Rate & hydraulic retention time, mode, external resistance, and initial concentration.

“…Sixteen microbial genera (Arthrobacter, Rhizobium, Azospirillum, Sphingomonas, Azoarcus, Paenibacillus, Pseudomonas, Achromobacter, Hydrogenophaga, Thauera, Enterobacter, Janthinobacterium, Cupriavidus, Massilia, Bacillus and Magnetospirillum) were detected in all of the sediments supplemented with NaNO 3 or Na 2 SO 4 . Four of the sixteen microbial genera (Bacillus, Hydrogenophaga, Pseudomonas and Sphingomonas) have been reported to be associated with ACE (and paracetamol compounds) degradation [14,[35][36][37]. These results suggested that sixteen microbial genera may be involved in anaerobic ACE degradation in the sediments supplemented with NaNO 3 or Na 2 SO 4 .…”

Acetaminophen (ACE) is a widely used medicine. Currently, concerns regarding its potential adverse effects on the environments are raised. The aim of this study was to evaluate ACE biodegradation in mangrove sediments under aerobic and anaerobic conditions. Three ACE biodegradation strategies in mangrove sediments were tested. The degradation half-lives (t1/2) of ACE in the sediments with spent mushroom compost under aerobic conditions ranged from 3.24 ± 0.16 to 6.25 ± 0.31 d. The degradation half-lives (t1/2) of ACE in sediments with isolated bacterial strains ranged from 2.54 ± 0.13 to 3.30 ± 0.17 d and from 2.62 ± 0.13 to 3.52 ± 0.17 d under aerobic and anaerobic conditions, respectively. The degradation half-lives (t1/2) of ACE in sediments amended with NaNO3, Na2SO4 and NaHCO3 under anaerobic conditions ranged from 1.16 ± 0.06 to 3.05 ± 0.15 d, 2.39 ± 0.12 to 3.84 ± 0.19 d and 2.79 ± 0.14 to 10.75 ± 0.53 d, respectively. The addition of the three electron acceptors enhanced ACE degradation in mangrove sediments, where NaNO3 yielded the best effects. Sixteen microbial genera were identified as the major members of microbial communities associated in anaerobic ACE degradation in mangrove sediments with addition of NaNO3 and Na2SO4. Three (Arthrobacter, Enterobacter and Bacillus) of the sixteen microbial genera were identified in the isolated ACE-degrading bacterial strains.
