Reductive degradation of chloramphenicol using bioelectrochemical system (BES): A comparative study of abiotic cathode and biocathode

Effect of temperature switchover on the degradation of antibiotic chloramphenicol by biocathode bioelectrochemical system

“…Microbial transformation of glucose (which served as the intracellular electron donor and growth carbon source for cathodophilic microbes) releases electrons, which could be used by cathodophilic microbes for the enhancement of CAP and nitrobenzene reduction Sun et al, 2013;Wang et al, 2011). At 25°C, the biocathode reactors (divided into two groups) had the same trends for the efficiencies of glucose transformation and VFA as well as ethanol production (1-6 cycles in Fig.…”

“…The BES has been applied for cathodic reduction of diverse pollutants (Huang et al, 2011;Rosenbaum et al, 2011), particularly for the reduction of nitroaromatic pollutants (Li et al, 2010;Liang et al, 2013Liang et al, , 2014Mu et al, 2009;Shen et al, 2012;Sun et al, 2012;Wang et al, 2011Wang et al, , 2012. Bioelectrochemical degradation of CAP by biocathodes and abiotic cathodes was recently studied Sun et al, 2013). In general, environmental temperatures vary daily, especially in winter, or at high latitudes and in hilly regions.…”

Cometabolic degradation of chloramphenicol via a meta-cleavage pathway in a microbial fuel cell and its microbial community

“…Bioelectrochemical systems (BESs), including microbial fuel cells (MFCs) and microbial electrolysis cells (MECs) with biocatalyzed electrodes, can be used to degrade various pollutants (e.g., transforming nitroaromatics) into amino-aromatic compounds and to remove antibiotics such as sulfamethoxazole, ceftriaxone and ampicillin (Körbahti and Tas ßyürek, 2015;Liang et al, 2014;Wang et al, 2016;Wen et al, 2011). Biocatalytic electrochemical cells have also been used to degrade CAP using an external voltage and glucose as the electron donor (Sun et al, 2013). Unlike MECs, MFCs do not require an external input voltage and consume less energy.…”

“…Various physicochemical methods have been used to investigate CAP degradation, such as photocatalytic reduction, zerovalent bimetallic nanoparticles, and the Fenton process (Sun et al, 2013). However, most of these methods consume energy and/or chemicals.…”

Response of antimicrobial nitrofurazone-degrading biocathode communities to different cathode potentials

“…Bioelectrochemical systems (BES), employing electrochemically active microorganisms to catalyze oxidative or reductive reactions in the anode or cathode respectively, have attracted a considerable amount of attentions in recent decades (Pandey et al, 2016;Pant et al, 2010;Wang et al, 2015;Yun et al, 2017a), especially its merits on the bioelectrodegradation of various organic pollutants including nitro-, azo-, halo-aromatics and antimicrobial agents based on the microbial electrode-respiration process (Cui et al, 2014Feng et al, 2015;Gao et al, 2016;Jiang et al, 2016a;Li et al, 2016;Liang et al, 2013;Sun et al, 2013;Wang et al, 2011Wang et al, , 2016Zhang et al, 2017). Generally, operational factors could impact the catalytic efficiency and functioning stability of abiotic cathode/biocathode reactors (e.g.…”
