Co-metabolism for enhanced phenol degradation and bioelectricity generation in microbial fuel cell

Enhanced bioelectrochemical treatment of petroleum refinery wastewater with Labaneh whey as co-substrate

“…However, glucose removal was higher during the first peak and phenol degradation was higher during the second peak 31 . In another study by Shen et al, phenol co-metabolism was found to be efficient with acetate as co-substrate compared to other four substrates studied 53 . A dual chambered MFC using industrial acid mine drainage was treated effectively with municipal wastewater as co-substrate 54 .…”

Simultaneous wastewater treatment and energy harvesting in microbial fuel cells: an update on the biocatalysts

“…This could explain the enhanced removal efficiency and power generation performance in MFCs. 19 Each specie plays a specic role in a mixed-culture community, establishing synergy in pollutants degradation, electricity generation, and/or the protection of the community against harmful environmental conditions. 20 The possible mechanisms of removing pollutants in MFCs can be summarized as follows: when it comes to nitrogen removal, [21][22][23] ammonia is oxidized to nitrite and/or nitrate by nitrifying bacteria, such as Nitrosomonas sp., Aridibacter, Nitrospira, and Bacillus thuringiensis.…”

“…53 Shen et al found that with acetate as co-substrate, not only the electricity production capacity and the electron transfer efficiency in MFCS was enhanced, but also phenol degradation was promoted. 19 Besides, it was reported that using biodegradable organics as co-substrate could enhance bacterial metabolism and accelerate 2,4,6-trichlorophenol degradation. 46,54 The co-substrate also show the positive effect on the degradation of p-nitrophenol by the anode functional bacteria of the genera Corynebacterium, Comamonas, Chryseobacterium and Rhodococcus.…”

The Utility of Electrochemical Systems in Microbial Degradation of Polycyclic Aromatic Hydrocarbons: Discourse, Diversity and Design

“…The fermentation products, e.g., acetate and formate, are essential resources for both electroactive microbe and methanogen (Arends et al, 2014), thus there is struggle for existence. In the MFC degradation of phenol, EET relevant cytochrome c OmcA of anode microbes was significantly activated by the exogenous acetate (Shen et al, 2020), thus acetate could also be salient cosubstrate in PAH elimination. The acetate is also generated by PAH degradation and utilized by exoelectrogens, thus driving the PAH dissipation.…”
