Effects of long-term and incremental exposure to toxic pollutants on the current generation and microbial communities of electrochemically active bacteria

“…This result establishes a foundation to utilize MFCs for toxic wastewater treatment, e.g., petrochemical wastewater and garbage leachate. 25 Additionally, the main adaptive mechanism for mix-cultured microflora to cope toxic pollutants may be due to the dynamic shift in the microbial community and the enrichment of resistant bacteria. 21,22,26,27 Therefore, we hypothesize that long-term toxic exposure may induce an adaptive bacterial response in EAB and enrich resistant EAB, but the detailed changes in the EAB community should be further revealed.…”

“…This observation suggests that the same toxic exposure has similar effects on EAB communities, while the effects differ between different toxic exposures. 25,29 To provide clearer illustration of the differences in the EAB community among these samples, data dimensionality reduction analysis was employed. As depicted in Fig.…”

Effect of Electrode Spacing on the Performance of a Membrane-Less Microbial Fuel Cell with Magnetite as an Additive

“…In an MFC, in the same way as with other power generators, the main aim is to optimize the output power [ 42 ]. The power density is affected by electrode spacing [ 43 ]. From Figure 5 , all MFC digesters first showed an increase in power density, reached a maximum power density, and lastly showed a decrease in power density.…”

Electric current generation through the Wickerhamomyces anomalus yeast

“…Las CCM s contienen una serie de componentes que cumplen funciones específicas para su correcto funcionamiento, entre ellas se encuentra el compartimento anódico, el cual alberga el ánodo y el sustrato que es sometido a un tratamiento por parte de los microorganismos, generando electrones que viajan al compartimento catódico, siendo este último el cual alberga el cátodo, el sistema de catalizador catódico y el oxidante, asimismo las CCM cuentan con otros componentes como por ejemplo los catalizadores anódicos, los catalizadores catódicos, los electrolitos, los combustibles, los microorganismos y el sistema de transporte de electrones [1]. Dentro de este contexto cabe mencionar que las CCM presentan diversas configuraciones entre las más conocidas se encuentran las CCM de cámara simple, las CCM de doble cámara y las CCM cilindro [3].…”
