    Influence of Fe2+ and Fe3+ on the Performance and Microbial Community Composition of a MFC Inoculated with Sulfate-Reducing Sludge and Acetate as Electron Donor by José Roberto González-Paz, María del Carmen Monterrubio–Badillo, Alberto Ordaz, E. Inés García-Peña, Claudia Guerrero-Barajas

    Published 2022-01-01
    “…In general, the metabolic activity of the MFC supplemented with Fe2+ was higher than the system with Fe3+ reaching a percentage of sulfate reduction (% SR), sulfide concentration (mg/L HS-), and removal of chemical oxygen demand (% COD removal) of 35.2±0.75, 450.3±3.6, and 50.05±0.24 for % SR, HS-, and % COD, respectively, whereas in the MFC with Fe3+, the percentages were of 30.1±1.076, 220.6±2.0, and 11.78±10.81 for % SR, HS-, and % COD, respectively. The microbial population determined in each system was also correlated to the metabolic activity. …”
