Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...

In Vivo Molecular Insights into Syntrophic Geobacter Aggregates

, 2020
Direct interspecies electron transfer (DIET) has been considered as a novel and highly efficient strategy in both natural anaerobic environments and artificial microbial fuel cells. A syntrophic model consisting of Geobacter metallireducens and Geobacter

Cytochromes in Extracellular Electron Transfer in Geobacter [PDF]

Applied and Environmental Microbiology, 2021
Extracellular electron transfer (EET) is an important biological process in microbial physiology as found in dissimilatory metal oxidation/reduction and interspecies electron transfer in syntrophy in natural environments. EET also plays a critical role in microorganisms relevant to environmental biotechnology in metal-contaminated areas ...

Relative Resiliency of Bioanode Electrochemical Resistances with Changes in Interelectrode Spacing in Microbial Electrolysis Cells

ChemElectroChem, Volume 13, Issue 13, 2 July 2026.
Hydrogen gas can be produced from organic matter in microbial electrolysis cells (MECS) using certain microorganisms on the anode and a catalyst on the cathode. We show that materials and different electrode distances change gas production rates, but the intrinsic properties of the microbes to produce current were unaffected by subsequent changes in ...

Construction of a Geobacter Strain With Exceptional Growth on Cathodes [PDF]

Frontiers in Microbiology, 2018
Insoluble extracellular electron donors are important sources of energy for anaerobic respiration in biogeochemical cycling and in diverse practical applications. The previous lack of a genetically tractable model microorganism that could be grown to high densities under anaerobic conditions in pure culture with an insoluble extracellular electron ...
