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 ...

Impact of Fe(III) (Oxyhydr)oxides Mineralogy on Iron Solubilization and Associated Microbial Communities

Frontiers in Microbiology, 2020
Iron-reducing bacteria (IRB) are strongly involved in Fe cycling in surface environments. Transformation of Fe and associated trace elements is strongly linked to the reactivity of various iron minerals.

Analysis of the heterogenous structural states of the hexameric ATPase PilU of the type IV pili from Vibrio cholerae

Protein Science, Volume 35, Issue 6, June 2026.
Abstract Type IV pili (T4P) mediate surface motility, host interactions, and DNA uptake through cycles of extension and retraction. While the primary retraction ATPase PilT has been extensively characterized, its homolog PilU remains less well understood despite being demonstrated as a PilT‐dependent retraction ATPase.

Two Modes of Riboflavin-Mediated Extracellular Electron Transfer in Geobacter uraniireducens

Frontiers in Microbiology, 2018
Anaerobes respire extracellular electron acceptors by extracellular electron transfer (EET). It is widely recognized that flavins can act as electron shuttles to facilitate this process. Flavin synthesis genes are widely distributed in Geobacter species.

Disentangling the syntrophic electron transfer mechanisms of Candidatus geobacter eutrophica through electrochemical stimulation and machine learning

Scientific Reports, 2021
Interspecies hydrogen transfer (IHT) and direct interspecies electron transfer (DIET) are two syntrophy models for methanogenesis. Their relative importance in methanogenic environments is still unclear. Our recent discovery of a novel species Candidatus

Long‐Term Management Shapes Soil Microbial Communities Primarily Through Modulating Soil Habitat Quality in Swiss Croplands

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT Soil microbial communities are key drivers of soil functioning in agricultural systems. Yet the relative influence of soil properties and cropping practices on their diversity remains insufficiently understood. We investigated 60 cropland sites in western Switzerland, covering a broad range of soil properties and cropping practices, to explore

Endogenous Versus Exogenous Redox‐Mediators in Anaerobic Bioelectrochemical Systems: A Comparative Study With Pseudomonas putida

ChemElectroChem, Volume 13, Issue 10, 19 May 2026.
A comparative study of endogenous and exogenous mediators for bioelectrochemical systems is conducted. Ferricyanide and phenazine‐1‐carboxylic acid are selected as representative compounds, and their electrochemical and physiological impacts on Pseudomonas putida under comparable bioelectrochemical conditions are systematically evaluated.

Optimizing Microbial Fuel Cell Efficiency Through a Designed Electrogenic Consortium to Remove Alkylbenzenes

ChemElectroChem, Volume 13, Issue 10, 19 May 2026.
A mangrove‐derived electrogenic microbial consortium was successfully acclimated to codegrade ethylbenzene and xylenes in a microbial fuel cell (MFC). Acclimation provided high degradation efficiencies (up to 97%) and improved energy recovery. The MFC reached voltage of 520 mV and power density of 63.4 mW m−2.

Impact of conductive magnetite nanoparticles and anode polarization on glucose fermentation

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 5, Page 1027-1034, May 2026.
Abstract BACKGROUND Electrically conductive materials and electrochemical stimulation strategies are increasingly explored to steer microbial fermentation towards desired metabolic outputs. These approaches also hold remarkable potential to couple wastewater treatment (WWT) to the production of value‐added compounds, in turn enhancing environmental ...

The Curious Case of CysE: Diversity and Distribution of Serine Acetyltransferases in Bacteria

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 5, Page 1092-1103, May 2026.
ABSTRACT Serine acetyltransferase (CysE) is a member of the left‐handed β‐helix family of acetyltransferases that catalyze the rate limiting step in de novo cysteine biosynthesis. There are two isoforms of CysE that differ in length, with the shorter isoform lacking approximately 76 amino acids at the N‐terminus of the protein from the serine ...
