Geobacter sulfurreducens Extracellular Multiheme Cytochrome PgcA Facilitates Respiration to Fe(III) Oxides But Not Electrodes

Frontiers in Microbiology, 2017
Extracellular cytochromes are hypothesized to facilitate the final steps of electron transfer between the outer membrane of the metal-reducing bacterium Geobacter sulfurreducens and solid-phase electron acceptors such as metal oxides and electrode ...

Extracellular electron uptake in Methanosarcinales is independent of multiheme c -type cytochromes [PDF]

Scientific Reports, 2019
Abstract The co-occurrence of Geobacter and Methanosarcinales is often used as a proxy for the manifestation of direct interspecies electron transfer (DIET) in man-made and natural aquatic environments. We previously reported that not all

The modular evolution of multiheme cytochromes c bucks the general trend observed in most proteins

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Multiheme cytochromes c are versatile enzymes which contribute to key steps in diverse biogeochemical cycles of chemical elements such as nitrogen, iron, and sulfur, and are also key players in microbial electrochemical technologies. Understanding how they evolved offers a blueprint on how nature tuned their sequence and heme c cofactors to ...

Advancing the Resolution of the Sulfur Compound Disproportionation Puzzle in Dissulfuribacter Thermophilus S69ᵀ Through Quantitative Label‐Free Comparative Proteomics

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
To date, only three microorganisms have been functionally characterised for sulfur disproportionation. Our work identifies a fourth example and provides novel proteomic insights into its underlying pathways. These findings advance our understanding of microbial sulfur catabolism and highlight the ecological role of D.

Rational Design of Covalent Multiheme Cytochrome‐Carbon Dot Biohybrids for Photoinduced Electron Transfer

Advanced Functional Materials, 2023
AbstractBiohybrid systems can combine inorganic light‐harvesting materials and whole‐cell biocatalysts to utilize solar energy for the production of chemicals and fuels. Whole‐cell biocatalysts have an intrinsic self‐repair ability and are able to produce a wide variety of multicarbon chemicals in a sustainable way with metabolic engineering.

Structure of Geobacter OmcZ filaments suggests extracellular cytochrome polymers evolved independently multiple times

eLife, 2022
While early genetic and low-resolution structural observations suggested that extracellular conductive filaments on metal-reducing organisms such as Geobacter were composed of type IV pili, it has now been established that bacterial c-type cytochromes ...

Three Decades of Soil N2O Research—Insights and Gaps

Global Change Biology, Volume 32, Issue 8, August 2026.
Progress in N2O Research and Key Breakthroughs and Transitions from 1990 to 2025 across three domains: (A) process understanding, (B) microbial ecology, and (C) modelling of soil N2O emissions. ABSTRACT Nitrous oxide (N2O) is a potent greenhouse gas (GHG) whose atmospheric concentration continues to rise, largely driven by nitrogen (N) inputs to ...

Biomethane Energy Production Using Orange Hydrogen Coupled With CO2 Sequestration and Utilization

Carbon Neutralization, Volume 5, Issue 4, July 2026.
In subsurface hydrocarbon‐simulated environments, injected CO2 follows dual transformation routes: geochemical mineralization into stable carbonates (CCS) and microbially mediated conversion into CH4 energy through anaerobic metabolic processes. ABSTRACT The escalating concerns of global warming have intensified the global demand for clean energy ...
