Visualizing Microbial Indirect Extracellular Electron Transfer

Environmental Science & Technology
Indirect extracellular electron transfer (IEET) mediated by soluble electron shuttles is a critical pathway for anaerobic microbial respiration, influencing redox transformations and element cycling in natural environments. However, direct spatial visualization of the electron transfer extent has remained limited.

Nanomaterials Facilitating Microbial Extracellular Electron Transfer at Interfaces

Advanced Materials, 2020
AbstractElectrochemically active bacteria can transport their metabolically generated electrons to anodes, or accept electrons from cathodes to synthesize high‐value chemicals and fuels, via a process known as extracellular electron transfer (EET). Harnessing of this microbial EET process has led to the development of microbial bio‐electrochemical ...

Humic Substances and Extracellular Electron Transfer

2012
Humic substances (HS) are redox-active organic molecules that are present in virtually all environments. A wide variety of bacteria including Fe(III)-reducers, sulfate reducers, methanogens, and fermenting bacteria can reduce HS and in a second, abiotic step, the reduced HS can transfer their electrons to terminal electron acceptors such as poorly ...

Extracellular electron transfer mechanisms between microorganisms and minerals

Nature Reviews Microbiology, 2016
Electrons can be transferred from microorganisms to multivalent metal ions that are associated with minerals and vice versa. As the microbial cell envelope is neither physically permeable to minerals nor electrically conductive, microorganisms have evolved strategies to exchange electrons with extracellular minerals.

On the Role of Endogenous Electron Shuttles in Extracellular Electron Transfer

2012
As a result of cellular metabolism, microbes dramatically alter the chemistry of environments in which they live. Microbes directly influence cycling of metals in the environment via respiratory redox transformations, often influencing solubility and toxicity of these metals by altering their redox state.

Bacterial extracellular electron transfer in bioelectrochemical systems

Process Biochemistry, 2012
Abstract Bioelectrochemical systems (BES), typically microbial fuel cells (MFCs), have attracted increasing attention in the past decade due to their promising applications in many fields, such as bioremediation, energy generation and biosynthesis. Current-generating microorganisms play a key role in BES.

Extracellular Electron Transfer in Methanogenic Archaea

2019
Three decades ago, respiration with a solid electron donor or acceptor would have made great science fiction. Now we know that “electroactive” microorganisms perform this on a daily basis in various anaerobic habitats. These electroactive microorganisms are classified by their ability to utilize solid electron donors or acceptors outside of the cell in
