Fundamental Aspects of Extracellular Electron Transfer Processes

Dear Colleagues,

Extracellular electron transfer (EET) is a metabolic capability displayed by numerous microorganisms that enables them to colonize and grow in diverse environments where soluble electron acceptors and donors are limited. Using EET, these microorganisms can exchange electrons with extracellular solid compounds, including metal minerals (e.g. iron and manganese oxides) in their natural environment, or conductive materials, such as electrodes, in artificial bioelectrochemical systems. In the last two decades, this microbial activity has received considerable attention for several biotechnological applications, including bioremediation of environmental sites contaminated with toxic metals, production of electricity, bioelectrosynthesis of industrially valuable commodities and wastewater treatment. Understanding the mechanisms of EET is crucial, not only to understand the impact of these organisms in the global biogeochemical cycles of metals, in particular of iron, but also to apply them in sustainable biotechnological processes.

The scope of this special issue is to cover the fundamental aspects of EET processes, in particular the molecular mechanisms by which microorganisms exchange electrons with extracellular solid compounds. Reviews and Original Research articles are welcome. Emphasis will be made on manuscripts that focus on microorganisms that perform EET, molecular aspects of their EET pathways, and on the fundamental knowledge of the microbial EET metabolism.

Manuscripts can be submitted now or up until the deadline. All papers will go through peer-review process. Accepted papers will be published in the journal (as soon as accepted) and meanwhile listed together on the special issue website. Research articles, reviews as well as short communications are preferred. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office to announce on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts will be thoroughly refereed through a double-blind peer-review process. Please visit the Instruction for Authors page before submitting a manuscript. The Article Processing Charge (APC) in this open access journal is 2500 USD. Submitted manuscripts should be well formatted in good English.
