Bio-Electro-Fermentation towards Circular Bioeconomy and Sustainable Development

Dear Colleagues,

Fermentation technologies have been gaining traction in many contexts including waste valorization, high-value chemical production, waste to energy conversion and environmental remediation. While the field of fermentation covers a wide range of scientific principles and processes, the advancement of fermentation technology is hindered by a few main factors such as its economic feasibility, process limitations, and long-term sustainability. This Special Issue will cover the latest advances and breakthroughs in understanding some of the underlying working principles of fermentation, especially electrofermentation technologies and their role towards circular bioeconomy and sustainable development. Research articles that investigate the circularity and life cycle impacts of various fermentation processes in various agricultural, industrial, and municipal applications are encouraged. Case studies demonstrating the feasibility and long-term sustainability of fermentation processes in the production of high-value market chemicals, high-energy-density fuels including avaiation fuels, and waste valorization products are welcome. Mechanistic studies addressing process limitations and scale-up challenges will be considered. Studies focusing on modeling and integrated system analysis in terms of sustainable development goals and circular bioeconomy are of particular interest.

Topics of interest include but are not limited to:

1. High-value chemical production through various fermentation processes;
2. Circular economy of electrofermentation;
3. CO₂ valorization through electrofermentation;
4. Sustainable bioproducts (biofuels and chemicals) through electrofermentation;
5. LCA of electrofermentation technologies;
6. Scale up and commercialization aspects of electrofermentation technologies;
7. Elucidation of underlying mechanisms/processes involved in electrofermentation;
8. Integration of conventional fermentation–electrofermentation technologies;
9. Hydrogen production under dark conditions and with electrofermentation;
10. Microbiome studies focusing on process optimization and stability.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fermentation is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
