Dear Colleagues,

Applied biocatalytic processes play a growing role in global material and energy cycles. To date, it is yet to be determined how the diversity of biocatalysts employed in laboratory scale experimentation of energy conversion systems and resource recovery processes will affect the future bioeconomy. Nevertheless, current attempts and advances to integrate biocatalysts with distributed energy systems and developing biorefineries, as well as to combine disciplines such as bioelectrochemistry, process engineering, and power/waste-to-x technologies, are plentiful and outline a promising path to follow.

Among these, the development of tools enabling a cleaner and more efficient exploitation of organic wastes, sewage sludge, or lignocellulosic biomass, as well as harnessing alternative catalytic systems from renewable resources are exciting directions that call for further research activity.

In this Special Issue, we aim to highlight the most recent innovations in biocatalytic approaches for advanced energy conversion and biomass valorization. This includes, but is clearly not limited to, microbial or enzymatic processes that facilitate (i) usage and storage of excess renewable electricity as biofuels or value-added chemicals; (ii) sustainable and distributed power generation; (iii) resource bio-recovery from waste streams. We are looking forward to discussing the chances offered by sustainably sourced catalysts and bioreactor components, and accomplishments in the field of biocatalytic tool development.

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. Catalysts 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 2700 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.
