For a successful transition to a sustainable bio-based society and a circular economy, it is of primary interest to implement processes that recover bioproducts and biofuels from renewable raw materials. In the modern discipline of environmental engineering, anaerobic fermentation technology has been widely employed for the valorization of food wastes, municipal sewage sludge, animal manure and agricultural residues, as well as various industrial wastewaters. Anaerobic methanogenic fermentation is performed by a synergic microbial consortium in four sequential steps (hydrolysis, acidogenesis, acetogenesis and methanogenesis) where the products of one step are used as substrate for the following step. This bioprocess can be performed in the conventional way, where the four steps end up in methane-rich biogas production, or can be applied to produce high-added-value soluble metabolite products such as ethanol, lactate, short-chain fatty acids and hydrogen-rich biogas in a shortened process called dark fermentation. Soluble metabolite products derived from hydrolysis/acidogenesis steps are considered valuable building blocks for the chemical industry and can be a product by themselves, or can serve as precursors for a wide variety of bioproducts (alcohols, aldehydes, ketones, elongated- to medium-chain fatty acids, etc.), which entails applications in various areas, including the production of solvents, adhesives, food additives, cosmetics and pharmaceuticals. Secondly, hydrogen has a high energy density and is currently being considered as an alternative environmentally friendly gas fuel of the future, which will reduce dependence on fossil fuels and effectively initiate a new energy transition.
Although anaerobic fermentation is a well-established bioprocess for the transformation of raw materials into biogas, further research is needed to overcome its limitations regarding process efficiency, product synthesis, and effective resource utilization. Therefore, this Special Issue of Fermentation aims to publish innovative original articles and comprehensive reviews on various aspects of anaerobic fermentation for obtaining high-value bioproducts, in order to contribute to maximizing resource and energy recovery from organic waste and creating a new platform to establish sustainable biorefineries.

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.
