Lignocellulosic biomass, especially in the form of waste residues such as those produced in the agriculture and forestry industries, has garnered significant attention in recent years for the production of fuels and high added value chemicals. It is a sustainable and renewable source of carbon and hydrogen, and is therefore suitable to replace fossil resources, which has promoted the concept of the bio-refinery. Analogous to the conventional refinery, the bio-refinery seeks to fractionate the initial lignocellulosic feedstock into its main constituents: cellulose, hemicellulose, and lignin. Each one has unique chemistry, and therefore different chemical processes need to be developed for their efficient conversion to traditional and novel chemicals and fuels that will replace the fossil-derived ones.
The biochemical transformation of lignocellulosic biomass, employing enzymes and microorganisms found in nature and drawing inspiration from our ecosystem, is emerging as an important tool in bio-refinery technology. It has significant advantages, such as high selectivity and low production of toxic by-products, low energy requirements, and it requires water as a solvent and is therefore an extremely green process. However, significant challenges also need to be addressed. Enzymes are still expensive, efficient pretreatment of the biomass is needed in order to efficiently convert its fractions, and biochemical reactions can be slow, significantly increasing reactor sizes.
Nevertheless, the added value of fermentation processes is unequivocal. Fermentation can produce fuels in the form of alcohols, chemicals such as lactic and succinic acid that are the building blocks for novel polymers, phenols and phenol oligomers with targeted functionalities that are derived from lignin—the only renewable source of aromatic rings in abundance. Moreover, high added value products are especially interesting, such as food additives in the form of prebiotics and omega-3 fatty acids derived from microalgae or nanoparticles of lignin and cellulose, which are products with increased functionalities.
This Special Issue aims to highlight the emerging role of fermentation in the production of traditional and novel products and to underline the key challenges that arise in this demanding yet fulfilling research area.

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.
