Lignin is among the most abundant organic substances, and is produced by vascular plants. It is an irregular aliphatic–aromatic heteropolymer based on C6C3 monomeric units. Arising from radical chain reactions, its hydrolysis to afford such monomeric units is quite a difficult task, whereas its highly cross-linked nature makes it almost insoluble in the common solvents, unless it is more or less deeply altered in its native structure.
Therefore, lignin biosynthesis deserves attention in order to elucidate the exact mechanism(s) by which plants build this robust structural polymer, and to intervene by means of genetic engineering tools to modulate its physico-chemical and mechanical properties. This could open the way towards tailor-made lignins (and consequently, woods) whose features could be pre-determined to optimize the required performances once the timber has to be utilized.
For the pulp and paper industry, lignin should be removed to leave cellulose fibers. However, the various processes that are currently available are still awaiting a full optimization, in terms of both efficiency and environmental impact: huge amounts of aggressive reagents are required, together with harsh and energy-consuming treatments, and produce enormous quantities of high-impact wastes.
Biological (mainly enzymatic) and biomimetic treatments are promising but far from showing a reasonable efficiency, so they require further deep studies to substantially move ahead.
This Special Issue welcomes experimental studies and reviews describing new insights and/or encompassing the state-of-the-art in the fields of lignin biosynthesis and its regulation/modulation, improvements of delignification treatments (both chemical and biological/biomimetic), and new frontiers in lignin utilization—possibly after suitable modification—as a biomaterial and/or as a promising source of derived chemicals.

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 papers will be 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. Polymers is an international peer-reviewed open access semimonthly 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 2200 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.
