Special Issue Information

Dear Colleagues,

Enzymes are able to catalyze numerous reaction pathways while achieving a high reaction specificity under mild conditions. Enzymatic reactions are thus believed to minimize the requirement of hazardous materials and the formation of byproducts, thus contributing to development of sustainable reaction routes. Target substrates and the resulting products in enzymatic conversion are currently expanding because of attempts to connect green and sustainable chemistry principles to conventional chemical reactions, which represents a great source of challenges in several research & development areas. The fact that new enzymes are continuously discovered as advanced techniques on cultivation, heterogeneous gene expression, and metagenomics are continuously developed also encourages deployment of the enzymes for chemical transformation. Beyond the use of native enzymes, in-depth understanding of enzymes structures, functions, and kinetics allows for sophisticated engineering of enzyme activity and ultimately leads to bulk production of several genetically modified enzymes. Adjuvant agents such as immobilization materials and enzyme mediator systems have made enzymatic conversion more attractive in terms of product efficiency and enzyme recyclability. This Special Issue seeks original articles, case studies, and review papers in topics that include but are not limited to the following:

  • Enzymatic conversion;
  • Whole-cell-based bioconversion;
  • Enzyme-mediator systems;
  • Enzyme immobilization;
  • Organic synthesis with enzymes;
  • Xenobiotic transformation with enzymes;
  • Novel enzymatic (or whole-cell-based) activity for chemical transformation.

Thank you for your contributions.

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. Sustainability 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 2400 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.

Tons of anthropological activities contribute daily to the massive amount of lignocellulosic wastes produced annually. Unfortunately, their full potential usually is underutilized, and most of the biomass ends up in landfills. Lignocellulolytic enzymes are vital and central to developing an economical, environmentally friendly, and sustainable biological method for pre-treatment and degradation of lignocellulosic biomass which can lead to the release of essential end products such as enzymes, organic acids, chemicals, feed, and biofuel. Sustainable degradation of lignocellulosic biomass via hydrolysis is achievable by lignocellulolytic enzymes, which can be used in various applications, including but not limited to biofuel production, the textile industry, waste treatment, the food and drink industry, personal care industry, health and pharmaceutical industries. Nevertheless, for this to materialize, feasible steps to overcome the high cost of pre-treatment and lower operational costs such as handling, storage, and transportation of lignocellulose waste need to be deployed. Insight on lignocellulolytic enzymes and how they can be exploited industrially will help develop novel processes that will reduce cost and improve the adoption of biomass, which is more advantageous. This review focuses on lignocellulases, their use in the sustainable conversion of waste biomass to produce valued-end products, and challenges impeding their adoption. Full article
