Special Issue Information

Dear Colleagues,

Biomass constitutes an abundant and renewable carbon resource that can be processed to produce many valuable products, platform chemicals, biofuels, and energy. As an alternative to fossil feedstocks, the utilization of biomass as raw material to obtain carbon-based end products offers the benefits of a sustainable chemical industry and mitigate greenhouse gas emissions.

Existing biomass conversion processes include chemical, thermochemical, catalytic, and enzymatic treatments. Current societal needs and transition towards a circular economy place a focus on the utilization of biomass wastes and residues as raw material. In turn, waste processing poses a significant challenge, requiring the development of novel conversion routes and/or the intensification of existing ones before they become economically viable.

In this Special Issue we welcome both original research and review papers dealing with novel materials derived from biomass waste, as well as works concerned with conversion optimization strategies and modeling. Papers dealing with technologies for the catalytic conversion of lignocellulosic biomass feedstocks into fuels and chemicals are encouraged. Papers describing novel routes for the upgrading of easily obtained biomass-derived molecules (e.g., levulinic acid, furanics, lactones) into advanced biofuels and chemicals are also valuable. 

You may choose our Joint Special Issue in Materials.

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. Processes 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 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.

Rapeseed meal (RM) is produced in large quantities as a byproduct of oil extraction from rapeseeds. However, the efficient utilization of RM as animal feed is limited by its low metabolizable energy, poor palatability, and high levels of fiber and anti-nutritional components. Here, we investigate the potential of enriching RM with single-cell protein through fermentation with conventional and unconventional yeasts. The process of simultaneous saccharification and fermentation improved the parameters of the waste biomass, especially the protein content, while reducing the amount of crude fiber and enhancing the biotransformation of isoflavone compounds present in the waste. Fermentation yielded the highest protein gain for the Saccharomyces cerevisiae Ethanol Red strain (ΔN = 2.38%) at a biomass load of 12.5 g and for Scheffersomyces stipitis (ΔN = 2.34%) at an enzyme dose of 0.125 mL/10 g DM. The crude fiber content (CF) was reduced by 2.55–7.18%. The simultaneous saccharification and fermentation (SSF) process resulted in the conversion of isoflavones to forms with fewer adverse effects and a lower estrogenic activity. The results show the potential of using RM as a substrate for making a nutritionally improved feed components. Full article
