Special Issue Information

Dear Colleagues,

Filamentous fungi are well known for their ability to produce organic acids, primary and secondary metabolites, enzymes and other proteins with applications in many industrial fields, including food and feed, pulp and paper, detergent, textile, pharmaceutical or biochemical and biofuel industries, among others. Industrial strains are commonly obtained by classical (non-GMO) strategies. However, in the last decades, genetic engineering—including genome editing—has contributed enormously to the development of efficient production strains with several potential applications in industry.

This Special Issue will be dedicated to any type of study (research articles, reviews, brief reports, etc.) that addresses the improvement of filamentous fungi, either through classical or biotechnological techniques, aimed at developing and optimization of filamentous fungal strains for their application at the industrial level. We also welcome papers describing methodologies for the genomic modification of industrially relevant fungal strains.

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. Journal of Fungi 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.

Valorization of agri-food residues has garnered significant interest for obtaining value-added compounds such as enzymes or bioactive molecules. Rice milling by-products, such as rice bran, have limited commercial value and may pose environmental challenges. Filamentous fungi are recognized for their ability to grow on residues and for their capacity to produce large amounts of metabolites and enzymes of industrial interest. Here, we used filamentous fungi to produce enzyme cocktails from rice bran, which, due to its polysaccharide composition, serves as an ideal substrate for the growth of fungi producing cellulases and xylanases. To this end, sixteen fungal strains were isolated from rice bran and identified at the species level. The species belonged to the genera Aspergillus, Penicillium, and Mucor. The Aspergillus species displayed the highest efficiency in cellulase and xylanase activities, especially A. niger var. phoenicis and A. amstelodami. A. terreus, A. tritici, and A. montevidensis stood out as xylanolytic isolates, while P. parvofructum exhibited good cellulase activity. A. niger var. phoenicis followed by A. terreus showed the highest specific enzymatic activities of α- and β-D-galactosidase, α-L-arabinofuranosidase, α- and β-D-glucosidase, and β-D-xylosidase. Additionally, proteomic analysis of A. terreus, A. niger var. phoenicis, and P. parvofructum exoproteomes revealed differences in enzyme production for rice bran degradation. A. niger var. phoenicis had the highest levels of xylanases and cellulases, while P. parvofructum excelled in proteases, starch-degrading enzymes, and antifungal proteins. Finally, two Penicillium isolates were notable as producers of up to three different antifungal proteins. Our results demonstrate that filamentous fungi can effectively valorize rice bran by producing enzyme cocktails of industrial interest, along with bioactive peptides, in a cost-efficient manner, aligning with the circular bio-economy framework.
