Innovative Biotechnological Production of Microbial Polysaccharides

Dear Colleagues,

Microbial polysaccharides synthesized by various microorganisms, including bacteria, yeasts, microalgae, and fungi are complex carbohydrates that exhibit remarkable structural diversity and play a central role in microbial physiology and environmental interactions. Their unique chemical compositions and physical and functional properties make them valuable resources for many industrial applications, as food additives, cosmetic ingredients, pharmaceutical and nutraceutical bioactive compounds, nanocarriers, and biomaterials. Taking advantage of the metabolic capabilities of microbial strains, fermentation processes provide efficient and sustainable ways to produce these polysaccharides with complex structures and unlock the full potential of microbial polysaccharides for industrial and biomedical applications.

This Special Issue is dedicated to exploring advances and cutting-edge challenges in the production of microbial polysaccharides and sharing the latest discoveries, methodologies, and research results. It welcomes all kinds of contributions (original research articles, reviews, and perspectives) that explore various aspects of microbial polysaccharide production, including but not limited to the following:

• Novel microbial strains and their growth optimization for improving polysaccharide synthesis.
• Characterization, purification, and functionalization of microbial polysaccharides for industrial applications.
• Advances in fermentation techniques and bioprocess engineering to improve the production and yield of polysaccharides.
• Exploration of metabolic pathways and genetic engineering strategies to tailor polysaccharide characteristics.
• Bioreactor design and scale-up strategies for industrial-scale production.
• Implementation of AI for optimizations and production control.
• Innovative sustainable approaches to produce polysaccharides, including raw material selection, waste use, and eco-friendly production practices.

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. 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.
