Polysaccharides from Marine Environments II

Dear Colleagues,

Seas and oceans cover around 71 % of Earth and hold 96.5 % of the planet’s water. Even if marine organisms represent more than 25% of the Earth’s species, they are one of the most underutilized biological resources. Indeed, macroalgae, microalgae, bacteria, and animals from this environment are known to produce large quantities of polysaccharides, making them very attractive for bioprospecting and potential exploitation as commercial sources of these biopolymers. Polysaccharides exhibit a wide variety of biochemical structures based on combinations of up to 40 different monosaccharides. This extreme diversity of glycosidically linked structures provides an extensive group of biopolymers, with complex architectures associated with specific biological or rheological properties. Moreover, some marine polysaccharides harbor specific structural features such as sulfate groups or a cationic character, making them very attractive for industrial applications. Success stories involving new marine polysaccharides in the field of pharmaceutic, nutraceutic, cosmetic, and biosourced materials, and others, have recently been reported. All these successes are a consequence of the increasing knowledge in the identification of marine polysaccharide producers, the characterization of these macromolecules, the development of processes for their extraction, and the analysis of their properties. This Special Issue provides recent reviews and research articles in the field of marine polysaccharides.

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. Applied Sciences 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.
