Study on the Physicochemical Properties of Chitosan and their Applications in the Biomedical Sector

International Journal of Polymer Science, Volume 2023, Issue 1, 2023., 2023
Chitosan is a natural polymer derived from the deacetylation of chitin. It is mainly derived from crustaceans and fungal sources. It has many intrinsic properties, such as biocompatibility, biodegradability, cationic nature, and nontoxicity. These features of chitosan have made it an attractive material for various applications.

Rim Pathway-Mediated Alterations in the Fungal Cell Wall Influence Immune Recognition and Inflammation

mBio, 2017
Compared to other fungal pathogens, Cryptococcus neoformans is particularly adept at avoiding detection by innate immune cells. To explore fungal cellular features involved in immune avoidance, we characterized cell surface changes of the C.

Rational protein design of Bacillus sp. MN chitosanase for altered substrate binding and production of specific chitosan oligomers

Journal of Biological Engineering, 2019
Background Partially acetylated chito-oligosaccharides (paCOS) have a variety of potential applications in different fields, but to harness their benefits, pure paCOS or well-defined paCOS mixtures are essential.

A polysaccharide deacetylase from Puccinia striiformis f. sp. tritici is an important pathogenicity gene that suppresses plant immunity

Plant Biotechnology Journal, Volume 18, Issue 8, Page 1830-1842, August 2020., 2020
Summary The cell wall of filamentous fungi, comprised of chitin, polysaccharide and glycoproteins, maintains the integrity of hyphae and protect them from defence responses by potential host plants. Here, we report that one polysaccharide deacetylase of Puccinia striiformis f. sp.

Expanding the substrate scope of chitooligosaccharide oxidase from Fusarium graminearum by structure-inspired mutagenesis [PDF]

, 2015
Chitooligosaccharide oxidase from Fusarium graminearum (ChitO) oxidizes N-acetyl-D-glucosamine (GlcNAc) and its oligomers with high efficiency at the C1-hydroxyl moiety while it shows poor or no activity with other carbohydrates.

Microbial Valorization of Chitinous Bioresources for Chitin Extraction and Production of Chito-Oligomers and N-Acetylglucosamine: Trends, Perspectives and Prospects

, 2018
Chitin, the crystalline polymer of N-acetylglucosamine (GlcNAc) is the world’s second most abundant carbohydrate and principal structural component of cell wall of fungi, yeasts and algae, insect exoskeletons, shells of crustaceans and the microfilarial sheath of nematodes. GlcNAc is present in peptidoglycan, hyaluronic acid and keratin sulfate.

The plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

iMeta, Volume 5, Issue 4, August 2026.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial
