Structure and function of a broad-specificity chitin deacetylase from Aspergillus nidulans FGSC A4

Scientific Reports, 2017
Enzymatic conversion of chitin, a β-1,4 linked polymer of N-acetylglucosamine, is of major interest in areas varying from the biorefining of chitin-rich waste streams to understanding how medically relevant fungi remodel their chitin-containing cell ...

Enantioselective organocatalysis with size-defined chitosan oligomers

, 2014
Des oligomères de taille définie de chitosane ont été préparés et testés en tant qu'organocatalyseurs dans des réactions d'aldolisation énantiosélectives. Les précurseurs de ces catalyseurs sont obtenus en une seule étape par une réaction d'acétolyse contrôlée de la chitine, second polysaccharide le plus abondant.

Selective acylation of chitosan oligomers by several cyclic anhydrides as a 13C NMR quantification method

Carbohydrate Polymer Technologies and Applications
The chemistry of chitosan is a promising way to afford biobased and biodegradable complex materials using highly reactive compounds such as anhydrides. However, the potential applications are limited due to the absence of control over the acylation and ...

Continuous production of chitooligosaccharides in a column reactor by the PUF-immobilized whole cell enzymes of Mucor circinelloides IBT-83

Microbial Cell Factories
Background Chitosan oligosaccharides (COS) have great potential for applications in several fields, including agriculture, food industry or medicine. Nevertheless, the large-scale use of COS requires the development of cost-effective technologies for ...
