Effects of Ball Milling, Ultrosonic or Hydrochloric Acid Treatment on the Microstructure and Enzymatic Deacetylation Efficiency of Chitin [PDF]
Shipin Kexue, 2023 Chitin is the second most abundant natural polysaccharide on Earth, which can be deacetylated to produce chitosan. However, due to the high crystallinity and poor solubility of chitin, its efficiency of enzymatic deacetylation is very low. To investigate

Chitin Deacetylases: Properties and Applications [PDF]
Marine Drugs, 2010 Chitin deacetylases, occurring in marine bacteria, several fungi and a few insects, catalyze the deacetylation of chitin, a structural biopolymer found in countless forms of marine life, fungal cell and spore walls as well as insect cuticle and peritrophic matrices.

Chitin Deacetylases: Structures, Specificities, and Biotech Applications [PDF]
Polymers, 2018 Depolymerization and de-N-acetylation of chitin by chitinases and deacetylases generates a series of derivatives including chitosans and chitooligosaccharides (COS), which are involved in molecular recognition events such as modulation of cell signaling and morphogenesis, immune responses, and host-pathogen interactions.

Polycistronic Expression System for Pichia pastoris Composed of Chitino- and Chitosanolytic Enzymes
Frontiers in Bioengineering and Biotechnology, 2021 Chitin is one of the most abundant biopolymers. Due to its recalcitrant nature and insolubility in accessible solvents, it is often considered waste and not a bioresource. The products of chitin modification such as chitosan and chitooligosaccharides are

Preparation of Defined Chitosan Oligosaccharides Using Chitin Deacetylases [PDF]
International Journal of Molecular Sciences, 2020 During the past decade, detailed studies using well-defined ‘second generation’ chitosans have amply proved that both their material properties and their biological activities are dependent on their molecular structure, in particular on their degree of polymerisation (DP) and their fraction of acetylation (FA). Recent evidence suggests that the pattern
