Efficacy of chitinases from mangrove wetland derived Penicillium oxalicum on powdered chitin [PDF]

Frontiers in Microbiology
Chitin, an abundant polysaccharide in shrimp and crab shells, serves as a primary resource for producing glucosamine and chitosan oligosaccharides. Chemical hydrolysis is widely utilized in these processes, due to the limited efficacy of many chitinases ...

Crustacean shell waste derived chitin and chitin nanomaterials for application in agriculture, food, and health – A review

Carbohydrate Polymer Technologies and Applications, 2023
Chitin, a widely available natural polymer, is the fundamental structural component of crustacean shells. The crustacean processing industry produces a lot of shell waste each year (in millions), most of which is discarded and poses serious environmental

Extraction and characterization of chitin from granary weevil, Sitophilus granaries L. (Coleoptera: Curculionidae) [PDF]

Arthropods, 2022
Insect chitin has been extracted from granary weevil - Sitophilus granarius L, commonly called wheat weevil in laboratory by treating it with 1 M HCl and 1 M NaOH. This was followed by decolorization. The yield of chitin from this species is 20.2%.

Chitin-induced systemic disease resistance in rice requires both OsCERK1 and OsCEBiP and is mediated via perturbation of cell-wall biogenesis in leaves

Frontiers in Plant Science, 2022
Chitin is a well-known elicitor of disease resistance and its recognition by plants is crucial to perceive fungal infections. Chitin can induce both a local immune response and a systemic disease resistance when provided as a supplement in soils.
