Chitin dissolved in N,N-dimethylacetamide, N-methyl-2-pyrrolidone and their mixed solvents in the presence of 5% LiCl was treated with acetic anhydride-pyridine, and the mixture solution was heated at 100 degrees C for 6 h to give a partially O-acetylated chitin gel. Chitin dissolved in these solvents in the presence of 5% LiCl was mixed with pyridine,

Abstract Natural Resources Chitin is a biopolymer found in crustaceans shells (crab, shrimp, prawn, lobster) in some mollusks (krill, oyster, clam shells, squid skeleton). It is also found in fungi (mushrooms, yeast) and in various insects (cockroaches, silkworms, spiders, beetles).

Shrimp chitin as substrate for fungal chitin deacetylase
Applied Microbiology and Biotechnology, 2001The fungal chitin deacetylases (CDA) studied so far are able to perform heterogeneous enzymatic deacetylation on their solid substrate, but only to a limited extent. Kinetic data show that about 5-10% of the N-acetyl glucosamine residues are deacetylated rapidly. Thereafter enzymatic deacetylation is slow.

Enzymatic degradation of chitins and partially deacetylated chitins
International Journal of Biological Macromolecules, 1994The enzymatic (lysozyme, chitinase etc.) digestibility of chitins obtained from squid pen and shrimp shell, and of partially deacetylated chitins (DA-chitins) was investigated. The digestibility of various chitins by the chitinase from Bacillus sp. PI-7S was much higher than that by lysozyme, and beta-chitin was digested more smoothly than alpha-chitin.

Chitin Biotechnology Applications
1996This review article describes the current status of the production and consumption of chitin and chitosan, and their current practical applications in biotechnology with some attempted uses. The applications include: 1) cationic agents for polluted waste-water treatment, 2) agricultural materials, 3) food and feed additives, 4) hypocholesterolemic ...

Chitin solutions and purification of chitin
1988Publisher Summary This chapter describes the dissolution and purification of chitin isolates via the newer anhydrous media. There is no clear line of demarcation between chitin isolation and its purification, but the isolation method affects chitin quality and in part determines any additional dissolution and other purification steps required.
