TL;DR: In this article, applications of chitin and chitosan for biomaterials are discussed. But the authors focus on the application of Chitin in biomedical applications.

TL;DR: With a simple, three-step procedure, both chitinases and both beta-1,3-glucanases were purified to homogeneity from the same extract and showed differences in their pH optimum, specific activity, and pattern of products released from laminarin.
Abstract: Chitinase and β-1,-3-glucanase activities increased coordinately in pea (Pisum sativum L. cv “Dot”) pods during development and maturation and when immature pea pods were inoculated with compatible or incompatible strains of Fusarium solani or wounded or treated with chitosan or ethylene. Up to five major soluble, basic proteins accumulated in stressed immature pods and in maturing untreated pods. After separation of these proteins by chromatofocusing, an enzymic function could be assigned to four of them: two were chitinases and two were β-1,3-glucanases. The different molecular forms of chitinase and β-1,3-glucanase were differentially regulated. Chitinase Ch1 (mol wt 33,100) and β-1,3-glucanase G2 (mol wt 34,300) were strongly induced in immature tissue in response to the various stresses, while chitinase Ch2 (mol wt 36,200) and β-1,3-glucanase G1 (mol wt 33,500) accumulated during the course of maturation. With a simple, three-step procedure, both chitinases and both β-1,3-glucanases were purified to homogeneity from the same extract. The two chitinases were endochitinases. They differed in their pH optimum, in specific activity, in the pattern of products formed from [3H]chitin, as well as in their relative lysozyme activity. Similarly, the two β-1,3-glucanases were endoglucanases that showed differences in their pH optimum, specific activity, and pattern of products released from laminarin.

TL;DR: A procedure for preparing individualized chitin nanofibers 3-4 nm in cross-sectional width and at least a few microns in length was developed and the original crystal structure of beta-chitin is maintained, although crystallinity index decreases from 0.51 to 0.37 as a result of the nanofiber conversion.

TL;DR: New environment-friendly beads prepared by a simple produce process for removal and recovery of heavy metals are developed based on mainly complexation adsorption model as well as a affinity of hydroxyl groups of the materials on metals.

TL;DR: In this paper, the authors investigated the mechanisms that govern Cr(VI) and Cu(II) removal, and found an appropriate model for the kinetics of removal in a batch reactor.
