Extraction and Physicochemical Characterization of Chitin from Phalangium opilio Linnaeus, 1758 (Arachnida: Opiliones)



Chitin is a biomaterial which has a high potential of use in many areas of technology. It is found as a structural material in the outer skeletons of arthropods, the cell walls of mushrooms and the shells of marine invertebrates. It is also the second most abundant biopolymer in nature after cellulose. But when considered the biopolymers with nitrogen in their structure, chitin is the most abundant biopolymer. In recent years, apart from crustaceans and mushrooms, of arachnids, corals and crustacean eggs and even bat guanosu have been proposed as alternative chitin sources. In this study, it was firstly extracted chitin from external skeleton of an opilionid species, Phalangium opilio Linnaeus, 1758, and the isolated chitin was characterized by FTIR, SEM, TGA and XRD. The obtained chitin has been found to have high thermal stability, nanofiber and nanoporous surface and alpha form, and it is suggested that it can be an alternative chitin source.
