Evaluation of Glucosamine Hydrochloride from Biowaste of Macrobrachium rosenbergii and Penaeus monodon in Different Ponds of Andhra Pradesh, India

A variety of goods made from the skeletons of crustaceans have both biomedical and pharmacological abilities. As an amino monosaccharide that serves as a substrate for the synthesis of aggrecan and proteoglycans, glucosamine has therapeutic potential for osteoarthritis. The goal of the current work is to produce glucosamine hydrochloride (Glu-HCl) by acid hydrolysis from a variety of crustacean shells, specifically Macrobrachium rosenbergii and Penaeus monodon (tiger shrimp), and then quantify the result using reversed phase high performance liquid chromatography (RP-HPLC). The fiber found in crab, lobster, shrimp, and prawns is called chitin. Chitosan, a naturally occurring biopolymer, was created by deacetylating chitin, one of the main structural components that make up the exoskeleton of crustaceans. Chitosan is a linear polymer of a (1–4)-linked 2-amino 2-deoxy b-D glucopyranose. Shell trash is produced in large quantities by the aqua industry and is typically dumped, causing significant environmental nuisance. Glucosamine hydrochloride, chitin, and chitosan can all be obtained commercially from such waste. In this study, the yield % of the tiger shrimp (Penaeus monodon) and freshwater prawn (Macrobrachium rosenbergii) is being assessed. In comparison to P. monodon, M. rosenbergii was a superior producer. The recycling of crustacean waste into a product with added value is also covered in this study.
