Study on the Extraction and Characterization of Polymer (chitosan) Obtained from Scales of Channa striatus, Exoskeleton of Barytelphusa guerini, Macrobrachium rosenbergii and Fresh Water Mussel from Fresh Water Bodies of Madhya pardesh

Abstract

Background: The most prevalent naturally occurring amino polysaccharide is chitosan. Chitosan’s biocompatibility biodegradability and non-toxicity have led to its wide spread use in the pharmaceutical industry according to research. The biopolymer chitosan is typically extracted from the crustacean shells such as, Crab, Prawn, Lobster, fish scales etc. Methods: The research was accomplished during 2021-2022 to examine the extraction and characterization of chitosan (polymer) from four different organism of fresh water i.e fish scales, bivalve, prawn and crab shells. Extracted chitosan has been produced by using various parameters i.e. demineralization deproteinization and deacetylation as chemical methods. Result: Results showed that chitosan was found maximum in the crab (Bareytelphusa guerini) 87.29% followed by Prawn (Macrobrachium rosenbergii) and scales of fish (Channa striatus) which have an average yield (38.55% and 32.56%) respectively and (18.14%)which is lowest yield among all obtained from fresh water mussel (bivalve). The chitosan extracted from the samples were characterized by Fourier transform infrared spectroscopy (FTIR) and existence of chitosan was confirmed and best yield of chitosan was obtained from Bareytelphusa guerini.
