Exoskeleton of prawn was powdered and subjected for sequential treatment process including deproteinization, demineralization and decolorization to obtain chitin in a colorless white powder form. The obtained chitin was subjected for deacetylation to obtain chitosan. The resultant biogenic chitosan was subjected for antibacterial and antifungal activity. Chitosan exhibited significant activity against Escherichia coli and Aspergillus niger. Free radical scavenging activity of chitosan gradually increased with increase in the concentration of chitosan. Antioxidant activity of prawn shell chitosan was found to be maximized at the concentration of 500 μl/ml.
