In India export of processed and frozen shell products is that the backbone of the seafood export industry. The waste generated from the worldwide production and process of shellfish could be a significant issue of growing magnitude and could be a threat to the surroundings. Particularly the assembly and consumption of crustaceans like crabs, mussels, and prawns have enhanced within recent years, thereby generating an outsized quantity of solid shell waste. It is essential to convert shell waste into helpful products like chitin, chitosan, etc., by recycle and reducing the waste additionally as contribute towards profitable work and economic advantages. Chitosan is created from chitin by a chemical change involving demineralization (DM), deproteinization (DP), and deacetylation (DA). This research aims to comparative study was undertaken to extract chitosan from some crustacean shells ( Scylla serrate (mud crab), litopenaeus setiferus (white shrimp) and modiolus modiolus (horse mussel), wastes) and were subjected to physicochemical properties are moisture, ash, yields, degree of deacetylation, water, and fat binding capability were additionally determined. The active biomolecules like chitin and its derivatives undergoing a major and really quick development in the food application space. Therefore the current investigation is geared toward the usage of different shell waste by using it to work the bactericide activity against medically necessary pathogens. Finally, the tested materials were determined through disc diffusion technique against 3 strains of Gram-negative microorganism (Escherichia coli; Klebsiella pneumonia, and Pseudomonas aeruginosa) and 2 Gram-positive bacteria (Bacillus subtilis; staphylococcus aureus). This study suggests that Scylla serrate may well be used as a supply of a high amount of chitosan than litopenaeus setiferus and modiolus modiolus and it is an advantage for elaborated studies. Hence, this treatment is effective for realizing recent bioactive compounds from natural sources which can enhance the invention and development of recent drugs. Our study conjointly pointed to the chance of using chitosan as a natural supply of bactericide compounds.
