Abstract

Fish waste is considered to be one of the major bio-pollutants which are generally discarded in coastal regions through local markets and fish processing industries. Nowadays, it is being eyed as a newer Bio-resource and few of the bio-products commercially marketed are oil, bioactive peptides, collagen, chitosan and gelatin. In the present study we have used fish scales waste generated through local market to synthesize chitosan nanoparticles. Antimicrobial activity for different pathogens like staphylococcus aureus, Salmonella, Vibrio cholera, V. parahaemolyticus, E. coli, was performed out of these V. cholera, E. coli showed a zone formation of 30 mm. Antioxidant assay various concentration of 20-100 was performed and the scavenging activity of the sample is calculated as 11%. Haemolytic activity using goat�s blood is done in various concentration 101-108 activity showed is the haemolysis or the RBC break down is noted only from the 106 where as each cell carries the 2n amount of haemolysis thus the factor is 26=64 Hu (haemolytic units). Further characterization of chitosan nanoparticles was performed using SEM and FT-IR. Treating the obtained bio-products with effluent obtained from the fish processing industries is studied. The pH and turbidity of the effluent was measured by checking the BOD and COD after treating the effluent with the immobilized chitosan nanoparticles. The highest flocculation efficiency of chitosan observed under these conditions was 80% COD removal and 90% of turbidity removal.
