2 Napthalene Sulfonate (2NS), Biodegradation, Genotoxicity


Present study aimed to treat 2 Napthalene Sulfonate (2NS), a dye intermediate with microbial consortia and assess its potential toxicological impact before and after treatment on the integrity of Deoxyribo-Nucleic Acid (DNA) in blood cells of Channa punctatus. Symbolic elevation in DNA damage with untreated 2NS administered fishes was observed as revealed by comet assay and micronucleus test. However, 2NS after being degraded using mixed bacterial population showed significant reduction in toxicological effects of 2NS. Thus, this study not only illustrated the adverse impact of such toxic contaminant of industrial waste but also suggested a highly efficient and eco-friendly way to remove the harmful xenobiotics from the environment which may help to reduce the exposure of aquatic fauna and flora to such lethal toxicants.
