The untreated liquid waste generated from tannery industries have managed to take away the calmness and serenity from our hectic and tensed lives by tampering our greatest wealth i.e. health. It has also degraded our environment at a fanatic pace. Moreover, with rapid industrialisation under the guise of automation, modernization and progress have also contaminated our water bodies as the untreated effluent are release directly into them, therefore leading to a catastrophic impact on the quality of water and aquatic life. The present study being first of its kind investigate the impact of different solvent extract of marine algae Sargassum on the various physicochemical parameters like TDS, hardness, chloride, nitrate, sulphate and chromium (VI) of tannery industry effluent. Phytochemical analysis of various solvent extract namely SET, SMT, SCT, SBT and SAT were performed and the retentate was used as biofertilizer for growth of Vigna mungo. The length and protein content of the plant showed a significant increase in comparison to the control. With the help of Imvic test, the organism isolated from tannery industry effluent was identified as Pseudomonas (MIC 1800 mg/l for Cr (VI)). Methanolic extract of Sargassum was found to be most effective in improving the quality of water and removal of toxic metals like Cr (VI).
