Biological treatment of phenol has gained wide interest owing to its advantages of complete phenol mineralization and cost effectiveness. Phenol degradation capabilities of bacteria and fungi have been profoundly studied compared to that in algae. Six algal strains were screened for phenol degradation ability of which Spirogyra, Closterium and two unidentified algae were isolated from sewage wastewater, one diatom strain BD1IITG was isolated from petroleum refinery wastewater and Chlorella Pyrenoidosa (NCIM 2738) was obtained from National Collection of Industrial Microorganisms, Pune.enPhenolBiodegradationAlgaeBiodiesel FeedstockPathwayPhenol HydroxylaseThesis
