Abstract

Phenol, an organic compound, is very toxic upon ingestion, contact or inhalation and is lethal to living organism even at low concentration. Phenolic compounds are present in varying concentration in waste water of synthetic resins, plastic and polymer manufacturing, dye and dye intermediate manufacturing and pharmaceutical industries. Among various techniques available for removing phenol biological treatment has been proved to be economical and most promising and versatile approach. The present investigation was under taken to assess the biodegradation of phenol by native bacterial strain from effluent from phenol contaminated site of Amla Khadi, Ankleshwar. A selected, Gram positive, bacterial strain so isolated, has been used to study biodegradation of phenol in shake flask culture. Various physicochemical parameters are optimized for the maximum biodegradation of phenol, viz., pH, temperature, initial concentration of phenol, additional carbon sources and additional nitrogen sources. Complete phenol biodegradation was achieved after 4 days in 1000 ppm solution. The isolated Gram positive bacterium can be exploited as a candidate of choice for the bioremediation of phenolic effluent.
