Treatment of Tannery Effluent by Pentachlorophenol-Degrading Bacterial Community from the Chemostat

摘要

A mixed microbial community enriched in a chemostat in presence of pentachlorophcnol (PCP) as sole source of carbon and energy comprised four bacterial strains, identified as Pseudomonas sp. (one strain) and Serralia marcescens (three strains). The bacterial community applied for the treatment of tannery effluent in a suspended culture and sequential bioreactor indicated the reduction of Chemical Oxygen Demand (COD) (68 per cent), sulphide (50 per cent), total phenol (78 per cent), and penlachlorophenol (65 per cent) in sequential bioreactor.
