Abstract

The purpose of present microcosmic study was to investigate the degradation of major PAHs of petroleum sludge i.e. Pyrene (4 aromatic rings) by petroleum hydrocarbon degrading bacteria isolated from petroleum sludge collected from Barauni Oil Refinery; Begusari, Bihar (India). Changes in pH, bacterial biomass and their protein amount were also observed during the degradation of selected Pyrene (100 ppm). The outcome of this microbiological work can be used for research on remediation of petroleum-contaminated environments.
