Results The two OHCB species in the defined consortia 22CO-6+PY97S and JZ9B+PY97S exhibited strong syntrophic effects in the oil biodegradation process. And the degradation rates of oil were increased from 27.81% and 83.52% to 64.03% and 86.89%, respectively. The consortia could degrade aliphatic and aromatic fraction at the same time, including high molecular weight-PAHs chrysene and its alkyl derivatives.
