A microbial consortium isolated from Shengli oilfield polluted sludge was capable of degrading naphthalene (NAP), phenanthrene (PHE), pyrene (PYR) and crude oil. It performed high biodegradation activity and emulsifiability for petroleum hydrocarbons, and was tolerant to 6.2mM Cu(2+), 2.7 mM Zn(2+) and 9.5mM Pb(2+). Biodegradation rates of NAP, PHE, PYR and crude oil were 53%, 21%, 32% and 44% in the presence of heavy metal (Cu(2+), 1.7 mM and Zn(2+), 2mM), respectively. Exploration on the… CONTINUE READING
