Abstract An organism,identified as Rhodococcus sp.EBT-2,was isolated from the slurry in Dagang Oil Field of Tianjin,China.Analysis of HPLC revealed that EBT-2 could desulfurize DBT to 2-hydroxybiphenyl(2-HBP) selectively.Furthermore,the effects of temperature,initial pH,carbon source and nitrate source on the growth and capacity of removal DBT were investigated.Results showed that the suitable inital pH is 7.5,temperature is 30 ℃,the best carbon source and nitrate source are glucose and ammonium chloride.Under optimum operating conditions,DBT of 0.25 mmol/L was degraded to 0.03 mmol/L by growing cells of EBT-2 within 48 h,simultaneously producing 2-HBP of 0.19 mmol/L.
