Abstract

Abstract: : A bacterial strain with high ability of nickel resistance and petroleum-degrading was isolated from the soil of heavily-polluted areas around the shale gas wells in Changning-Weiyuan，Sichuan Province，and its biological characteristics and physiological-biochemical indexes were studied. The seed liquid was inoculated into the liquid medium containing heavy metal and crude oil，cultured at 30℃ and 130 r/min for 7 days to explore the resistance of the strain to nickel ions（Ni²⁺）and the rate of degrading total petroleum hydrocarbon（TPH）. Further，the strain was identified based on the experimental results of physiology and biochemistry，morphological observation and 16S rDNA sequences. As results，the tolerance of the strain to Ni²⁺ reached 300 mg/L，and the removal rate and adsorption rate of Ni²⁺ reached 56.64% and 52.16%，respectively; meanwhile，the degradation rate of TPH reached 35.65%. The species of the strain belonged to Citrobacter（Citrobacter sp.）and named Citrobacter farmeri strain M1. The optimal growth temperature of this strain was 30℃，the optimal growth pH was from 7 to 9，the optimal C∶N was 10∶1，and the maximum salt tolerance was up to 5%. In conclusion，solid nickel resistance and petroleum degradability of the strain contributes to its applicability in the remediation of heavy metal and oil-contaminated soil.

Key words: petroleum-degrading bacterium, nickel resistance, isolation and identification, biological characteristic
