Abstract
In order to effectively repair groundwater pollution and remove petroleum hydrocarbons, two petroleum hydrocarbon degrading bacteria SYT-1 and SYT-2 were isolated from long-term petroleum hydrocarbon contaminated groundwater. The rescreening experiments showed that the degradation rates of SYT-1 and SYT-2 were 65.16 % and 52.52 %, respectively. SYT-1 and SYT-2 were identified as Moraxella and Acinetobacter. The degrading bacteria SYT-1 and SYT-2 were identified as Moxa and Acinetobacter by physiological and biochemical characteristics and 16S rDNA sequencing. The experimental results provide strain resources and technical support for bioremediation of petroleum pollution in groundwater.
