Oil contaminated soil was collected from Huangpu River-Yangtze River estuary wetland,with the aim of isolating oil-degrading microorganisms and evaluating their ability to degrade diesel.Three bacterial strains were discovered and identified by sequencing their 16S rDNA genes,two were Pseudomonas and one was Alcaligenes.The proper growth conditions of each bacterium were measured and presented for diesel biodegradation.Biodegradation assays revealed that the degradation rates of three bacterial strains were 42.5%,14.6% and 15.9% in 7 d respectively.They all play an important role on the nalkanes within the range of C16-C25 components of diesel.The results indicated that the oil-degraders can adapt to degrade diesel.The bacterial strains can be used in wetland diesel pollution control.
