Two efficient anthracene-degrading strains are isolated from pollution sludge collected from sewage treatment plant and identified by sequencing their 16S rDNA genes, one is Pseudomonas nitroreducens and the other is Bacillus sp.. The proper growth conditions of each bacterium was measured and presented for anthracene-degrading. The optimum growth condition is pH 7.5, 30°C. Biodegradation assays revealed that the degradation rates of two bacterial strains are 82.3% and 80.7% in 7 days. Respectively, the two bacteria had played important roles in the degradation of anthracene.
