[Isolation and identification of two marine bacteria with hydrocarbon-biodegradation activity].
Two bacterial strains, able to degrade both diesel fuel and PAHs, were isolated from the oil sewage of oil storage dock in Xiamen. Analysis of 16S rDNA sequences showed that both strains had high homology (99%) with Pseudomonas stutzeri and should be classified to this species. But Biolog analysis showed they were quite different strains. Tests of temperature, salinity, pH on cell growth suggested that they were from marine environment. Both showed high degradation activity to naphthalene, 87.53% and 84.01% within 3 days; and slight activity to pyrene, 8.35% and 5.37% within 7 days. And both harbored naphthalene dioxygenase genes of 98% identity with other those from Pseudomonas strains.
