  • Bacterial community in dioxin contaminated soil and mud samples from Danang airport was enumerated and studied for their potential degradation capability against three-ring compound carbazol. The cell number was determined on nutrient rich medium and on mineral medium supplemented with carbazol. It has been showed that number of cells presented in mud samples was significantly higher than in soil samples, in the range of 1 magnitude order. About 50% of the total cell number in each sample grown on the medium with carbazol. Analyzing 12 representative strains selectively isolated on the carbazol containing medium by using the ARDRA method with two endonucleases HaeIII and MspI showed that bacterial community at the studied areas was highly diversified. However non from these isolates...
