Outline of Final Research Achievements

Environmental microbial communities play very important roles in the bioremediation of chemical pollutants. Analysis of a phenanthrene-degrading bacterial consortium in this study showed that such degradation ability of a strain is enhanced by other co-residing and non-degrading strains through two types of mechanisms. Furthermore, transplantation of bacterial community to independent and sterilized environmental samples resulted in very similar time-course changes in the community compositions, indicating the validity of such transplantation to obtain reproducible information on bacterial degradation of chemical pollutants in natural environments.
