Response of soil microbial community to exposure of environmental pollutants

Soil microbial communities play very important role in the bioremediation of chemical pollutants. To investigate how such a community responded to and degrade the pollutants, time series analysis of the community in an artificially polluted and closed soil system was carried out by metagenomic sequencing of the community in conjunction with the isolation and characterization of the genes and bacterial strains able to degrade the pollutants. Our analysis strongly suggested the crucial catabolic genes and their host genera involved in the bioremediation in the polluted soil.
