Innovative genomics and metagenomics of environmental bacteria able to degrade organic pollutants

环境细菌能够降解各种顽固性和外源化合物，在有机污染物的去除中起着重要作用。为了了解这些细菌在其原生生态位中的生存和增殖策略，我们在基因组水平上利用两个系统发育遥远的菌株鉴定了对土壤环境中生存和特异性诱导非常重要的遗传位点。宏基因组分析还阐明了土壤中细菌种群对有机污染物暴露的反应模式。

Environmental bacteria able to degrade various recalcitrant and xenobiotic compounds play important roles in the removal of organic pollutants. To know the survival and proliferation strategies of such bacteria in their native niche, the genetic loci very important in the survival and specifically induced in the soil environment were identified at the genomic levels using two phylogentically distant strains. Metagenomic analysis was also conducted to clarify the mode how the bacterial population in the soil responded to the exposure of organic pollutants.
