The importance of microbial adaptation in the removal of environmental pollutants and in maintaining active microbial communities in impacted ecosystems is discussed using the biodegradation of p-nitrophenol and the volatilization of mercuric mercury as examples. A molecular mechanism of adaptation is suggested by enrichment of mercury resistance (mer) genes in some communities upon exposure to mercury.
以对硝基苯酚的生物降解和汞的挥发为例，讨论了微生物适应在去除环境污染物以及在受影响生态系统中维持活跃微生物群落方面的重要性。一些群落暴露于汞后，汞抗性（mer）基因富集，由此提出了一种适应的分子机制。
