Horizontal Transfer of Environmental Pollutant-Degrading Gene and Application in Bioremediation

ZHANG Rui-Fu, JIANG Jian-Dong, DAI Xian-Zhu, GU Li-Feng, LI Shun-Peng(Key Laboratory of Microbiological Engineering Agricultural Environment, Ministry of Agriculture, Nanjing Agricultural University, Nanjing 210095, China)  
Horizontal gene transfer, unlike vertical gene transfer, is a means of genetic communication in bacteria. In the special polluted environment, horizontal transfer of pollutant-degrading gene has significant functions. Study on horizontal transfer of degrading gene in polluted environment may deepen our understanding of the mechanism of bacterial adaptation to the organic-polluted environments, the environmental toxicity and bioavailability of pollutants, and the bioremediation of polluted environment. In the practical application in bioremediation, horizontal transfer of degrading gene can be regulated to promote degrading ability of microorganisms. In this article, we will review the advances in the study on mechanisms of genetic interactions among bacteria, the effect of degrading gene transfer in contaminated environment on microorganisms' adaptation to contaminated environment and the degradation of the pollutants.
