Abstract
As the human activities increasing, pesticide, oil and heavy metal used widely caused the environmental pollution more and more serious. Therefore, it is very necessary to find the reasonable and efficient method to degrade environmental pollutants. This article summarized the construction of genetic engineering bacteria and its applications in pesticide pollution, oil pollution and heavy metal pollution bioremediation, which has proved to be a hot pot in environmental pollutants bioremediation researching. It also put forward the difficulties in the construction and application of genetic engineering bacteria and developing trend.
