摘　　要：There are two ways for microbes to exchange information with the environment:1 the signal molecules (including autoinduction signals) bind regulatory protein and activate transcription of target gene clusters that downstream the correspondive promoters;and 2 the regulatory protein receive signals from sensor. By these ways the microbes regulate their complex life process to adapt to the enviromment. The information communication include anti inhibition reaction and biodegradation of xenobiotics. To the latter there is a series of regulatory noises so that operator can make decision previously, change DNA structure, enhance transcription to the novel signals. So microbes can adapt themselves to the pollutants in molecular ecology.There are two ways for microbes to exchange information with the environment:1 the signal molecules (including autoinduction signals) bind regulatory protein and activate transcription of target gene clusters that downstream the correspondive promoters;and 2 the regulatory protein receive signals from sensor.
