There is accumulating evidence that motile bacteria are chemotactically attracted to environmental pollutants that they can degrade. Chemotaxis, the ability of motile bacteria to detect and respond to specific chemicals in the environment, can increase an organism's chances of locating useful sources of carbon, nitrogen and energy, and could thus play an important role in the biodegradation process. Recent evidence demonstrating that chemotaxis and biodegradation genes are coordinately regulated suggests that these processes are intimately linked in nature.
越来越多的证据表明,运动性细菌会被它们能够降解的环境污染物吸引,并产生趋化作用。趋化作用是指运动性细菌检测并响应环境中特定化学物质的能力,它可以增加生物体找到碳、氮和能量有用来源的机会,因此可能在生物降解过程中发挥重要作用。最近有证据表明,趋化作用和生物降解基因受到协同调控,这表明这些过程在自然界中紧密相连。
