Microbial biodegradation of environmental pollutants is a field of growing importance because of its potential use in bioremediation and biocatalysis. We have studied the characteristics of the global biodegradation network that is brought about by all the known chemical reactions that are implicated in this process, regardless of their microbial hosts. This combination produces an efficient and integrated suprametabolism, with properties similar to those that define metabolic networks in single organisms. The characteristics of this network support an evolutionary scenario in which the reactions evolved outwards from the central metabolism. The properties of the global biodegradation network have implications for predicting the fate of current and future environmental pollutants.
由于微生物对环境污染物的生物降解在生物修复和生物催化方面的潜在应用,该领域的重要性日益凸显。我们研究了由该过程中所有已知化学反应所构成的全球生物降解网络的特征,无论这些反应的微生物宿主是什么。这种组合产生了一种高效且整合的超代谢,其特性类似于定义单个生物体代谢网络的特性。该网络的特征支持一种进化情景,即反应从中心代谢向外演化。全球生物降解网络的特性对于预测当前和未来环境污染物的归宿具有重要意义。
