硫（S）、氮（N）和氧（O）杂环是最强的环境污染物之一。微生物降解这些污染物是一种环境友好的生物过程，因此受到越来越多的关注。正在研究这些过程的生物技术潜力，例如，通过具有磁铁矿纳米颗粒的固定化生物催化剂或耐溶剂细菌实现更好的硫去除，并从这些杂环中获得有价值的中间体。其他最近的进展已经证明了微生物对氮杂环化合物的角二氧化作用的机制。然而，这些技术还不能大规模应用，因此未来的研究必须调查这些过程的工业应用的适当修改。本文综述了近年来微生物降解硫、氮、氧杂环化合物的研究进展。
Sulfur (S), nitrogen (N) and oxygen (O) heterocycles are among the most potent environmental pollutants. Microbial degradation of these pollutants is attracting more and more attention because such bioprocesses are environmentally friendly. The biotechnological potential of these processes is being investigated, for example, to achieve better sulfur removal by immobilized biocatalysts with magnetite nanoparticles or by solvent-tolerant bacteria, and to obtain valuable intermediates from these heterocycles. Other recent advances have demonstrated the mechanisms of angular dioxygenation of nitrogen heterocycles by microbes. However, these technologies are not yet available for large-scale applications so future research must investigate proper modifications for industrial applications of these processes. This review focuses on recent progress in understanding how microbes degrade S, N and O heterocycles.
