嗜热古菌异化型硫氧化途径的研究进展

Advances in dissimilatory sulfur oxidation pathways in thermophilic archaea

微生物参与的还原性无机硫化合物的氧化过程是硫地球化学循环的重要组成部分,也可应用于生物冶金工业及酸性矿水治理等方面。嗜热古菌是高温环境中存在的一群特殊的微生物,其所参与的异化型硫氧化途径复杂多样,涉及众多氧化还原酶以及硫转运蛋白。本文将结合我们的研究工作,就参与异化型硫氧化代谢过程的嗜热古菌的种类,以及它们所参与的硫氧化过程进行系统的介绍。

Microorganisms-involved oxidation processes of reduced inorganic sulfur compounds (RISCs) are significant components of sulfur geochemical cycle, and could also be applied in biomining industry and acid mine water treatment. Thermophilic archaea are a special group of microorganisms in high temperature environments. They participate in a variety of dissimilatory sulfur oxidation pathways, involving many redox enzymes and sulfur transporter proteins. In this review, the species of thermophilic archaea involved in the metabolic processes of dissimilatory sulfur oxidation, and the sulfur oxidation processes they participate in will be systematically introduced in combination with our research work.
