摘　　要：湖泊作为内陆水体的重要组成部分,因将大气、岩石和水圈等联系起来而成为物质元素循环的关键作用场所.铁是地壳中含量排名第四的元素,普遍存在于各种矿物相中.硫以多种价态存在于多种无机和有机化合物中.湖泊中铁和硫在不同价态之间的相互转变和相互影响构成了湖泊铁硫循环过程,而微生物在其中发挥着主导作用,是循环中不可或缺的环节.本文总结了参与湖泊铁循环和硫循环的微生物类型、代谢途径及环境影响因子,特别聚焦于青藏高原湖泊铁硫循环相关微生物研究现状,并对未来青藏高原湖泊微生物驱动的铁硫循环研究方向进行了展望.Lake,as an important part of inland water bodies,is a key site of action for the cycling of material elements by linking the atmosphere,rocks and hydrosphere.Iron,the fourth most abundant element in the Earth’s crust,is prevalent in various mineral phases,and sulfur exists in various inorganic/organic compounds in a variety of valence states.The mutual transformation and interaction between iron and sulfur in different valence states in lakes constitute the process of iron and sulfur cycling in lakes,in which microorganisms play a dominant role and become an indispensable part of the cycle.This review summarizes the types of microorganisms,metabolic pathways and environmental influences involved in the iron and sulfur cycles in lakes,focusing on the current status of microbial research related to the iron and sulfur cycles in lakes on the Qinghai-Xizang Plateau,and presenting the future direction of microbial-driven iron and sulfur cycling research in lakes on the Qinghai-Xizang Plateau.
