The principal biochemical processes of the sulphur cycle are described and the types of organisms known to catalyse the reductive and oxidative phases of the cycle outlined. Attention is drawn to the shortcomings in our current knowledge of the scale of turnover of the sulphur cycle and of our understanding of the microorganisms involved in specialized environments. Examples of some special habitats are used to illustrate these points. The role of sulphate-reducing bacteria and sulphur-oxidizing chemolithotrophs in the formation and recycling of sulphide minerals is described.
本文描述了硫循环的主要生化过程，并概述了已知催化该循环还原和氧化阶段的生物类型。文中提请注意我们目前在硫循环周转规模以及对特殊环境中涉及的微生物的理解方面的知识缺陷。文中通过一些特殊栖息地的例子来说明这些要点。还描述了硫酸盐还原菌和硫氧化化能自养菌在硫化物矿物形成和循环中的作用。
