无机硫化合物主要被细菌和古生物界的微生物氧化成硫酸盐。这些微生物产生不同类型的酶，如氧化还原酶和水解酶，用于无机硫化合物的代谢。这些多功能生物催化剂在不同领域具有潜在的生物技术应用，包括回收贵重重金属的生物湿法冶金工艺，以及工业废水中硫化物的生物修复。对无机硫化合物氧化的酶途径的适当了解将有助于调整这些微生物的催化性能，使它们不仅对于给定的反应，而且在苛刻的工业过程中都是最佳的。本文综述了无机硫化合物氧化微生物的分布、与硫代谢有关的各种酶系统以及催化不同酶反应的基因(S)的鉴定。
Inorganic sulfur compounds are oxidized mostly to sulfate by microorganisms belonging to the bacteria and archaea domains. These microorganisms produce different types of enzymes, e. g., oxidoreductases and hydrolases for the metabolism of inorganic sulfur compounds. These versatile biocatalysts have potential biotechnological applications in different fields including biohydrometallurgical processes for recovering precious heavy metals and also for bioremediation of sulfides in industrial waste effluents. Appropriate knowledge on the enzymatic pathways of inorganic sulfur compounds oxidation will help to tailor the catalytic properties of these microorganisms so that they are optimal not only for a given reaction but also in the context of harsh industrial processes. This review describes the distribution of inorganic sulfur compound-oxidizing microorganisms, various enzymatic systems associated with sulfur metabolism, and identification of the gene(s) responsible for catalysis of different enzymatic reactions.
