Acidithiobacillus thiooxidans (A. thiooxidans) is a widespread, mesophilic, obligately aerobic, extremely acidophilic, rod-shaped, and chemolithoautotrophic gram-negative gammaproteobacterium. It can obtain energy and electrons from the oxidation of reducible sulfur, and it can fix carbon dioxide and assimilate nitrate, nitrite, and ammonium to satisfy carbon and nitrogen requirement. This bacterium exists as different genomovars and its genome size range from 3.02 to 3.97 Mb. Here, we highlight the recent advances in the understanding of the general biological features of A. thiooxidans, as well as the genetic diversity and the sulfur oxidation pathway system. Additionally, the potential applications of A. thiooxidans were summarized including the recycling of metals from metal-bearing ores, electric wastes, and sludge, the improvement of alkali-salinity soils, and the removal of sulfur from sulfur-containing solids and gases.
氧化亚铁硫杆菌（A. thiooxidans）是一种广泛分布、嗜温、需氧、嗜酸、杆状、化能自养革兰氏阴性γ变形菌。它可以从可还原硫的氧化中获得能量和电子，并且可以固定二氧化碳并同化硝酸盐、亚硝酸盐和铵盐来满足碳和氮的需求。该细菌存在不同的基因组变种，其基因组大小范围为 3.02 至 3.97 Mb。在这里，我们重点介绍了对 A. thiooxidans 一般生物学特征、遗传多样性和硫氧化途径系统的理解的最新进展。此外，还总结了 A. thiooxidans 的潜在应用，包括从含金属矿石、电子废物和污泥中回收金属、改良盐碱土壤以及从含硫固体和气体中去除硫。
