采自某高砷金矿的氧化亚铁硫杆菌（ＳＨ－Ｔ）菌种是优良的菌种。通过一系列的极端条件试验表明它具有高的生存温度：２５～５２℃，在４３℃时还具有氧化二价铁的能力，耐热耐砷性强，可以作为处理难浸金矿的浸矿菌种．
Thiobacillus ferrooxidans (SH-T) strains collected from a high-arsenic gold mine are excellent strains. Through a series of extreme conditions tests showed that it has a high survival temperature: 25 ~ 52 ℃, at 43 ℃ also has the ability to oxidize ferrous iron, heat and arsenic-resistant, can be used as refractory gold ore leaching Species.
