Razzell, W. E. (British Columbia Research Council, Vancouver, Canada) and P. C. Trussell. Isolation and properties of an iron-oxidizing Thiobacillus. J. Bacteriol. 85:595-603. 1963. - An organism isolated from acidic copper-leaching waters has been shown to oxidize ferrous ions, sulfur, and metallic sulfides but exhibit peculiar responses to thiosulfate. The name Thiobacillus ferrooxidans has been used to describe it. A pH of 2.5 is optimal for growth on iron, sulfur, and metallic sulfides, but cells free from iron can be obtained from growth at pH 1.6, and sulfur cultures adjusted to pH 5.5 readily attain a pH of 1.8. A stationary cultivation procedure appears superior to percolation techniques for studying the oxidation of finely divided metallic sulfides. Concentrations of soluble copper in excess of 1 g per liter were obtained from chalcopyrite in less than 4 weeks. Chalcocite oxidation proceeded in the absence of iron. Sodium chloride inhibits iron oxidation without preventing oxidation of metallic sulfides by the organism.
拉泽尔，W.E.（加拿大温哥华英属哥伦比亚研究委员会）和P.C.特拉塞尔。一种铁氧化硫杆菌的分离与特性。《细菌学杂志》85:595 - 603。1963年。——从酸性铜浸出水中分离出的一种微生物已被证明能氧化亚铁离子、硫和金属硫化物，但对硫代硫酸盐表现出特殊反应。已用“氧化亚铁硫杆菌”这一名称来描述它。pH值为2.5时最适合在铁、硫和金属硫化物上生长，但在pH值为1.6时生长可获得不含铁的细胞，而将硫培养物调至pH值5.5时很容易达到pH值1.8。对于研究细碎金属硫化物的氧化，静止培养程序似乎优于渗滤技术。在不到4周的时间里，从黄铜矿中获得了每升超过1克的可溶性铜浓度。辉铜矿的氧化在没有铁的情况下进行。氯化钠抑制铁的氧化，但不阻止该微生物对金属硫化物的氧化。
