在铁氧化过程中，氧化亚铁硫杆菌能够耐受高浓度的锌、镍、铜、钴、锰和铝(大于10g/L)。银以及碲、砷和硒的阴离子在50-100毫克/升的浓度下是有毒的。钼(以钼酸盐形式)的浓度在5毫克/升以上时，是致命的。氧化亚铁。在硫代硫酸盐氧化过程中，对锌、镍和钴的耐受性大大降低，钴的毒性至少增加了2000倍，锌和镍的抑制水平分别为600 mg锌/升和150 mg镍/升。在硫氧化过程中，对重金属的耐受性扩展到5g/升以上。在铁氧化过程中，适应锌、镍或铜也可以提高对其他一些金属的耐受性。
During iron oxidation,Thiobacillus ferrooxidans (Ferrobacillus ferrooxidans)was able to tolerate high concentrations of Zn, Ni, Cu, Co, Mn and Al (more than 10 g/litre). Silver and anions of tellurium, arsenic and selenium were toxic in concentrations of 50–100 mg/litre. Molybdenum (as molybdate), at concentrations above 5 mg/litre, was lethal toT. ferrooxidans.During thiosulphate oxidation, the tolerance to Zn, Ni and Co was greatly reduced, cobalt now being at least 2000 times more toxic, and the inhibitory levels of Zn and Ni being 600 mg Zn/litre and 150 mg Ni/litre.During sulphur oxidation, the tolerance to heavy metals extended to concentrations above 5 g/litre.Adaptation to Zn, Ni or Cu during iron oxidation was found to result in increased tolerance to some of the other metals also.
