摘要：

Effect of ultraviolet exposure on silver tolerance and growth of Thiobacillus ferrooxidans (ore-isolate) were investigated. Ultraviolet exposure of 30 s was found to influence the ferrous oxidation activity. Ultraviolet-induced silver tolerance as high as 0.414 mM Ag was developed with complete (100%) ferrous oxidation within 163 h. Ultraviolet reexposure of the above culture enhanced ferrous oxidation by about 1.5-fold at 0.276 mM Ag concentration.
