A strain of Thiobacillus ferrooxidans was domesticated with high sulphide gold concentrate as a medium and then mutagenized with ultraviolet and microwave.After mutagenic selection,its oxidizing activity increases from 0.07g/L·h to 3.18g/L·h,in other words,its oxidizing activity was raised more than 40 times.It proved that strain′s capability of oxidizing sulphide was improved efficiently.This paper offered a kind of simply but efficient means for the selection of superior leaching strains.
