【摘要】 以高含量的硫化物金精矿为驯化介质 ,将驯化后的氧化亚铁硫杆菌 (T.f菌 )用紫外线、微波作为诱变剂进行选育 ,经过诱变选育的 T.f菌的氧化活性由未被驯化、诱变前的 0 .0 7g/L· h提高到 3.18g/L·h;氧化活性提高了 4 0多倍 ,有效地提高了氧化亚铁硫杆菌对硫化物的氧化分解能力 ,为优势浸矿菌种的选育提供了简便、有效的育种手段更多还原

【Abstract】 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.更多还原
