氧化亚铁硫杆菌中磁小体形成相关基因mpsA在不同铁源刺激下的差异表达 刘新星,刘文斌,闫 颖,武海艳,邱冠周 (中南大学 资源加工与生物工程学院,湖南 长沙,410083) 摘 要:为研究氧化亚铁硫杆菌(Acidithiobacillus ferrooxidans)在胞内形成的电子致密的磁性颗粒的相关基因,对氧化亚铁硫杆菌标准菌株ATCC23270的全基因组的生物信... of mpsA gene in Acidithiobacillus ferrooxidans ATCC 23270 LIU Xin-xing, LIU Wen-bin, YAN Ying, WU Hai-yan, QIU Guan-zhou (School of Minerals Processing and Bioengineering, Central South University......
of thiobacillus ferrooxidans LI Qian, YANG Yong-bin, JIANG Tao, QIU Guan-zhou (School of Resources Processing and Bioengineering, Central South University, Changsha 410083, China) Abstract: The electrochemical research of asenopyrite in the presence and absence of thiobacillus ferrooxidans in acidic growth media was investigated. The results show that asenopyrite is firstly oxidized to As2S2, which......
REE behavior and effect factors in AMD-type acidic groundwater at sulfide tailings pond, BS nickel mine, W.A. LEI Liang-qi(雷良奇)1, 2, SONG Ci-an (宋慈安)1, XIE Xiang-li(谢湘漓)1, LI Yan-hong(李艳红)1 1. Department of Resources and Environment Engineering, Guilin University of Technology, Guilin 54......
mineral and thiobacillus ferrooxidans were obtained by calculating according to formula of Young’s equation and contact angle measurements. The results show that surface energy of thiobacillus ferrooxidans is much higher than that of pyrite mineral, and the reaction of pyrite mineral with thiobacillus ferrooxidans causes the reduction of the pyrite surface energy. The interfacial interaction......

, arsR) have been discovered in Acidithiobacillus ferrooxidans. Their gene sequences have been identified and three different arsenic-resistance mechanisms have been elucidated. However, the function of the arsH gene in At. ferrooxidans remains unclear. In order to evaluate the function of the arsH gene, we cloned it and expressed it in Escherichia coli. The protein was purified and its relative......

of pentlandite using modified powder microelectrode with Acidithiobacillus ferrooxidans attached or without on the mineral powder surface. Cyclic voltammetry (CV) results show that at a low potential of about... intermediated phase decomposed entirely; at a higher potential of 0.7 V, the evacuated ferrous ion was oxidized to ferric ion. The presence of Acidithiobacillus ferrooxidans made the oxidation peak current......
