摘要: 从广东云浮硫铁矿坑水中分离得到了氧化亚铁硫杆菌(Acidithiobacillus ferrooxidans)Y1菌株,并对其生长规律进行了初步的研究。发现随着时间的变化,培养基溶液中的Fe^2+浓度与细菌数量呈明显的负相关,间接证明了A.f菌通过钒化Fe^2+来获得能量。当溶液中Fe^3+浓度达到一定程度的时候形成黄钾铁矾沉淀,而溶液的pH值会先变大后变小,维持在2.0~2.5之间。

Abstract: A strain of Acidithiobacillus ferrooxidans Y1 was isolated front acid mine drainage in Yunfu sulfide mine in Guangdong Procince.antd its growth rule was prelinminarily studied.The results show that negative correlation exists between the cell numbers and the ferrous concentration in culture medium along with time.which indirectly proves that Acidithiobacilluts ferrooxidans obtained energy through oxidating ferrous.When ferric iron concentration was high enough in the solution,jarosite was produced.In this process,the pH value of the solution became larger firstly and then smaller, always maintains in the range of 2.0~2.5.
