在我国全新世环境中，关于东部古季风变化问题，利用黄土、冰缘、珊瑚、石笋、湖泊地貌与沉积、海岸地貌第四纪等研究对象，从中获取沉积学、磁性信息、沉积地球化学、有机地球化学、色素、生物、微生物化石等方面环境替代性指标，进行古季风重建的研究，取得了长足的进展。

The isolated cells are able to orient and migrate to the magnet in artificial magnetic field but could not orient swimming only under the geomagnetic field. Magnetosomes produced by Acidithiobacillus ferrooxidans were range from 40nm to 90 nm according to the results of TEM. Energy dispersive X-ray analysis indicated that extracted magnetic particles consisted of oxygen and iron. The results show that some Acidithiobacillus ferrooxidans cells have weak magnetotaxis and they could be able to be separated by solid-plate magnetophoresis method from others. With the development of this new isolation method, it is possible that we could do deeper research to generate a comprehensive description of the mechanism that how Acidithiobacillus ferrooxidans synthesize the magnetic particles.

实验结果表明，氧化亚铁硫杆菌具有较弱的趋磁性，在人工磁场下会进行趋磁运动，但仅在地磁场作用下不能定向运动，利用固体平板磁泳筛选纯化含有磁性颗粒的氧化亚铁硫杆菌的方法是切实可行的，磁泳分离技术的进一步完善和改进为传统的微生物菌种分离提供了新的途径，为研究纯氧化亚铁硫杆菌菌株胞内磁性颗粒的形成条件及机理提供了前提条件，也为今后从浸矿细菌中分离筛选更多的含有磁性颗粒的菌株打下基础。
