趋磁性细菌分布范围很广，在湖泊和池塘底部的沉积物和沿海区域均有分布。
They exist all over the globe, living in lake and pond sediments and in ocean coastal regions.
首次发现趋磁性细菌是上世纪70年代，但一直对磁性小体的作用不是很清楚。
Since the discovery of magnetotactic bacteria in the 1970s, it has not been clear exactly what magnetosomes were for.
本文以氧化亚铁硫杆菌菌株yn - 3为材料，研究在黄铁矿、黄铜矿、磁黄铁矿和闪锌矿等矿物作用下，对YN - 3的生长特性及趋磁性产生的影响。
The growth rate of YN-3 was fastest when sphalerite was the source of energy, the next was pyrrhotite and chalcopyrite, YN-3 had the lowest growth rate under the effect of pyrite.
