Abstract

Magnetotactic bacteria from freshwater and marine sediments orient and navigate along geomagnetic field lines. Their magnetotactic response is based on intracellular, single magnetic domains of ferrimagnetic magnetite, which impart a permanent magnetic dipole moment to the cell.

摘要

来自淡水和海洋沉积物中的趋磁细菌沿着地磁场线定向和导航。它们的趋磁反应基于细胞内亚铁磁性磁铁矿的单磁畴，这些磁畴赋予细胞一个永久磁偶极矩。
