摘要

趋磁细菌沿地磁力线定向和迁移。趋磁性提高了呼吸性微氧细胞的效率,以有效地找到并保持在首选微氧浓度的位置。趋磁性还可以通过高于或低于首选氧浓度水平的周期性漂移,促进进入营养物质和电子受体浓度较高的区域。

Magnetosomes and magneto-aerotaxis.

Magnetotactic bacteria orient and migrate along geomagnetic field lines. Magneto-aerotaxis increases the efficiency of respiring microaerophilic cells to efficiently find and maintain a position at a preferred microaerobic oxygen concentration. Magneto-aerotaxis could also facilitate access to regions of higher nutrient and electron acceptor concentration via periodic excursions above and below the preferred oxygen concentration level.
