The magnetic properties (first-order reversal curves, ferromagnetic resonance and decomposition of saturation remanent magnetization acquisition) of Magnetovibrio blakemorei, a cultivated marine magnetotactic bacterium, differ from those of other magnetotactic species from sediments deposited in lakes and marine habitats previously studied. This finding suggests that magnetite produced by some magnetotactic bacteria retains magnetic properties in relation to the crystallographic structure of the magnetic phase produced and thus might represent a 'magnetic fingerprint' for a specific magnetotactic bacterium. The use of this fingerprint is a non-destructive, new technology that might allow for the identification and presence of specific species or types of magnetotactic bacteria in certain environments such as sediments.
海洋趋磁细菌 Magnetovibrio blakemorei 的磁性（一级反转曲线、铁磁共振和饱和剩余磁化强度获取的分解）与之前在湖泊和海洋生境沉积物中研究的其他趋磁物种不同。这一发现表明，一些趋磁细菌产生的磁铁矿保留了与磁相产生的晶体结构有关的磁性，因此可能代表特定趋磁细菌的“磁指纹”。这种指纹的使用是一种非破坏性的新技术，可能允许在某些环境（如沉积物）中识别和存在特定的趋磁细菌种类或类型。
