Abstract
Knowledge of the diversity of magnetotactic bacteria in natural environments is crucial for understanding their contribution to various biological and geological processes. Here we report a high diversity of magnetotactic bacteria in a freshwater site. Ten out of 18 operational taxonomic units (OTUs) were affiliated with the Deltaproteobacteria. Some rod-shaped bacteria simultaneously synthesized greigite and magnetite magnetosomes.
摘要
了解自然环境中磁细菌的多样性对于理解它们对各种生物和地质过程的贡献至关重要。在这里，我们报告了一个淡水地点中磁细菌的高度多样性。18 个操作分类单元（OTUs）中有 10 个与δ变形菌门有关。一些杆状细菌同时合成了陨铁硫矿和磁铁矿磁小体。
