Thanks to the work of Terrance J. Beveridge and other pioneers in the field of metal-microbe interactions, prokaryotes are well known to sequester metals and other ions intracellularly in various forms. These forms range from poorly ordered deposits of metals to well-ordered mineral crystals. Studies on well-ordered crystalline structures have generally focused on intracellular organelles produced by magnetotactic bacteria that are ubiquitous in terrestrial and marine environments that precipitate Fe(3)O(4) or Fe(3)S(4), Fe-bearing minerals that have magnetic properties and are enclosed in intracellular membranes. In contrast, studies on less-well ordered minerals have focused on Fe-, As-, Mn-, Au-, Se- and Cd-precipitates that occur intracellularly. The biological and environmental function of these particles remains a matter of debate.

原核生物中的细胞内矿物质和金属沉积物。

得益于Terrance J. Beveridge和金属-微生物相互作用领域的其他先驱者的努力，原核生物众所周知以各种形式在细胞内螯合金属和其他离子。这些形式从金属的有序沉积到有序的矿物晶体不等。对有序晶体结构的研究通常集中于趋磁细菌产生的细胞内细胞器，这些趋磁细菌在陆地和海洋环境中普遍存在，会沉淀出Fe（3）O（4）或Fe（3）S（4），具有磁性，被封闭在细胞内膜中。相比之下，对序号较差的矿物的研究则集中在细胞内发生的Fe，As，Mn，Au，Se和Cd沉淀物上。这些颗粒的生物学和环境功能仍然是一个有争议的问题。
