The Genera Caulococcus and Kusnezovia

Perfil’ev and Gabe (1965) observed bacteria of the genera Caulococcus and Kusnezovia, along with Metallogenium and Siderococcus, as manganese-and, to a lesser extent, iron-depositing or -oxidizing organisms of mud and sandy deposits. The use of capillary devices that permit microscopic observation (peloscopes) has permitted some observations of structure and colonial morphologies. Their morphologies suggest that these organisms might be related to Acholeplasma, Metallogenium, or Siderococcus, but lack of axenic cultures has prevented thorough study of their physiology and composition; an understanding of the nature of these rather rare bacteria is still not complete.
