Fe-oxidizing microbial matsFe-oxidizing microbial mats. A. Atypical freshwater iron mat in a slow-moving stream where Fe(II)-enriched groundwater is mixing with oxygenated surface water, resulting in growth of Fe-oxidizing bacteria and precipitation of iron oxides; B & C. phase contrast and epiflouresence images of the common sheath-forming Fe-oxidizer Leptothrix ochracea (bar = 5 µm); D, the stalk-forming Fe-oxidizer Gallionella ferruginea, note the bean-shaped cells in the process of cell division at the end of the Fe-oxide encrusted stalk (bar = 5 µm); E, an iron mat associated with a deep-sea hydrothermal vent (1000 mbsl) at Loihi Seamount; F, TEM image of biogenic oxides produced at Loihi, note the variety of helical stalks and tubular sheath-like filaments (bar = 10 µm); G, phase contrast image of unidentified Zetaproteobacteria that are marine Fe-oxidizers growing at the ends of iron-oxide filaments (cells denoted by arrows) from an in-situ incubation at Loihi (bar = 5 µm).

Thioploca is a filamentous sulfur-oxidizing bacterium, with the unusual characteristic of building sheaths around bundles of its filaments. They can travel up and down the sheaths by gliding motility. Thioploca can be found in sediments and also in microbial mats. These specimens are from Okinawa, Japan.
