|Prokaryote, Eubacteria Sheathed heterotrophs
|Herpetosiphon, Thioploca and Thiothrix nivea which also have sheaths are a lso included in Nonphotosynthetic, Nonfruiting Gliding Bacteria in the non fruiting section. The genus Lyngbya which is one of the cyanobacteria also has a sheath.
|Gram reaction unknown. Cells show bipolar staining when treated with methylene blue
|Cells rod-shaped with rounded ends, 0.6 x 2.3 um, in chains. Usually two chains (filaments) are wound around one another to give a double spiral which is surrounded by a yellowish, slimy capsule, often with heavy deposits of small ferric hydroxide granules
|There is a slow but incessant motion similar to that of the cyanophytes
|. When the deposits are dissolved with dilute HCl, the cell chains fragment and the individual rods appear as a double zigzag band.. Cells chains may aggregate in distinct layers or even in more or less solid skeins. The filaments separate rapidly upon removal from the normal environment
|Have not been obtained in pure culture..
|Presumably, these organisms are chemoorganotrophic
|Presumably, these organisms are aerobic
