Thiothrix is a filamentous bacteria morphotype as well as a genus with seven recognized species. When referring to Thiothrix genus, we are referring to the actual genetic properties. Within the Thiothrix genus, Thiothrix unzii, Thiothrix lacustris, Thiothrix eikelboomii, and four currently unnamed species are recognized.
The Thiothrix family tree is:
Kingdom Bacteria
Phylum Proteobacteria
Class Gammaproteobacteria
Order Thiotrichales
Family Thiotrichaceae
Genus ThiothrixThiothrix filaments may possess the Thiothrix or the type 021N morphotype. The type 021N morphotype is recognized by its diameter of 1.6-2.5 µm, variable cell shape (rectangular, oval, barrel) and indentations of the septa. (Jenkins, 2004).Typically the type 021N filament type is a long filament, which at high abundance often bridges the flocs together,
