THIOTHRIX EIKELBOOMII
| Class: | Gamma Proteobacteria |
| Genus: | Thiothrix |
| Species: | Thiothrix eikelboomii |
| Description: | Cells are rods and form multicellular filaments. Base- to-tip differentiation in filaments is observed. Cell morphology in filaments is highly variable, and cu-boidal, barrel-shaped, cylindrical, discoid and bead-like cells are often observed. Discoid cells at the base of filaments can range from 1-0 to 3.0 μm in diameter and 0.4 to 0.7 μm in length. Apical cells are 0.6-0.8 μm in diameter and 1-0-5-0 μm in length and form bead-like strings. Knots may be observed in filaments. Gram- negative or Gram-variable. A sheath is absent. Rosettes and a holdfast are formed in some but not all strains. Gliding gonidia are produced from the end of the filaments only in rosette-forming strains. No flagella are present but a tuft of fimbriae is present at the end of the gonidium. Volutin inclusions, sudano- philic granules and poly-β-hydroxybutyrate are observed within cells. |
