Ecology
Source
isolated from a sample of sediment collected under a cyanobacterial mat developing in a freshwater hot spring in the Alla River (Barguzin Valley, Buryatiya, Russia).
Morphology
Cells are non-endospore-forming, motile, straight to slightly curved rods (0.5-0.6 × 3.0-7.0 µm). Cells occur singly or in short chains and exhibit tumbling motility due to peritrichous flagellation. In agar-shake cultures, brown spherical colonies (1.0-1.5 mm in diameter) appear after incubation at 50 °C for 18-24 h.
