Gram-positive straight rods, 1.0 x 2.5-8.8 µm, occuring single or in pairs. Motile by
peritrichous flagella. Produce terminal, oval spores, swelling the sporangium.

Aerobically grown colonies are pinpoint, yellowish translucent, round with an even
edge; anaerobically grown colonies form white, opaque, round colonies with an even
edge and flat surface. Alkalitolerant, moderate thermophile with an optimum growth
temperature at 60 ºC, range 38-67 ºC (no growth at or below 37 ºC and at or above
68 ºC). Grows at pH 5.7-9.9 at 25 ºC (no rowth at or below pH 5.6 and at or above pH
10.0). Tolerates up to 2.5% NaCl. Requires yeast extract (0.1 g/l) and B12 vitamin for
growth on carbohydrates. Facultatively aerobic.

Isolated from an enrichment culture obtained from the Geyser valley, a geothermally heated environment.
Habitat: volcanically heated thermal fields of the Geyser Valley in Kamchatka, Russia.
