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). 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.

Positive results for acid production (anaerobically) from glucose.
Can utilize (aerobically): ribose, glucose, fructose, galactose, mannitol, maltose, trehalose, sucrose, pyruvate, yeast extract, peptone,
tryptone, casamino acids, and pectin. Anaerobic utilization of glucose, fructose, mannitol, maltose, trehalose, sucrose, and yeast
extract.
Negative results for catalase, gelatinase, oxidase and starch hydrolysis.
No utilization of arabinose, mannose, sorbitol and raffinose.
Variable utilization (positive aerobically, negative anaerobically) of: galactose, ribose and pyruvate.
