Goris, Forsyth, Rodriguez-Diaz, Heyndrickx and De Vos 2004.
Gram-variable, motile rods, 0.7-0.9 x 2.5-4.5 µm, occurring singly; Gram-positive
reactions are only in cultures of less than 18 h at 30 ºC. Produce paracentral or
subterminal, ellipsoidal endospores wich usually swell the sporangia.
Colonies are 2–5 mm in diameter, have a granular appearance and butyrous texture,
with opaque, cream-colored center and translucent irregular margins after 2 days on
TSA. Aerobic. Growth temperature 20-55 ºC (optimum 40 ºC); pH 5-9 (optimum pH 7).
NaCl, alantoin or urate are not required for growth.
Isolated from unheated volcanic soil taken from the eastern lava flow of Candlemas Island, South Sandwich archipelago.
Sensitive to ampicillin, chloramphenicol, colistin sulphate, kanamycin, nalidixic acid, nitrofurantoin, streptomycin  and tetracycline.
Undetermined.
