Gram-positive rods, 0.4-0.5 x 5.0-9.0 µm, occuring singly or in pairs. Cell wall is
composed of three dense layers with two thick layers and a middle thinner layer
separated by two less dense spaces. Motile by few laterally inserted flagella. Spores
are oval, subterminal, swelling the cell; spores formation was induced in the
presence of oxygen and vitamins.

Brown, circular colonies, 1-2 mm in diameter, appeared after 3 days incubation at 50
ºC in roll tubes containing basal agar medium. Strictly anaerobic. Grow in sea salt
medium 12-55 g/l, optimally in sea salt medium 30 g/l. Heterotrophic. Yeast extract is
required for growth on sugars. Grow at 20-58 ºC, optimally at 45 ºC. No growth at 60
ºC. Optimum pH 6.6; range 5.8-8.2. Ferments yeast extract, peptone, Bio-trypticase,
and Casamino acids into a mixture of volatile fatty acids.

Isolated from a North Atlantic Ocean deep-sea hydrothermal chimney.
Undetermined. Because of the ability to degrade amino acids and peptides, the possibility of harmful effects cannot be excluded.

acid produced from: arabinose, cellobiose, dulcitol, lactose, mannitol, melibiose, raffinose, rhamnose, sorbitol, starch, sucrose and
xylose.
