Species description is based on a single isolate.
Gram-positive rods, 0.4-0.6 x 2.0-5.0 µm. Motile by peritrichous flagella. Produce
central ellipsoidal or cylindrical endospores in swollen sporangia.
Growth occurs at 45-70 ºC (optimum, 45 ºC), pH 6.0-10.0 (optimum, pH 7.0) and with
0-13% (w/v) NaCl (optimum, 3%). Growth does not occurr under anaerobic conditions
on Marine Agar.
Isolated from the hydrothermal sediments in Manus Basin in the western Pacific Ocean.
