Gram-positive, large rods, 0.7-1.5 x 3.3-7.0 µm, occurring singly or in chains. Motile.
Produce terminal ellipsoidal or cylindrical endospores in slightly swollen sporangia.
Produce terminal ellipsoidal or cylindrical endospores in slightly swollen sporangia.
Colonies on peptone-yeast extract are whitish, about 5 mm in diameter with irregular
margin. Grows at 35-67 ºC (optimum, 55-60 ºC), at pH 5.0-5.5 to 8.5-9.5 (optimum pH
6.0-8.0) and in 0-3% (w/v) NaCI (optimum 0.5% NaCl). Strictly aerobic (A. rupiensis) or
facultatively anaerobic (A. geothermale)

A. rupiensis was solated from terrestrial hot spring at Rupi basin, Bulgaria. Susceptible to tetracycline, gentamycin, streptomycin,
erythromycin, carbenicillin and chloramphenicol. Resistant to ampicillin, oxacillin, penicillin and nalidixic acid.
A. geothermale was isolated from deposits clogging aboveground filters from the geothermal power platform of Groß Schönebeck in
northern Germany.
