Gram-positive rods, 3.0-5.0 x 0.9-1.2 µm. Motile. Produce ellipsoidal endospores that
lie terminally and swell the sporangia.
lie terminally and swell the sporangia.
Colonies after 24 h incubation at 60 ºC on Nutrient Agar are opaque and white in colour,
circular, with smooth edges and glossy surfaces, and diameters of approximately 0.5
mm. Grows at 40-65 ºC, with an optimum at 55 ºC. Grows between pH 6 and 9; no
growth at pH 5. Tolerates up to 2% NaCl. Facultatively anaerobic.

emendation of Geobacillus, G. stearothermophilus, G. jurassicus, G. toebii, G. thermodenitrificans and G. thermoglucosidans
(nom. corrig., formerly 'thermoglucosidasius'); transfer of Bacillus thermantarcticus to the genus as G. thermantarcticus comb. nov.;
proposal of Caldibacillus debilis gen. nov., comb. nov.; transfer of G. tepidamans to Anoxybacillus as A. tepidamans comb. nov.; and
proposal of Anoxybacillus caldiproteolyticus sp. nov. Int J Syst Evol Microbiol 2012; 62:1470-1485.
Positive results for aesculin hydrolysis, catalase, ONPG, starch hydrolysis, acid production from: N-acetylglucosamine, amygdalin, L-
arabinose, arbutin, cellobiose, D-fructose, galactose, gentiobiose, D-glucose, glycerol, myo-inositol, lactose, maltose, D-mannose,
melezitose, melibiose, methyl D-glucoside, raffinose, ribose (weak), salicin, starch, sucrose, trehalose, turanose and D-xylose.
Negative results for arginine dihydrolase, caseinase, citrate utilization, gelatin hydrolysis, H2S production, indole production, lysine
decarboxylaseoxidase, ornithine decarboxylase, tryptophan deaminase, urease, acid production from: adonitol, D-arabinose, D- and
L-arabitol, dulcitol, erythritol, D- and L-fucose, gluconate, glycogen, inulin, 2- and 5-ketogluconate, D-lyxose, mannitol, methyl D-
mannoside, methyl xyloside, rhamnose, sorbitol, L-sorbose, D-tagatose, xylitol and L-xylose.
Contradictory results for nitrate reduction and Voges–Proskauer test.
