Description is based upon a single isolate.
Gram-positive, motile rods. Produce ellipsoidal / spherical, terminal spores in swollen
sporangia.
Colonies are white, flat and circular, and 1.5 mm in diameter after 2 days on alkaline
oxalate medium at 37 ºC. Anaerobic. Growth stimulated by presence of vitamins (in
yeast extract). Alkaliphilic, grow at pH 8.9-10.5.
Grows at temperature 40 ºC (optimum) to 50 ºC (variable), and in 0-7.5% NaCl media.
Alantoin or urate are not required for growth.
Isolated from red mud bauxite-processing waste, using alkaline oxalate enrichment.
Undetermined.

Positive results for hydrolysis of gelatin (weak), oxidase, catalase & hydrolysis of xylan.
Negative results for hydrolysis of casein & hydrolysis of starch.
Not growing in Voges-Proskauer test.
When tested for acid production from sugars, strain didn't grow in: L-arabinose , D-glucose, D-mannitol, D-mannose, methyl
beta-xyloside, glycogen, salicin, starch & D-xylose.
