1929.
Motile rods, 1.3 µm in diameter, centrally / paracentrally / subterminally / terminally,
ellipsoidal endospores  in unswollen sporangia.
Colonies on 1% uric acid agar become opaque and are usually nonpigmented but
may become yellowish; margins are often ragged and have hair-like outgrowths, or
the colonies may be rhizoid. Colonies are surrounded by zones of clearing and the
reaction becomes strongly alkaline.
Aerobic. Grow at pH 7 - 9 ; no growth at pH 5-6. Grow in 2% and 5% NaCl; no growth
in 7% and10% NaCl. NaCl is not required for growth. Growth temperature 10 - 40 ºC.
Allantoin & urate are required for growth.
Isolated from soil and poultry litter.
Unknown.

Positive results for hydrolysis of urea,  oxidase & catalase.

Negative results for degradation of tyrosine, deamination of phenylalanine, hydrolysis of gelatin, egg yolk reaction, nitrate
reduction,citrate utilization, hydrolysis of casein & hydrolysis of starch.
