Asselineau and Mandel 1987.
Gram-variable rods and filaments, 1.8 µm diameter, motile. Forms ellipsoidal
endospores which do not swell the sporangia.
Colonies are opaque with matt surface, circular, flat, off-white. Prototrophic, use
aromatic acids and fenols, but not carbohydrates and aminoacids (excepting glycine)
as carbon and energy sources. Grows in media containing yeast extract and
Na-acetate or benzoate. Growth is observed at pH 7; optimum temperature 32 ºC.
NaCl, allantoin or urate are not required for growth. No growth in 5, 7 or 10% NaCl.
Isolated from pasteurized soil by aerobic enrichment in minimal medium containing benzoate, p-hydroxybenzoate or cyclohexane
carboxylate. No growth in the presence of lysozyme.
