Gram-negative rods, 2.5–3.2 x 0.9–1.2 µm, singly or grouped in pairs. Nonmotile.
Colonies on agar plates and agar deeps are 0.3 to 0.5 mm in diameter, lens shaped,
and white. Growth occurs under aerobic and anaerobic conditions. Transforms
phenylalanine and other phenyl precursors into toluene. Toluene is produced from
phenylalanine, phenylacetate, phenyllactate, and phenylpyruvate only in the presence
of an additional carbon source. Phenol is produced when phenylalanine is replaced
by tyrosine. Optimum temperature for anaerobic growth is 22 ºC.
