A Delftia tsuruhatensis strain capable of consuming aniline as the sole source of carbon, nitrogen, and energy at concentrations of up to 3200 mg/l was isolated from activated sludge of the sewage disposal plants of OAO Volzhskii Orgsintez. The strain grew on catechol and p-hydroxybenzoic acid but did not consume phenol, 2-aminophenol, 3-chloroaniline, 4-chloroaniline, 2,3-dichloroaniline, 2,4-dichloroaniline, 3,4-dichloroaniline, 2-nitroaniline, 2-chlorophenol, or aminobenzoate. Aniline is degraded by cleavage of the catechol aromatic ring at the ortho position. Cells were immobilized on polycaproamide fiber. It was shown that the strain degraded aniline at 1000 mg/l in a continuous process over a long period of time.
