A mixed bacterial culture consisting of eleven different strains was investigated in view of its ability to degrade 6‐aminonaphthalene‐2‐sulphonic acid (6A2NS). Taxonomic characterization of the microorganisms showed that they belonged to three genera: Flavobacterium, Bacillus and Pseudomonas . None of the single strains could degrade 6A2NS. Some of 4–5‐member co‐cultures degraded it, but lost the ability in future subcultures. Only the mixed culture consisting of all eleven strains were stable and efficacious in degradation through numerous subcultures. The well‐adapted mixed culture degraded the compound fast and without accumulation of intermediates, with a low increase in cell biomass and a high degree of mineralization.
