Abstract:
Nine Aeromonas strains having a brown exopigment were isolated during the microbiological examination of river water. These brown-pigmented aeromonads were characterized by the phenotyping, fatty-acid methyl-ester analysis and ribotyping. All methods identically confirmed that the group of brown-pigmented aeromonads is quite heterogeneous. Apart from the Aeromonas media taxon, the brown-pigmented aeromonads in river water were represented also by strains of A. allosaccharophila and A. salmonicida subsp. pectinolytica.
