Abstract

On the basis of numerical analysis of 100 phenotypic features, the strains of two species, and , were differentiated into two separate phenons corresponding with the macrorestriction patterns of their genomic DNA, as well as with the results of ribotyping and PCR amplification of enterobacterial repetitive intergenic consensus sequences. One of the strains, the F-2 strain, was shown to be marginal, exhibiting the lowest genomic and phenotypic similarity to the type strain DSM 20501. Two of the strains studied (strains SK 06 and SK 05) were phenotypically convergent forming a separate phenon. They were phenotypically similar, even though the genomic DNA of one of them was homologous with that of the type strain, whereas that of the other was homologous with the genomic DNA of the type strain. In such cases, fingerprinting methods (particularly macrorestriction analysis and ribotyping) served as important correctives, as they allow phenotypically convergent strains to be distinguished on the basis of their genomic profiles. The results of this paper support the proposal for the new species as well as the new subspecies subsp. .
