Genetic analyses of 16S rRNA sequences of K. denitrificans. A. Rooted phylogenetic tree based on 16S rRNA sequence comparisons. Bar indicates 0.01% differences in
nucleotide sequences. Horizontal distances are equivalent to genetic distances. Type strains are indicated by adding T at the last of each name. 16S rRNA sequences are available for
electronic retrieval from GenBank under the accession numbers indicated in each parenthesis. B. Variations of DNA sequences of the 16S rRNA gene of K. denitrificans. Numbers are
corresponding to positions in the Escherichia coli 16S rRNA numbering system. Bases deviated from the sequencing result of type-strain ATCC33394 were underlined.
