Abstract EN
Bacillus strains with >99.7% 16S rRNA gene sequence similarity were characterized with DNA:DNA hybridization, cellular fatty acid (CFA) analysis, and testing of 100 phenotypic traits.
When paired with the most closely related type strain, percent DNA:DNA similarities (% S) for six Bacillus strains were all far below the recommended 70% threshold value for species circumscription with Bacillus nealsonii.
An apparent genomic group of four Bacillus strain pairings with 94%–70% S was contradicted by the failure of the strains to cluster in CFA- and phenotype-based dendrograms as well as by their differentiation with 9–13 species level discriminators such as nitrate reduction, temperature range, and acid production from carbohydrates.
The novel Bacillus strains were monophyletic and very closely related based on 16S rRNA gene sequence.
Coherent genomic groups were not however supported by similarly organized phenotypic clusters.
Therefore, the strains were not effectively circumscribed within the taxonomic species definition.
