Abstract

The taxonomic positions of two environmental isolates from South Korea were established using a combination of genotypic and phenotypic data. The organisms, designated PB314 and Ho-08, were Gram-negative, rod-shaped and non-spore-forming and had chemotaxonomic properties consistent with their classification in the genus 16S rRNA gene tree, the highest sequence similarities being shown to the type strains of (96.3–96.7 %) and (96.3–96.4 %). The isolates shared relatively high 16S rRNA gene sequence similarity (98.1 %) but had a DNA–DNA relatedness value of only 22 %. Chemotaxonomic data revealed that both strains possess quinone system MK-8 as the predominant compound, C 7 and C as major fatty acids and ornithine as a diamino acid in the peptidoglycan structure, corroborating our assignment of the strains to the genus . The results of phylogenetic analyses based on 16S rRNA gene sequences, DNA–DNA relatedness values and physiological and biochemical tests clearly demonstrated that the two strains represent distinct species. On the basis of these data, two novel species, sp. nov. (type strain PB314 =KCTC 12552 =NBRC 101311) and sp. nov. (type strain Ho-08 =KCTC 12553 =NBRC 101312), are proposed.
