sp. nov. and sp. nov., two radiation-resistant bacteria from soil No Access

Abstract

Two bacterial strains, designated BT189 and BT664, were isolated from soil sampled in the Republic of Korea. Phylogenetic analysis based on the 16S rRNA gene sequences showed that strains BT189 and BT664 belonged to the genus , family (order ). The 16S rRNA genes of the two strains shared a sequence similarity of 93.7 %. The closely related species of strain BT189 were DG7B (97.1 % 16S rRNA similarity) and DG7A (96.7 %). The closest related species to strain BT664 were DG5B (95.3 %) and MIMtkLc17 (95.2 %). The genome sizes of strains BT189 and BT664 were 5 285 287 and 5 475 357 bp, respectively. The genomic DNA G+C contents of strains BT189 and BT664 were 63.2 and 59.3 mol%, respectively. The main fatty acids of strain BT189 were iso-C, anteiso-C and summed feature 3 (C 6/C 7), and those of strain BT664 were iso-C, C 5 and summed feature 3 (C 6/C  7). The main polar lipid in both strains was phosphatidylethanolamine and the predominant respiratory quinone was MK-7, supporting the affiliation of these strains with the genus . Based on the results of biochemical, chemotaxonomic and phylogenetic analyses, two novel species, BT189 (=KCTC 72341=NBRC 114843) and BT664 (KACC 21967=NBRC 114856), are proposed.
