Its morphological and chemotaxonomic properties, e.g., the presence of mycolic acid and MK-8 (H4ω-cycl) in the cells, showed that strain LPG 2T was a member of the genus Nocardia . 16S rRNA gene sequence analysis revealed that this strain was closely related to Nocardia otitidiscaviarum NBRC 14405T (98.7 %). The low average nucleotide identity–blast and digital DNA–DNA hybridization values (<78.6 and <24.0 %, respectively), and several phenotypic differences between strain LPG 2T and its related Nocardia type strains, indicated that the strain merits classification as representing a novel species of the genus Nocardia , for which we propose the name Nocardia acididurans sp. nov. The type strain is LPG 2T (=TBRC 11242T=NBRC 114293T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.005170
