Comparative 16S rRNA gene sequence analysis showed that the strains belonged to the family Nocardiaceae . Strains A2012T and A2019T were most closely related to Nocardia caishijiensis DSM 44831T (98.9 %) and Nocardia mexicana CIP 108295T (98.6 %), respectively; similarity to other type strains of the genus Nocardia ranged from 96.9 to 97.9 %. However, DNA–DNA relatedness and phenotypic data demonstrated that strains A2012T and A2019T could be clearly distinguished from members of the most closely related Nocardia species. It is evident from the genotypic and phenotypic data that the two isolates represent two novel species of the genus Nocardia . It is proposed, therefore, that strains A2012T and A2019T be classified in the genus Nocardia as representatives of Nocardia goodfellowii sp. nov. (type strain A2012T = DSM 45516T = NRRL B-24833T = KCTC 19986T) and Nocardia thraciensis sp. nov. (type strain A2019T = DSM 45517T = NRRL B-24834T = KCTC 19985T), respectively., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.031559-0
