The 16S rRNA gene sequence of strain VN05A0561T
determined herein was 1454 nt long and showed 93.9–
96.9% nucleotide sequence similarity with those of the type
strains of all recognized species of the genus Pseudonocardia.
Strain VN05A0561T was most closely related to the type
strains of Pseudonocardia xinjiangensis (96.9% 16S rRNA
gene sequence similarity), Pseudonocardia chloroethenivorans,
Pseudonocardia hydrocarbonoxydans, Pseudonocardia
alaniniphila, Pseudonocardia aurantiaca (all 96.6%) and
Pseudonocardia asaccharolytica (96.4%). Phylogenetic analysis
based on 16S rRNA gene sequences showed that strain
VN05A0561T formed a cluster with the type strains of P.
asaccharolytica and Pseudonocardia acaciae
