Abstract
A novel actinomycete, designated strain RS11V-5T, was isolated from rhizosphere soil of Oryza sativa L. collected from Roi Et Province, Thailand, and its taxonomic position was evaluated. Cells of strain RS11V-5T were Gram-stain-positive, aerobic, and non-motile. Whole-cell hydrolysates contained meso-diaminopimelic acid, arabinose, galactose, glucose and ribose. MK-8(H4) was detected as the predominant menaquinone of this strain. The polar lipids were diphosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine, hydroxy-phosphatidylmethylethanolamine, hydroxy-phosphatidylethanolamine, an unidentified phospholipid, an unidentified aminolipid and an unidentified glycolipid. The major fatty acids were iso-C16 : 0, C16 : 0 and C16 : 1 ω7c/C16 : 1 ω6c. Phylogenetic analyses based on the 16S rRNA gene sequences showed that strain RS11V-5T belonged to the genus
Pseudonocardia
and had high 16S rRNA sequence similarity of 99.3 % to
Pseudonocardia kujensis
KCTC 29062T and less than 98.4 % to other members of the genus
Pseudonocardia
. The DNA G+C content of the strain RS11V-5T was 73.3 mol%. Strain RS11V-5T showed 46.5 % digital DNA–DNA hybridization, 92.2 % orthologous average nucleotide identity (OrthoANI), 90.2 % ANI based on blast and 92.7 % ANI based on MUMmer to
P. kujensis
KCTC 29062T. Based its phenotypic, genotypic, phylogenetic and chemotaxonomic characteristics, strain RS11V-5T represents a novel species of the genus
Pseudonocardia
, for which the name Pseudonocardia terrae sp. nov. is proposed. The type strain is RS11V-5T (=TBRC 15286T=NBRC 115296T).
