sp. nov., an actinomycete isolated from compost of (Lam.).

A member of the genus , designated RCPT1-4, was isolated from compost of (Lam.), collected from an agricultural area in Rayong province, Thailand. The spore morphology and the presence of ll-diaminopimelic acid in the peptidoglycan indicate that RCPT1-4 shows the typical properties of members of the genus . On the basis of the results of 16S rRNA gene sequence analysis, the strain should be classified as representing a member of the genus and was most closely related to NBRC 12999 with the highest 16S rRNA gene sequence similarity of 99.2 %, followed by NBRC 14215 (99.0 %). In addition, RCPT1-4 shared the highest average nucleotide identity by blast (ANIb) (86.0 %), and digital DNA-DNA hybridization (dDDH) (32.1 %) values with NBRC 14215. Furthermore, several physiological and biochemical differences were observed between RCPT1-4 and the closely related type strains of species with validly published names. These taxonomic data indicated that RCPT1-4 could be considered to represent a novel species of the genus and the name sp. nov. is proposed for this strain. The type strain is RCPT1-4 (=TBRC 11260=NBRC 114303).
