Abstract
A member of the genus Streptomyces, designated RCPT1-4T, was isolated from compost of Senna siamea (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 RCPT1-4T shows the typical properties of members of the genus Streptomyces. On the basis of the results of 16S rRNA gene sequence analysis, the strain should be classified as representing a member of the genus Streptomy-ces and was most closely related to Streptomyces fumigatiscleroticus NBRC 12999T with the highest 16S rRNA gene sequence similarity of 99.2%, followed by Streptomyces spiralis NBRC 14215T (99.0%). In addition, RCPT1-4T shared the highest average nucleotide identity by blast (ANIb) (86.0%), and digital DNA–DNA hybridization (dDDH) (32.1%) values with S. spiralis NBRC 14215T. Furthermore, several physiological and biochemical differences were observed between RCPT1-4T and the closely related type strains of species with validly published names. These taxonomic data indicated that RCPT1-4T could be considered to represent a novel species of the genus Streptomyces and the name Streptomyces sennicomposti sp. nov. is proposed for this strain. The type strain is RCPT1-4T (=TBRC 11260T=NBRC 114303T).
