The actinomycete strain RY35-23(T) was isolated from peat swamp forest soil in Thailand. The taxonomic position of this strain was determined using polyphasic approach. Strain RY35-23(T) showed typical morphology and chemical properties similar to the members in the genus Dactylosporangium. On the basis of 16S ribosomal RNA gene analysis, this strain was closely related to Dactylosporangium fulvum JCM 5631(T) (98.94%), D. roseum JCM 3364(T) (98.87%) and D. darangshiense JCM 17441(T) (98.86%). The DNA-DNA relatedness between strain RY35-23(T) and its closely related species was lower than 70%, the cutoff level for assigning strains to the same species. On the basis of these results mentioned, the strain RY35-23(T) could be distinguished from its closely related type strains and represents a novel species of the genus Dactylosporangium, for which the name Dactylosporangium sucinum (type strain RY35-23(T)=JCM 19831(T)=TISTR 2212(T)=PCU 333(T)) is proposed.
