Abstract

Three actinomycete strains, MC5-1, MC7-1 and R1-1, were isolated from soil samples collected in Thailand. Their taxonomic positions were determined using a polyphasic approach. The chemotaxonomic characteristics of these strains coincided with those of the genus , i.e. -diaminopimelic acid and glycolyl muramic acid were present in the cell-wall peptidoglycan, the whole-cell sugars were of pattern D, the phospholipids were of type II and the cellular fatty acids were of type 3b. Phylogenetic analysis of the 16S rRNA gene sequences revealed a close relationship between strains MC5-1, MC7-1 and R1-1 (99.8 % sequence similarity) and JCM 12357 (99.3 %). The three novel strains were clearly distinguishable from JCM 12357 from the low DNA–DNA relatedness (≤43.4 %). On the basis of the data presented, strain MC5-1 represents a novel species of the genus , for which the name is proposed. The type strain is MC5-1 (=KCTC 19332=JCM 12873=PCU 267=TISTR 1564).
