Abstract

Two actinomycete strains, designated YIM 56256 and YIM 61331, were isolated from the roots of and , two Chinese medicinal plants, and their taxonomic status was established based on a polyphasic investigation. The organisms were found to have chemical and morphological markers typical of members of the genus . 16S rRNA gene sequence analysis showed that they were closely related to each other and to E71. A battery of physiological characteristics and levels of DNA–DNA relatedness indicated that strains YIM 56256 and YIM 61331 represent two novel species, clearly different from the related known species. On the basis of the data presented, it is evident that each of these strains represents a novel species of the genus , for which the names sp. nov. (type strain YIM 56256 =KCTC 19158 =DSM 44968) and sp. nov. (type strain YIM 61331 =KCTC 19527 =CCTCC AA 208004) are proposed.
