Abstract

Strain VN07A0015 was isolated from soil collected on Cat Ba Island, Vietnam. The taxonomic position of strain VN07A0015 was near M24DS4 (98.5 % 16S rRNA gene sequence similarity) and NBRC 100760 (95.6 %), and it clustered within them; however, this cluster was distant from the type strains of other species of the genus . The aerial mycelia of strain VN07A0015 were greyish and formed imperfect spiral spore chains (retinaculiaperti type) with smooth-surfaced spores. The morphological features of strain VN07A0015 were different from those of the type strains of and . The chemotaxonomic characteristics of strain VN07A0015 were typical for all members of the genus , which possessed -type diaminopimelic acid, menaquinone MK-9(H, H) and the major fatty acids iso-C and iso-C. DNA–DNA relatedness between strain VN07A0015 and NBRC 106164 was less than 30 %. In addition, some physiological and biochemical traits differed from those of . Therefore, we propose that strain VN07A0015 be classified in the genus as a representative of sp. nov. (type strain VN07A0015 = VTCC-A-1889 = NBRC 107860).
