Abstract

A coccoid, non-motile actinobacterium, designated strain YIM 70003, was isolated from a saline, alkaline, desert-soil sample from Egypt. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the organism formed a distinct phyletic line within the genus and was most closely related to DSM 14382 (98·6 % sequence similarity) and DSM 20447 (98·2 %). Chemotaxonomic data, including the Lys–Ala peptidoglycan type, the presence of phosphatidylglycerol and diphosphatidylglycerol as the predominant phospholipids, the presence of MK-8(H) and MK-9(H) as the major menaquinones, the predominance of fatty acids ai-C and i-C and the DNA G+C content, also supported the affiliation of the isolate to the genus . The low DNA–DNA relatedness with DSM 14382 (56·6 %) and DSM 20447 (15·5 %) in combination with phenotypic data show that strain YIM 70003 should be classified as a novel species of the genus . The name sp. nov. is proposed, with strain YIM 70003 (=CCTCC AA203006=CIP 107966=KCTC 19010=DSM 17006) as the type strain.
