Chemotaxonomic data (peptidoglycan type I, ll-diaminopimelic acid; sugar pattern C, glucose, rhamnose and ribose; polar lipids PI, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol mannosides and phosphatidylinositol) were characteristic of the genus Actinopolymorpha. A phylogenetic tree based on 16S rRNA gene sequences showed that strain YIM 48868T formed a distinct phylogenetic lineage within the genus Actinopolymorpha. Strain YIM 48868T could be differentiated from recognized species by means of phenotypic properties and the predominant menaquinones [MK-9(H6), MK-9(H8), MK-10(H6), MK-10(H8)]. The DNA G+C content was 66.6 mol%. The DNA–DNA relatedness values between strain YIM 48868T and the type strains of A. singaporensis and A. rutila were 48.7 % and 53.1 %, respectively. These data, in combination with phenotypic and chemotaxonomic data, demonstrate that strain YIM 48868T represents a novel species in the genus Actinopolymorpha, for which the name Actinopolymorpha alba sp. nov. is proposed. The type strain is YIM 48868T (=CCTCC AA 208030T=DSM 45243T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.010280-0
