title: Actinoplanes couchii sp. nov.
abstract: A Gram-positive bacterium, strain GW8-1761(T), was isolated from soil close to the Marmore waterfalls, Terni, Italy. 16S rRNA gene sequence similarity studies showed that strain GW8-1761(T) belonged to the genus Actinoplanes, being most closely related to Actinoplanes italicus JCM 3165(T) (98.9 %), A. rectilineatus IFO 13941(T) (98.5 %), A. palleronii JCM 7626(T) (97.8 %), A. utahensis IFO 13244(T) (97.6 %) and A. cyaneus DSM 46137(T) (97.6 %). Strain GW8-1761(T) could be distinguished from any other Actinoplanes species with validly published names by 16S rRNA gene sequence similarity values of less than 97.5 %. Chemotaxonomic data [major menaquinone MK-9(H(4)); major polar lipids diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol, with phosphatidylcholine and aminoglycolipids absent; major fatty acids C(15 : 0), C(16 : 0), C(16 : 0) iso, C(17 : 1)omega8c and summed feature 3 (C(16 : 1)omega7c and/or C(15 : 0) iso 2-OH)] supported the affiliation of strain GW8-1761(T) to the genus Actinoplanes. The results of DNA-DNA hybridizations and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain GW8-1761(T) from the most closely related species. Strain GW8-1761(T) therefore merits species status, and we propose the name Actinoplanes couchii sp. nov., with the type strain GW8-1761(T) (=DSM 45050(T)=CIP 109316(T)).
