A Gram-positive bacterium, strain GW8-1761T, was isolated from soil close to the Marmore waterfalls, Terni, Italy. 16S rRNA gene sequence similarity studies showed that strain GW8-1761T belonged to the genus Actinoplanes, being most closely related to Actinoplanes italicus JCM 3165T (98.9 %), A. rectilineatus IFO 13941T (98.5 %), A. palleronii JCM 7626T (97.8 %), A. utahensis IFO 13244T (97.6 %) and A. cyaneus DSM 46137T (97.6 %). Strain GW8-1761T 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(H4); major polar lipids diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol, with phosphatidylcholine and aminoglycolipids absent; major fatty acids C15 : 0, C16 : 0, C16 : 0 iso, C17 : 1
8c and summed feature 3 (C16 : 1
7c and/or C15 : 0 iso 2-OH)] supported the affiliation of strain GW8-1761T to the genus Actinoplanes. The results of DNADNA hybridizations and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain GW8-1761T from the most closely related species. Strain GW8-1761T therefore merits species status, and we propose the name Actinoplanes couchii sp. nov., with the type strain GW8-1761T (=DSM 45050T=CIP 109316T).
A neighbour-joining tree based on 16S rRNA gene sequences showing the position of strain GW8-1761T is available as supplementary material in IJSEM Online.
