| 摘要: | A Micromonospora-like strain, RtIII47(T), was isolated from a mangrove swamp in Sanya, Hainan Province, China. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that the strain had a close association with the genus Verrucosispora and shared the highest sequence similarity with Verrucosispora lutea YIM 013(T) (98.0%). The strain also showed high 16S rRNA gene sequence similarities to Micromonospora olivasterospora DSM 43868(T) (97.9%), Plantactinospora mayteni YIM 61359(T) (97.9%), Salinispora tropica CNB-440(T) (97.8%), Micromonospora peucetia DSM 43363(T) (97.7%), Micromonospora auratinigra TT1-11(T) (97.7%), Verrucosispora sediminis CGMCC 4.3550(T) (97.6 %) and Salinispora arenicola CNH-643(T) (97.5 %). Phylogenetic analysis based on the gyrB gene sequence supported the conclusion that strain RtIII47(T) should be assigned to the genus Verrucosispora. DNA DNA relatedness between strain RtIII47(T) and the most closely related type strain, V. lutea YIM 013(T), was less than 40 %. Chemotaxonomic results confirmed the taxonomic position of the isolate in the genus Verrucosispora, and revealed differences at the species level in polar lipids, whole-cell sugars and DNA G+C content. A combination of physiological and biochemical tests also distinguished this strain from other Verrucosispora species. Based on genotypic and phenotypic observations, strain RtIII47(T) (=CGMCC 4.5826(T) =NBRC 106684(T)) is proposed as the type strain of a novel species, Verrucosispora qiuiae sp. nov. An emended description of the genus Verrucosispora is also provided. |
