| Abstract: | Verrucosispora isolate AB-18-032T, the abyssomicin- and proximicin-producing actinomycete, has chemotaxonomic and morphological properties consistent with its classification in the genus Verrucosispora. The organism formed a distinct phyletic line in the Verrucosispora 16S rRNA gene tree sharing similarities of 99.7%, 98.7% and 98.9% with Verrucosispora gifhornensis DSM 44337T, Verrucosispora lutea YIM 013T and Verrucosispora sediminis MS 426T, respectively. It was readily distinguished from the two latter species using a range of phenotypic features and from V. gifhornensis DSM 44337T, its nearest phylogenetic neighbor, by a DNA G+C content of 65.5 mol% obtained by thermal denaturation and fluorometry and DNA:DNA relatedness values of 64.0% and 65.0% using renaturation and fluorometric methods, respectively. It is apparent from the combined genotypic and phenotypic data that strain AB-18-032T should be classified in the genus Verrucosispora as a new species. The name Verrucosispora maris sp. nov. is proposed for this taxon with isolate AB-18-032T (= DSM 45365T = NRRL B-24793T) as the type strain. |
