Abstract
A novel actinobacterium, designated isolate B138(T), was isolated from the marine sponge, Amphimedon viridis, which was collected from Praia Guaeca (Sao Paulo, Brazil), and its taxonomic position was established using data from a polyphasic study. The organism showed a combination of chemotaxonomic and morphological characteristics consistent with its classification in the genus Williamsia and it formed a distinct phyletic line in the Williamsia 16S rRNA gene tree. It was most closely related to Williamsia serinedens DSM 45037(T) and Williamsia deligens DSM 44902(T) (99.0% 16S rRNA gene sequence similarity) and Williamsia maris DSM 44693(T) (97.5% 16S rRNA gene sequence similarity), but was distinguished readily from these strains by the low DNA-DNA relatedness values (62.3-64.4 %) and by the discriminatory phenotypic properties. Based on the data obtained, the isolate B138(T) (= CBMAI 1094(T) = DSM 46676(T)) should be classified as the type strain of a novel species of the genus Williamsia, for which the name Williamsia spongiae sp. nov. is proposed.
