Abstract

A novel actinobacterium, designated isolate B138, was isolated from the marine sponge, , which was collected from Praia Guaecá (São 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 and it formed a distinct phyletic line in the 16S rRNA gene tree. It was most closely related to DSM 45037 and DSM 44902 (99.0 % 16S rRNA gene sequence similarity) and DSM 44693 (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 (=CBMAI 1094=DSM 46676) should be classified as the type strain of a novel species of the genus , for which the name sp. nov. is proposed.
