Abstract

A novel marine actinomycete, designated strain CMAA 1452(T), was isolated from the sponge Scopalina ruetzleri collected from Saint Peter and Saint Paul Archipelago, in Brazil, and subjected to a polyphasic taxonomic investigation. The organism formed a distinct phyletic line in the Saccharopolyspora 16S rRNA gene tree and had chemotaxonomic and morphological properties consistent with its classification in this genus. It was found to be closely related to Saccharopolyspora dendranthemae KLBMP 1305(T) (99.5% 16S rRNA gene sequence similarity) and shared similarities of 99.3, 99.2 and 99.0% with 'Saccharopolyspora endophytica' YIM 61095, Saccharopolyspora tripterygii YIM 65359(T) and 'Saccharopolyspora pathumthaniensis' S582, respectively. DNA-DNA relatedness values between the isolate and its closest phylogenetic neighbours, namely S. dendranthemae KLBMP 1305(T), 'S. endophytica' YIM 61095 and S. tripterygii YIM 65359(T), were 53.5, 25.8 and 53.2 %, respectively. Strain CMAA 1452(T) was also distinguished from the type strains of these species using a range of phenotypic features. On the basis of these results, it is proposed that strain CMAA 1452(T) (= DSM 103218(T) = NRRL B-65384(T)) merits recognition as the type strain of a novel Saccharopolyspora species, Saccharopolyspora spongiae sp. nov.
