Actinoalloteichus hymeniacidonis sp. nov., an actinomycete isolated from the marine sponge Hymeniacidon perleve

A polyphasic study was undertaken to establish the taxonomic status of a Gram-positive, aerobic actinomycete, strain HPA177 T , isolated from a marine sponge, Hymeniacidon perleve . The organism formed branching, non-fragmenting vegetative hyphae and produced black pigment. Chemotaxonomic characteristics were consistent with its assignment to the genus Actinoalloteichus . Analysis of the 16S rRNA gene sequence showed that strain HPA177 T formed a robust clade with type strains of the genus Actinoalloteichus , but was distinct from them. A number of phenotypic characteristics also readily distinguished strain HPA177 T from species of the genus Actinoalloteichus with validly published names. On the basis of the above data, it is proposed that strain HPA177 T represents a novel species, Actinoalloteichus hymeniacidonis sp. nov. The type strain of Actinoalloteichus hymeniacidonis is HPA177 T (=CGMCC 4.2500 T =JCM 13436 T ).
