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)).
开展了一项多相研究，以确定从海洋海绵珍珠拟海鞘（Hymeniacidon perleve）中分离出的革兰氏阳性需氧放线菌菌株HPA177(T)的分类地位。该菌形成分支且不碎裂的营养菌丝，并产生黑色色素。化学分类特征表明它属于放线异壁放线菌属（Actinoalloteichus）。16S rRNA基因序列分析表明，菌株HPA177(T)与放线异壁放线菌属模式菌株形成一个稳定的分支，但又与其不同。一些表型特征也能轻易地将菌株HPA177(T)与已有效发表名称的放线异壁放线菌属的种区分开来。基于上述数据，建议将菌株HPA177(T)代表一个新物种，即珍珠拟海鞘放线异壁放线菌（Actinoalloteichus hymeniacidonis sp. nov.）。珍珠拟海鞘放线异壁放线菌的模式菌株为HPA177(T)（=CGMCC 4.2500(T)=JCM 13436(T)）。
