本文对一类海洋放线菌进行了分类学研究，阐明了它们的分类，这些放线菌以前被命名为mar1，并被认为属于小单孢科。这些生物具有与其归属于该分类单元一致的表型特性。这些菌株在16S rRNA小单孢子科基因树中形成了一个独特的分类单元，并具有一系列表型特性，使它们与该家族中所有有效发表名称的属成员区分开来。该属包含两个物种，使用一系列基因型和表型标准识别，包括比较16S-23S rRNA基因间隔区和DNA-DNA相关性数据。这些新分类群的命名为模式种Salinispora arenicola sp. nov.和模式菌株Salinispora tropica sp. nov.，这些新分类群的模式菌株分别为菌株CNH-643(T) (= ATCC BAA-917（T) = DSM 44819(T)）和菌株CNB-440(T) (= ATCC BAA-916（T) = DSM 44818(T)）。
A taxonomic study was carried out to clarify the taxonomy of representatives of a group of marine actinomycetes previously designated MAR 1 and considered to belong to the family Micromonosporaceae. The organisms had phenotypic properties consistent with their assignment to this taxon. The strains formed a distinct taxon in the 16S rRNA Micromonosporaceae gene tree and shared a range of phenotypic properties that distinguished them from members of all of the genera with validly published names classified in this family. The name proposed for this novel taxon is Salinispora gen. nov. The genus contains two species recognized using a range of genotypic and phenotypic criteria, including comparative 16S-23S rRNA gene spacer region and DNA-DNA relatedness data. The names proposed for these taxa are Salinispora arenicola sp. nov., the type species, and Salinispora tropica sp. nov., the type strains of these novel species have been deposited in service culture collections as strain CNH-643(T) ( = ATCC BAA-917(T) = DSM 44819(T)) and strain CNB-440(T) ( = ATCC BAA-916(T) = DSM 44818(T)), respectively.
