A Gram-positive, aerobic, non-motile actinobacterium, designated strain Ms392AT, was isolated from an ocean-sediment sample collected from the South China Sea. The isolate contained chemical markers that supported chemotaxonomic assignment to the genus Amycolatopsis. On the basis of an analysis of 16S rRNA gene sequence similarities, strain Ms392AT represents a novel subclade within the genus Amycolatopsis, with Amycolatopsis palatopharyngis 1BDZT as its closest phylogenetic neighbour (99.4 % similarity). However, DNA–DNA hybridization demonstrated that strain Ms392AT was distinct from A. palatopharyngis AS 4.1729T (48.6 % relatedness). The polyphasic analysis demonstrated that the ocean isolate can be clearly distinguished from recognized species of the genus Amycolatopsis. Therefore, strain Ms392AT represents a novel species of the genus Amycolatopsis, for which the name Amycolatopsis marina sp. nov. is proposed. The type strain is Ms392AT (=CGMCC 4.3568T =NBRC 104263T).

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain Ms392AT is EU329845.
