The taxonomic status of an actinobacterial strain isolated from Mariana Trench sediment was determined using a polyphasic taxonomic approach. The strain, isolate MT1.1(T), formed a distinct clade in the Micrococcineae 16S rRNA gene tree together with Dermacoccus nishinomiyaensis DSM 20448(T). The organism had chemical and phenotypic properties consistent with its classification in the genus Dermacoccus and could be distinguished from D. nishinomiyaensis DSM 20448(T) using DNA-DNA relatedness and phenotypic data. The G + C content of the DNA of isolate MT1.1(T) was 65.2 mol%. It is evident that the organism merits recognition as a novel species in the genus Dermacoccus. The name proposed for this taxon is Dermacoccus abyssi sp. nov.; the type strain is MT1.1(T) (=DSM 17573(T) = NCIMB 14084(T)). The organism grows well at 40 MPa and hence is piezotolerant.
采用多相分类方法确定了从马里亚纳海沟沉积物中分离出的一株放线菌的分类地位。该菌株，即分离株MT1.1(T)，在微球菌科16S rRNA基因树中与西之宫皮肤球菌DSM 20448(T)形成一个独特的分支。该菌株具有与皮肤球菌属分类一致的化学和表型特征，并且可以通过DNA-DNA相关性和表型数据与西之宫皮肤球菌DSM 20448(T)区分开来。分离株MT1.1(T)的DNA的G + C含量为65.2 mol%。显然，该菌株应被认定为皮肤球菌属中的一个新物种。为这个分类单元提议的名称是深海皮肤球菌（Dermacoccus abyssi）新种；模式菌株是MT1.1(T)（=DSM 17573(T)=NCIMB 14084(T)）。该菌株在40 MPa压力下生长良好，因此是耐压的。
