The strain, isolate MT1.1T, formed a distinct clade in the Micrococcineae 16S rRNA gene tree together with Dermacoccus nishinomiyaensis DSM 20448T. The organism had chemical and phenotypic properties consistent with its classification in the genus Dermacoccus and could be distinguished from D. nishinomiyaensis DSM 20448T using DNA–DNA relatedness and phenotypic data. The G+C content of the DNA of isolate MT1.1T 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 MT1.1T (=DSM 17573T=NCIMB 14084T). The organism grows well at 40 MPa and hence is piezotolerant., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.64133-0
