abstract= A novel mesophilic marine actinobacterial strain, designated as SCSIO 08198T, was isolated from a deep-sea sediment sample collected from the Indian Ocean. The strain was Gram-stain-positive, rod-shaped and salmon pink in colour. Good growth occurred on marine agar with 1–5 % (w/v) NaCl and incubation at 28 °C for more than a fortnight. Sensitive to short ultraviolet radiation. Analysis of 16S rRNA gene sequences revealed that strain SCSIO 08198T had the highest similarity of 97.2 % to Rubrobacter radiotolerans DSM 5868T, and loosely related (<94.2 %) to all other species in the genus Rubrobacter . Phylogenetic analysis based on nearly complete 16S rRNA gene sequences revealed that the novel isolate shared a lineage with members of the genus Rubrobacter . The total cellular fatty acid profile was dominated by C16 : 0 12-methyl. MK-8 was the main menaquinone. The peptidoglycan type was A3α (l-Lys-l-Ala). The major phospholipids were diphosphatidylglycerol, phosphatidylglycerol and unidentified phospholipids. Based on the whole genome sequence analysis, the genome size is 3 078 689 bp with DNA G+C value of 63.8 mol%, including one circular chromosome and two plasmids. Based on these polyphasic data, a new species, Rubrobacter indicoceani sp. nov., is proposed, with the type strain SCSIO 08198T (=DSM 105148T=CGMCC 1.16398T).,
