This strain was identified by using a polyphasic taxonomic approach. The results of 16S rRNA gene sequence analysis showed that strain AS/ASP6 (II)T should be assigned to the genus Planococcus . Chemotaxonomic data (A4α-type peptidoglycan; MK-6, MK-7 and MK-8 menaquinones; mainly branched cellular fatty acids; and phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol as cellular phospholipids) supported taxonomic placement in the genus Planococcus . Phylogenetic analysis of the 16S rRNA gene sequence showed that strain AS/ASP6 (II)T belonged to the genus Planococcus and was closely related to the type strains of Planococcus maritimus (99.1 %) followed by Planococcus rifietoensis (98.6 %), Planococcus maitriensis (98.5 %), Planococcus citreus (98.3 %), Planococcus salinarum (98.1 %), Planococcus columbae (97.9 %), Planococcus donghaensis (97.8 %) and Planococcus antarcticus (97.7 %); DNA–DNA hybridization values obtained were well below the threshold that is required for the proposal of a novel species. The G+C content of the genomic DNA was 51.0 mol%. The phenotypic and genotypic data showed that strain AS/ASP6 (II)T merits recognition as a representative of a novel species of the genus Planococcus , for which the name Planococcus plakortidis sp. nov. is proposed; the type strain is AS/ASP6 (II)T ( = MTCC 8491T = DSM 23997T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.029967-0
