Analysis of the 16S rRNA gene sequence of the isolate indicated that it had 94.2–98.2 % sequence identity with respect to those of seven recognized species of the genus Planococcus. The strain PgEx11T contained anteiso-C15 : 0 as a major cellular fatty acid and MK-7 and MK-8 as the major menaquinones. The DNA G+C content of strain PgEx11T was 50.5 mol%. Furthermore, analysis of the 16S rRNA gene sequence indicated high levels of similarity with Planococcus rifietoensis (98.2 %), Planococcus maitriensis (97.6 %), Planococcus citreus (97.5 %) and Planococcus maritimus (97.1 %). However, the mean value for DNA–DNA relatedness between PgEx11T and these four closely related species was in the range 45.4–16.8 %, respectively. Moreover, strain PgEx11T also differs from its close relatives with regard to biochemical and chemotaxonomic characteristics. On the basis of phenotypic, chemotaxonomic and genotypic differences, strain PgEx11T represents a novel species of the genus Planococcus, for which the name Planococcus columbae sp. nov. is proposed. The type strain is PgEx11T (=MTCC 7251T=DSM 17517T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.64742-0
