title: Planococcus columbae sp. nov., isolated from pigeon faeces.
abstract: An orange-pigmented, Gram-positive bacterial strain, designated PgEx11(T), was isolated from pigeon faeces. 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 PgEx11(T) contained anteiso-C(15 : 0) as a major cellular fatty acid and MK-7 and MK-8 as the major menaquinones. The DNA G+C content of strain PgEx11(T) 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 PgEx11(T) and these four closely related species was in the range 45.4-16.8 %, respectively. Moreover, strain PgEx11(T) also differs from its close relatives with regard to biochemical and chemotaxonomic characteristics. On the basis of phenotypic, chemotaxonomic and genotypic differences, strain PgEx11(T) represents a novel species of the genus Planococcus, for which the name Planococcus columbae sp. nov. is proposed. The type strain is PgEx11(T) (=MTCC 7251(T)=DSM 17517(T)).
