Abstract

An orange-pigmented, Gram-positive bacterial strain, designated PgEx11, 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 . The strain PgEx11 contained anteiso-C as a major cellular fatty acid and MK-7 and MK-8 as the major menaquinones. The DNA G+C content of strain PgEx11 was 50.5 mol%. Furthermore, analysis of the 16S rRNA gene sequence indicated high levels of similarity with (98.2 %), (97.6 %), (97.5 %) and (97.1 %). However, the mean value for DNA–DNA relatedness between PgEx11 and these four closely related species was in the range 45.4–16.8 %, respectively. Moreover, strain PgEx11 also differs from its close relatives with regard to biochemical and chemotaxonomic characteristics. On the basis of phenotypic, chemotaxonomic and genotypic differences, strain PgEx11 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is PgEx11 (=MTCC 7251=DSM 17517).
