Abstract

An aerobic, rod-shaped, Gram-positive, oxidase-negative, catalase-positive bacterial isolate, strain FCC-01(T), originating as a contaminant of hairspray was characterized using phenotypic and molecular taxonomic methods. A 16S rRNA gene sequence analysis revealed that the isolate belonged to the genus Microbacterium and represented an evolutionary lineage that was distinct from recognized Microbacterium species. Cell-wall hydrolysate from the isolate contained ornithine and the cell-wall sugars consisted of rhamnose and galactose. The main respiratory quinones were MK-12 (38 %) and MK-11 (35 %). The major cellular fatty acids were anteiso-C(15 : 0) (48 %), anteiso-C(17 : 0) (35 %) and iso-C(16 : 0) (11 %). The DNA G+C content was 69 mol%. The isolate showed <98 % 16S rRNA gene sequence similarity with respect to all of the Microbacterium species with validly published names. On the basis of the morphological, physiological and chemotaxonomic data and the results of the comparative 16S rRNA gene sequence analysis, this isolate represents a novel species of the genus Microbacterium, for which the name Microbacterium hatanonis sp. nov. is proposed. The type strain is FCC-01(T) (=JCM 14558(T) =DSM 19179(T)).
