| Zusammenfassung: | <jats:p> <jats:italic>Microbacterium</jats:italic> strains JS53-2<jats:sup>T</jats:sup> and JS53-5 were isolated from sea water in the South Sea of Korea and subjected to phenotypic, chemotaxonomic and genetic characterization. The cells were found to be Gram-positive. These strains contained MK-11 and MK-12 as the main respiratory quinones and anteiso-C<jats:sub>15 : 0</jats:sub>, anteiso-C<jats:sub>17 : 0</jats:sub> and iso-C<jats:sub>16 : 0</jats:sub> as the major cellular fatty acids. The DNA G+C content was 68 mol%. The cell-wall sugars of the isolates were galactose and xylose, and the diamino acid in the cell-wall hydrolysates was lysine. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolates represented an evolutionary lineage distinct from those of other <jats:italic>Microbacterium</jats:italic> species. DNA–DNA reassociation values between the isolates and reference strains <jats:italic>Microbacterium terregens</jats:italic> KCTC 19034<jats:sup>T</jats:sup>, <jats:italic>Microbacterium lacticum</jats:italic> KCTC 9230<jats:sup>T</jats:sup>, <jats:italic>Microbacterium aurum</jats:italic> KCTC 19091<jats:sup>T</jats:sup> and <jats:italic>Microbacterium schleiferi</jats:italic> KCTC 19095<jats:sup>T</jats:sup> were below 23 %. On the basis of evaluation of the morphological, physiological and chemotaxonomic characteristics, 16S rRNA gene sequence comparisons and DNA–DNA hybridizations, a novel species, <jats:italic>Microbacterium koreense</jats:italic> sp. nov., is proposed for these isolates. The type strain is JS53-2<jats:sup>T</jats:sup> (=KCTC 19074<jats:sup>T</jats:sup>=CIP 108696<jats:sup>T</jats:sup>=CCUG 50754<jats:sup>T</jats:sup>).</jats:p> |
