<i>Microbacterium panaciterrae</i> sp. nov., isolated from the rhizosphere of ginseng

다국어 초록 (Multilingual Abstract)

<P>Strain DCY56<SUP>T</SUP> was isolated from a soil sample taken from a ginseng field. The strain was Gram-reaction positive, catalase-positive, oxidase-negative, aerobic and non-motile. Phylogenetic analysis, based on 16S rRNA gene sequence analysis, indicated that strain DCY56<SUP>T</SUP> belonged to the genus <I>Microbacterium</I>. The closest relatives were <I>Microbacterium azadirachtae</I> AI-S262<SUP>T</SUP>, <I>Microbacterium aerolatum</I> V-73<SUP>T</SUP> and <I>Microbacterium phyllosphaerae</I> DSM 13468<SUP>T</SUP> (98.0 %, 98.0 % and 97.5 % gene sequence similarity, respectively). The G+C content of the genomic DNA of strain DCY56<SUP>T</SUP> was 68.5 mol%. The DNA–DNA relatedness values between strain DCY56<SUP>T</SUP> and the most closely related type strains were lower than 36 %. The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol and an unidentified glycolipid. The predominant fatty acids contained iso-C<SUB>16 : 0</SUB>, anteiso-C<SUB>15 : 0</SUB> and anteiso-C<SUB>17 : 0</SUB>. The menaquinones were MK-12 and MK-13. The diagnostic diamino acid of strain DCY56<SUP>T</SUP> was ornithine. The dominant whole-cell sugars were glucose, rhamnose and ribose. The results of the genotypic analysis, in combination with chemotaxonomic and physiological data, demonstrate that strain DCY56<SUP>T</SUP> represents a novel species within the genus <I>Microbacterium</I>, for which the name <I>Microbacterium panaciterrae</I> sp. nov. is proposed. The type strain is DCY56<SUP>T</SUP> ( = KCTC 19884<SUP>T</SUP> = JCM 17839<SUP>T</SUP>).</P>
