Abstract
- A bacterium that was Gram-staining-positive, facultatively anaerobic, non-motile, rod- or filamentous-shaped, designated as strain 2JSPR-7 <superscript>T</superscript> , was isolated from a gut of larvae of Allomyrina dichotoma which were raised at the National Institute of Agricultural Sciences, Wanju-gun, Republic of Korea. 2JSPR-7 <superscript>T</superscript> had the highest 16S rRNA gene sequence similarity to Xylanibacterium ulmi XIL08 <superscript>T</superscript> (98.1 %), Xylanimicrobium pachnodae NBRC 107786 <superscript>T</superscript> (97.8 %) and Xylanimonas cellulosilytica DSM 15894 <superscript>T</superscript> (97.5 %). Optimum growth conditions were at 28-30 °C, pH 7-8 and 0 % salt concentration. The cellular fatty acids mainly consisted of anteiso-C <subscript>15 : 0</subscript> , C <subscript>14 : 0</subscript> and C <subscript>16 : 0</subscript> . The polar lipids were diphosphatidylglycerol, four unidentified phospholipids and two unidentified glycophospholipids. The major menaquinones were MK-8(H <subscript>4</subscript> ) and MK-9(H <subscript>4</subscript> ). The peptidoglycan structure was suggested to be the type A3 α (A11.14) l-Lys-l-Ser with the presence of d-Ala, l-Ala, d-Glu, l-Ser and l-Lys. Whole cell sugars were rhamnose, ribose and glucose. The DNA G+C content was 72.7 mol%. We encountered difficulty in selecting a suitable genus to accommodate strain 2JSPR-7 <superscript>T</superscript> from any of the genera Xylanimonas , Xylanimicrobium and Xylanibacterium based on the polyphasic approach including phylogenetic and phenotypic characterization. Therefore, it is proposed to combine the genera Xylanimicrobium and Xylanibacterium with the genus Xylanimonas considering the priority of publication and to classify strain 2JSPR-7 <superscript>T</superscript> in the genus as Xylanimonas allomyrinae sp. nov. The type strain of the novel species is 2JSPR-7 <superscript>T</superscript> (=KACC 19330 <superscript>T</superscript> =NBRC 113052 <superscript>T</superscript> ). In addition, the description of the genus Xylanimonas is emended, and Xylanibacterium ulmi and Xylanimicrobium pachnodae are reclassified as Xylanimonas ulmi comb. nov. and Xylanimonas pachnodae comb. nov., respectively.
