Luteimicrobium xylanilyticum sp. nov., isolated from the gut of a long-horned beetle, Massicus raddei

Abstract

A novel strain, designated W-15T, was isolated from the gut of a long-horned beetle, Massicus raddei, collected in South Korea. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the strains belonged to the suborder Micrococcineae . Strain W-15T was most closely related to Luteimicrobium album RI148-Li105T (97.9 % similarity). Strain W-15T was Gram-stain-positive, rod- and coccus-shaped and non-motile. Growth was observed at 15–37 °C, at pH 4.5–8.5 and in the presence of 0–5.0 % NaCl. The cell-wall peptidoglycan of the strain was A4α (l-Lys–d-Ser–d-Asp). The major menaquinone present in this strain was MK-8 (H2) and the major cellular fatty acids were anteiso-C15 : 0, iso-C16 : 0, iso-C15 : 0 and anteiso-C17 : 0. The major polar lipids were diphosphatidylglycerol, phosphatidylinositol, an unknown lipid, an unknown phospholipid and an unknown phosphoglycolipid. The G+C content of genomic DNA of the strain was 73.8 mol%. On the basis of evidence from our polyphasic taxonomic study, strain W-15T is classified as representing a novel species in the suborder Micrococcineae , for which the name Luteimicrobium xylanilyticum sp. nov. is proposed. The type strain of this species is strain W-15T ( = KCTC 19882T = JCM 18090T).
