Adhaeribacter soli sp. nov., a bacterium isolated from soil in Korea.

ABSTRACT

Strain MA2T was isolated from a soil sample from Gijang-gun, Busan in Korea. The strain, a Gram-stain-negative aerobic bacterium, is non-motile, ovoid- or rod-shaped, catalase- and oxidase-positive, and grows at NaCl concentrations 1% (w/v), at 15-30 °C (optimum 25 °C) and at pH 6-8.5 (optimum pH 7.5). The 16S rRNA gene sequence indicates that it belongs to the genus Adhaeribacter in the family Hymenobacteraceae. Phylogenetically, its closest relatives are Adhaeribacter terrae HY02T and Adhaeribacter terreus DNG6T, to which the strain shows 16S rRNA gene sequence similarity values of 96.6 and 96.0%, respectively. The major fatty acids (> 5% of the total fatty acids) of strain MA2T are C150 iso, C150 iso-G and summed feature 4 (anteiso-C171 B and/or iso-C171 I). The only detected isoprenoid quinone of strain MA2T is MK-7. The major polar lipid was phosphatidylethanolamine. The draft genome sequence of strain MA2T has a size of 4.9 Mkb. The genomic DNA G + C content was 46.9 mol%. Based on the phylogenetic, genotypic, phenotypic and chemotaxonomic data, the strain represents a novel species of the genus Adhaeribacter, for which the name Adhaeribacter soli sp. nov. is proposed. Strain MA2T (= KCTC 72630T = NBRC 114192T) is the type strain.
