| Popis: | A Gram-stain-negative and strictly aerobic bacterial strain, designated 6-4T, was isolated from forest soil in Jeju island, South Korea. Cells showing oxidase-positive and catalase-negative reactions were thin and long non-motile rods. Growth of strain 6-4T was observed at 20–35 °C (optimum, 30 °C) and pH 6.0–9.0 (optimum, pH 7.0). Strain 6-4T contained iso-C15 : 0, anteiso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH as the major fatty acids and menaquinone-7 (MK-7) as the sole isoprenoid quinone. Phosphatidylethanolamine was the major polar lipid and five unidentified aminolipids, one unidentified aminophospholipid and one unidentified lipid were also detected as minor polar lipids. The G+C content of the genomic DNA was 45.8 mol%. Strain 6-4T was most closely related to Flavihumibacter solisilvae 3-3T with a low 16S rRNA gene sequence similarity (94.2 %) and phylogenetic analysis indicated that the strain formed a distinct phylogenetic lineage from members of the genus Flavihumibacter and other closely related genera. On the basis of phylogenetic inference and phenotypic, chemotaxonomic and molecular properties, strain 6-4T represents a novel species of a new genus of the family Chitinophagaceae , for which the name Niveitalea solisilvae gen. nov., sp. nov. is proposed. The type strain of Niveitalea solisilvae is 6-4T (=KACC 18808T=JCM 31525T). An emended description of the genus Flavihumibacter is also proposed. |
