Abstract

A pink-pigmented, gram-negative, non-motile, non-gliding, flexirubin-negative, rod-shaped and strictly aerobic bacterial strain, designated PTR3T, was isolated from a soil sample from Goyang, South Korea. Growth occurred between 10 and 42 °C (optimum 30 °C), 0–4 % (w/v) NaCl (optimum 0 %) and pH 6–9 (optimum 7–8). Phylogenetic analysis based on 16S rRNA sequences showed that strain PTR3T forms a distinct clade with type strains of the closely related genus, Dyadobacter, with similarities of 93.6 and 91.3–93.6 %, respectively. The strain produces a pink carotenoid pigment(s). The major polar lipids are an unidentified aminophospholipid and an aminolipid. Strain PTR3T was found to contain MK-7 as the predominant menaquinone and C16:1ω7c and/or C16:1ω6c as the major fatty acids. The DNA G + C content of strain PTR3T was deterrmined to be 45.9 mol %. Based on the chemotaxonomic, phylogenetic and other physiological properties, strain PTR3T (=KCTC 42819T = JCM 31133T) is concluded to represent a novel species in a new genus within the family Cytophagaceae, for which the name Telluribacter humicola gen nov., sp. nov., is proposed.
