title: Dyadobacter sediminis sp. nov., isolated from a subterranean sediment sample.
abstract: A Gram-reaction-negative, flexirubin-type-pigmented, rod-shaped, aerobic, non-motile bacterium, designated strain Z12(T), was isolated from a subsurface sediment sample. In a phylogenetic tree based on 16S rRNA gene sequences, strain Z12(T) formed a distinct clade with the members of the genus Dyadobacter (<96.7 % sequence similarity). The G+C content of genomic DNA was 45.4 %. The major fatty acids of strain Z12(T) were iso-C15 : 0, C16 : 1ω6c and/or C16 : 1ω7c (summed feature 3) and anteiso-C17 : 1 B and/or iso-C17 : 1 I (summed feature 4). The major respiratory quinone was MK-7 and the major polar lipid was phosphatidylethanolamine. On the basis of phenotypic, phylogenetic and genotypic features, strain Z12(T) is considered to represent a novel species, for which the name Dyadobacter sediminis sp. nov., is proposed. The type strain is Z12(T) ( = JCM 30073(T) = CGMCC 1.12895(T)).
