Dyadobacter arcticus sp. nov., isolated from Arctic soil.
A psychrotolerant, Gram-negative, rod-shaped, yellow-pigmented bacterium, designated strain R-S7-29(T), was isolated from a soil sample collected from the Svalbard Archipelago in Norway (78° N). Cells were non-motile, aerobic, and catalase- and oxidase-positive. Growth occurred at 4-28 °C (optimum, 18 °C). A phylogenetic tree based on 16S rRNA gene sequences showed that strain R-S7-29(T) belongs to the genus Dyadobacter (family 'Flexibacteraceae') with sequence similarity to related members of the genus ranging from 95.2 to 96.7 %. The major fatty acids were C16 : 1ω5c, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and the predominant respiratory quinone was MK-7. The DNA G+C content of strain R-S7-29(T) was 50 mol%. On the basis of its phenotypic, phylogenetic and chemotaxonomic properties, strain R-S7-29(T) represents a novel species of the genus Dyadobacter, for which the name Dyadobacter arcticus sp. nov. is proposed. The type strain is R-S7-29(T) ( = CCTCC AB 2011022(T) = NRRL B-59659(T)).
