Abstract

A psychrotolerant, Gram-negative, rod-shaped, yellow-pigmented bacterium, designated strain R-S7-29, 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 belongs to the genus (family ‘ ’) with sequence similarity to related members of the genus ranging from 95.2 to 96.7 %. The major fatty acids were Cω5, iso-C 3-OH and summed feature 3 (Cω7 and/or Cω6) and the predominant respiratory quinone was MK-7. The DNA G+C content of strain R-S7-29 was 50 mol%. On the basis of its phenotypic, phylogenetic and chemotaxonomic properties, strain R-S7-29 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is R-S7-29 ( = CCTCC AB 2011022 = NRRL B-59659).
