Abstract

A psychrotolerant, Gram-stain-positive, yellow-pigmented, aerobic rod, designated SK1, was isolated from a soil sample collected from Store Koldewey, north-east Greenland. Cells were catalase- and methyl red-positive, produced HS and produced acid from glucose, mannitol and salicin. Strain SK1 was able to grow between −6 and 28 °C, with an optimum at 20 °C. The isolate contained 2,4-diaminobutyrate, glycine, alanine and glutamic acid in the cell wall and the major menaquinones were MK-10 and MK-11. Identified polar lipids were phosphatidylglycerol and diphosphatidylglycerol. The major fatty acids were anteiso-C (53.5 %), anteiso-C (17.0 %) and C (12.1 %). The genomic DNA G+C content was 67.8 mol%. Strain SK1 showed the highest 16S rRNA gene sequence similarity with 0549 (97.6 %) and RuGl7 (96.8 %). Considering morphological, physiological, biochemical and chemotaxonomic characters and phylogenetic analysis, strain SK1 represents a novel species in the genus , for which the name sp. nov. is proposed. The type strain is SK1 ( = DSM 22823  = NCCB 100316).
