A Gram-negative, rod-shaped, aerobic, yellow-pigmented strain LRR22T, was isolated from proglacial lake sediment in the Arctic area.Sequence analysis of 16S rRNA gene of strain LRR22T showed relationships to the genera Sphingomonas (91.9%-95.7%), Sphingopyxis (95.3%-93.4%) and Novosphingobium (94.5%-92.2%).Strain LRR22T contained Q-10 as the ubiquinone and C18:1 ω7c (11.5%), Summed feature 3 (C16:1 ω7c and/or C16:1 ω 6c, 26.7%), C16:0 (10.9%) as the dominant fatty acids.
