Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain LMO-1T belonged to genus Sphingomonas , with the highest sequence similarity to Sphingomonas formosensis CC-Nfb-2T (96.3 %), followed by Sphingomonas prati W18RDT (96.1 %), Sphingomonas arantia 6PT (96.0 %) and Sphingomonas montana W16RDT (95.9 %). The predominant polar lipids were phosphatidylethanolamine, sphingoglycolipid, phosphatidylglycerol and phosphatidylcholine. The main cellular fatty acids were summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c), C16 : 0 and C14 : 0 2-OH. The major polyamine was sym-homospermidine and the predominant isoprenoid quinone was ubiquinone-10. The genome DNA G+C content of strain LMO-1T was 69.2 mol%. The average nucleotide identity and DNA–DNA hybridization values between strain LMO-1T and CC-Nfb-2T were 75.9 and 20.5 %, respectively. Based on these data, LMO-1T should be classified as representing a novel species of the genus Sphingomonas , for which the name Sphingomonas profundi sp. nov. is proposed. The type strain is LMO-1T (=MCCC 1K04066T=JCM 33666T).", }
