Chung, Eu Jin and Jo, Eun Ju and Yoon, Hwan Sik and Song, Geun Cheol and Jeon, Che Ok and Chung, Young Ryun,, 61, 2389-2394 (2011), doi = https://doi.org/10.1099/ijs.0.023846-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= Two Gram-reaction-negative, yellow–orange-pigmented, rod-shaped bacterial strains, designated YC6722T and YC6723T, were isolated from rhizosphere soil samples collected from rice fields in Jinju, Korea. Strains YC6722T and YC6723T grew optimally at 25–30 °C and at pH 7.0–8.5. Phylogenetic analyses of 16S rRNA gene sequences showed that strain YC6722T was most closely related to Sphingomonas jaspsi TDMA-16T (96.6 % sequence similarity) and strain YC6723T was related most closely to Sphingomonas aquatilis JSS7T (96.9 %). The two strains contained ubiquinone-10 (Q-10) as the major respiratory quinone system and sym-homospermidine as the major polyamine. The G+C contents of the genomic DNA of strains YC6722T and YC6723T were 63.3 and 61.0 mol%, respectively. The major fatty acid was C18 : 1ω7c. The polar lipids detected in the two strains were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, sphingoglycolipid, phosphatidyldimethylethanolamine and other unknown lipids. On the basis of their phylogenetic positions, and their biochemical and phenotypic characteristics, strains YC6722T and YC6723T represent two novel species of the genus Sphingomonas, for which the names Sphingomonas oryziterrae sp. nov. ( = KCTC 22476T  = DSM 21455T) and Sphingomonas jinjuensis sp. nov. (KCTC 22477T  = DSM 21457T) are proposed., language=, type=
