A Gram-negative, aerobic, rod-shaped bacterium, designated DM2-R-LB4T was isolated from Cannabis sativa L. ‘Cheungsam’ in Andong, Republic of Korea. The strain DM2-R-LB4T grew at temperatures of 15?45?°C (optimum, 30?37?°C), pH of 5.5?9 (optimum, 8.0), and 0?2?% (w/v) NaCl concentration (optimum, 0%). Phylogenetic analyses based on the 16S rRNA gene sequences revealed that strain DM2-R-LB4T is related to species of the genus Sphingomonas, and shared 97.8 and 97.5% similarity to Sphingomonas kyenggiensis KCTC 42244T and Sphingomonas leidyi DSM 4733T, respectively. The DNA G+C content was 67.9?mol% and genome analysis of the strain DM2-R-LB4T revealed that the genome size was 4?386?171?bp and contained 4?009 predicted protein-coding genes. The average nucleotide identity (ANI) values between strain DM2-R-LB4T and S. kyenggiensis KCTC 42244T, and S. leidyi DSM 4733T was 76.8 and 76.7?%, respectively, while the values of digital DNA?DNA hybridization (dDDH) were 20.7 and 20.6?%, respectively. C14?:?0 2-OH, C16?:?0, and summed feature 8 (C18?:?1?ω6c and/or C18?:?1?ω7c) were the major fatty acids (>10?%) in the strain DM2-R-LB4T. The polar lipids comprised diphosphatidylglycerol (DPG), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), phosphatidylcholine (PC), sphingoglycolipid (SGL), glycolipid (GL), phospholipid (PL), and two unidentified polar lipids (L1 and L2). Ubiquinone-10 (Q-10) was the only respiratory quinone. The polyamine pattern was found to contain homospermidine, putrescine, and spermidine. The results of phylogenetic anlayses, polyphasic studies, revealed that strain DM2-R-LB4T represents a novel species of the genus Sphingomonas, for which the name Sphingomonas cannabina sp. nov., is proposed. The type strain is DM2-R-LB4T (=KCTC 92075T = GDMCC 1.3018T).
