| Popis: | A facultatively anaerobic and Gram-stain-negative bacterium, strain GY_GT, was isolated from a river (Daedeock-cheon) in Daejeon, Republic of Korea. The isolate was catalase-positive, oxidase-positive and formed yellow colonies. Strain GY_GT was phylogenetically classified as belonging in the genus Sphingorhabdus. Its closely related strains were Sphingorhabdus wooponensis 03SU3-PT (97.1 % similarity), Sphingorhabdus buctiana T5T (96.9 %), Sphingorhabdus contaminans JC216T (96.5 %), Sphingorhabdus rigui 01SU5-PT (96.5 %) and Sphingorhabdus planktonica G1A_585T (96.3 %) based on 16S rRNA gene sequences. The growth conditions for GY_GT were at 10–45 °C (optimum, 25 °C), pH 6–10 (pH 7) and 0–4% NaCl (0.5–1.5 %). Strain GY_GT could utilize turanose, d-fructose-6-phosphate, glucuronamide, α-keto-glutaric acid and acetoacetic acid. The major fatty acids of strain GY_GT were summed features 8 (C18 : 1 ω7c/C18 : 1 ω6c; 40.6 %) and 3 (C16 : 1 ω6c/C16 : 1 ω7c; 24.7 %). The major quinone required for respiration was Q-10. The polar lipids of strain GY_GT were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and sphingolipid. The G+C content of the genome was 57.7 mol%. The average nucleotide identity and average amino acid identity values between strains GY_GT and S. wooponensis were 71.0 and 72.7 %, respectively. Based on phylogenetic and phenotypic attributes, we suggest that strain GY_GT is a novel species in the genus Sphingorhabdus and propose the name Sphingorhabdus pulchriflava. The type strain is GY_GT (=KCTC 62791T=JCM 32855T). |
