| Abstract | A novel bacterium, designated JP1T, was isolated from soil of Hallasan Mountain in Jeju Island. The isolate was a Gram- negative, aerobic, motile and rod-shaped (0.2–0.4 × 1.2–2.0 μm) bacterium. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain JP1T was closely related to Dyella koreensis with 97.6% similarity. Growth of strain JP1T occurred at 10–37°C, pH 5–7 and 0–1% (w/v) NaCl. The genomic DNA G+C content of strain JP1T was 62.1 mol%. The major fatty acids were iso-C16:0, iso-C17:1 ω9c, and iso- C15:0. The predominant quinone was ubiquinone-8. The major polar lipids of strain JP1T were phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, uniden-tified aminolipids and unidentified aminophospholipids. The DNA-DNA relatedness values between strain JP1T and pre-viously reported Dyella species were <10%. Based on pheno-typic, genotypic, and phylogenetic distinctness, strain JP1T represents a novel species in the genus Dyella, for which the name Dyella jejuensis sp. nov. is proposed. The type strain is JP1T (=KACC 17701T =JCM 19615T). |
