title: Dyella jejuensis sp. nov., isolated from soil of Hallasan Mountain in Jeju Island.
abstract: A novel bacterium, designated JP1(T), was isolated from soil of Hallasan Mountain in Jeju Island. The isolate was a Gramnegative, 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 JP1(T) was closely related to Dyella koreensis with 97.6% similarity. Growth of strain JP1(T) occurred at 10-37°C, pH 5-7 and 0-1% (w/v) NaCl. The genomic DNA G+C content of strain JP1(T) 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 JP1(T) were phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, unidentified aminolipids and unidentified aminophospholipids. The DNA-DNA relatedness values between strain JP1(T) and previously reported Dyella species were <10%. Based on phenotypic, genotypic, and phylogenetic distinctness, strain JP1(T) represents a novel species in the genus Dyella, for which the name Dyella jejuensis sp. nov. is proposed. The type strain is JP1(T) (=KACC 17701(T) =JCM 19615(T)).
