Abstract
A novel bacterial strain designated CJ70T was isolated from tidal flat sediment in Korea. A polyphasic approach was used to identify this strain taxonomically. The isolate was Gram-stain-negative, strictly aerobic, yellow-pigmented, rod-shaped and non-motile. Phylogenetic analysis of the 16S rRNA gene sequence revealed that strain CJ70T was related most closely to Stakelama pacifica JLT832T with 95.7 % similarity and formed an independent phyletic line from recognized species of the genus Sphingomonas , comprising a clade with Stakelama pacifica , which is the only recognized species of the genus Stakelama . The predominant cellular fatty acids of strain CJ70T were C18 : 1ω7c (60.0 %), C16 : 0 (21.2 %) and C14 : 0 2-OH (5.8 %). The major isoprenoid quinone was ubiquinone-10. The G+C content of the genomic DNA was 61.4 mol%. The results obtained from this study suggested that strain CJ70T represents a novel species of the genus Stakelama , for which the name Stakelama sediminis sp. nov. is proposed. The type strain is CJ70T ( = KACC 16559T = JCM 18079T).
