Vitellibacter aestuarii sp. nov., isolated from tidalflat sediment, and an emended description of the genus Vitellibacter

A Gram-reaction-negative, aerobic, yellowish-orange-pigmented bacterial strain, designated JC2436_T, was isolated from tidal-flat sediment of Oi Island in Korea. Comparative 16S rRNA gene sequence analysis indicated its close affiliation to Vitellibacter vladivostokensis, with 96% sequence similarity to the type strain. Cells grew with 2-6% NaCl and at 10-41 °C. Orange flexirubin pigments were present. The major isoprenoid quinone was MK-6, the DNA G+C content was 48.7 mol% and the predominant fatty acids (>10 %) were iso-C_{15 : 0} and iso-C_{17 : 0} 3-OH. The data obtained from this polyphasic study support the classification of this isolate within a novel species in the genus Vitellibacter, for which the name Vitellibacter aestuarii sp. nov. is proposed. The type strain is JC2436^T (=IMSNU 14137^T =KACC 13727^T =KCTC 22361^T =JCM 15496^T).
