Abstract

A novel bacterial strain, NH131(T), was isolated from deep-sea sediment of South China Sea. Cells were strictly aerobic, Gram-stain negative, short rod-shaped and motile with a single lateral flagellum. Strain NH131(T) grew optimally at pH 6.5-7.0 and 25-30 °C. 16S rRNA gene sequence analysis revealed that strain NH131(T) belonged to the genus Devosia, sharing the highest sequence similarity with the type strain, Devosia geojensis BD-c194(T) (96.2%). The predominant fatty acids were C(18 : 1)ω7c, 11-methyl C(18 : 1)ω7c, C(18 : 0) and C(16 : 0). Ubiquinone 10 was the predominant ubiquinone. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phospholipid, three glycolipids and two unknown lipids. The DNA G+C content of strain NH131(T) was 63.0 mol%. On the basis of the results of polyphasic identification, it is suggested that strain NH131(T) represents a novel species of the genus Devosia for which the name Devosia pacifica sp. nov. is proposed. The type strain is NH131(T) ( = JCM 19305(T) = KCTC 32437(T)).
