Abstract
A Gram-stain negative, rod-shaped, facultatively aerobic, pale-beige-coloured bacterial strain, designated F7233T, was isolated from coastal sediment sampled at Jingzi Bay, Weihai, PR China. Cells of strain F7233T were 0.3–0.4 µm wide, 1.2–1.4 µm wide long, non-spore-forming and motile with one flagellum. Optimum growth occurred at 30 °C, with 1.0 % (w/v) NaCl and at pH 6.5–7.0. Positive for nitrate reduction, hydrolysis of Tweens and oxidase activity. The sole respiratory quinone of strain F7233T was ubiquinone-10 and the predominant cellular fatty acid was summed feature 8 (C18 : 1
ω7c/C18 : 1
ω6c). The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine and one unidentified aminophospholipid. The G+C content of the chromosomal DNA was 63.3 mol%. Phylogenetic analysis of the 16S rRNA gene sequence revealed that the newly isolate belonged to the genus
Stappia
, with 96.8 % sequence similarity to
Stappia indica
MCCC 1A01226T, 96.1 % similarity to
Stappia stellulata
JCM 20692T and 95.5% similarity to
Stappia taiwanensis
CC-SPIO-10-1T. On the basis of phylogenetic, phenotypic and chemotaxonomic data, it is considered that strain F7233T should represent a novel species within the genus
Stappia
, for which the name Stappia albiluteola sp. nov. is proposed. The type strain is F7233T (=MCCC 1H00419T=KCTC 72859T).
