Pelagibacterium sediminicola sp. nov., isolated from tidal flat sediment
2019
A
Gram-stain-negative,
obligately aerobic, cream-coloured, non-
gliding,
motilewith a single polar
flagellumand rod-shaped bacterium, designated IMCC34151T, was isolated from tidal flat sediment of the Yellow Sea, Republic of Korea. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain IMCC34151T belonged to the genus
Pelagibacteriumof the family
Hyphomicrobiaceaeand shared 94.7–96.8 % sequence similarities to
Pelagibacteriumspecies.
Whole-genome sequencingof strain IMCC34151T revealed a
genome sizeof 3.2 Mbp and a DNA G+C content of 62.6 mol%. The strain contained summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c), C19 : 0cyclo ω8c and C16 : 0 as the major fatty acids and ubiquinone-10 (Q-10) as the major respiratory quinone. The polar lipids detected in the strain were
phosphatidylglycerol, diphosphatidylglycerol, two unidentified
glycolipidsand 12 unidentified lipids. On the basis of its phylogenetic and phenotypic characteristics, strain IMCC34151T is considered to represent a novel species of the genus
Pelagibacterium, for which the name
Pelagibacteriumsediminicola sp. nov. (type strain IMCC34151T =KACC 19595T=NBRC 113420T) is proposed.
