Flavobacterium phocarum sp. nov., isolated from soils of a seal habitat in Antarctica.
2018
A Gram-stain-negative, yellow-pigmented, non-flagellated, gliding, rod-shaped, oxidase-negative and catalase-positive bacterium, designated SE14T, was isolated from soil on King George Island, South Shetland Islands, Antarctica. Strain SE14T grew at 4–25 °C (optimum, 20 °C), at pH 6.0–9.0 (optimum, pH 7.0–7.5) and with 0–3.0 % NaCl (optimum, 1.0–1.5 %), and could not produce flexirubin-type pigments. 16S rRNA gene sequence analysis showed the the isolate belonged to the genus
Flavobacterium
. Strain SE14T had the highest 16S rRNA gene sequence similarity to
Flavobacterium antarcticum
,
F. tegetincola
and
F. degerlachei
with 95.8, 95.5 and 95.2 %, respectively. The strain SE14T consisted of a clade with
Flavobacterium
noncentrifugens
(16S rRNA gene sequence similarity 94.9 %) and
F. qiangtangense
(16S rRNA gene sequence similarity 94.2 %) and simultaneously formed a distinct phyletic lineage in the neighbour-joining phylogenetic tree. Polar lipids of the strain included phosphatidylethanolamine and four unidentified aminolipids. Strain SE14T contained anteiso-C15 : 0, iso-C15 : 0 and a mixture of iso-C15 : 0 2-OH and/or C16 : 1
ω7c as the main fatty acids, and the only respiratory quinone was menaquinone-6. The genomic DNA G+C content was 42.3 mol%. The polyphasic taxonomic study revealed that strain SE14T belongs to a novel species within the genus
Flavobacterium
, and the name
Flavobacterium
phocarum sp. nov. is proposed. The type strain is SE14T (=CCTCC AB 2017225T=KCTC 52612T).
