Luteirhabdus pelagi gen. nov., sp. nov., a novel member of the family Flavobacteriaceae, isolated from the West Pacific Ocean

A Gram-stain-negative, aerobic, and yellow-pigmented bacterium, designated A3-108(T), was isolated from seawater of the West Pacific Ocean. Cells were non-motile and rod-shaped, with carotenoid-type pigments. Strain A3-108(T) grew at pH 6.0–8.5 (optimum 6.5) and 15–40 °C (optimum 28 °C), in the pres...

Sumario:A Gram-stain-negative, aerobic, and yellow-pigmented bacterium, designated A3-108(T), was isolated from seawater of the West Pacific Ocean. Cells were non-motile and rod-shaped, with carotenoid-type pigments. Strain A3-108(T) grew at pH 6.0–8.5 (optimum 6.5) and 15–40 °C (optimum 28 °C), in the presence of 0.5–10% (w/v) NaCl (optimum 1.0%). It possessed the ability to produce H(2)S. Based on the 16S rRNA gene analysis, strain A3-108(T) exhibited highest similarity with Aureisphaera salina A6D-50(T) (90.6%). Phylogenetic analysis shown that strain A3-108(T) affiliated with members of the family Flavobacteriaceae and represented an independent lineage. The principal fatty acids were iso-C(15:0), iso-C(17:0) 3-OH, iso-C(15:1) G, and summed feature 3 (C(16:1)ω7c and/or C(16:1)ω6c). The sole isoprenoid quinone was MK-6. The major polar lipids were phosphatidylethanolamine, one unidentified aminophospholipid, one unidentified aminolipid and one unidentified lipid. The ANIb, in silico DDH and AAI values among the genomes of strain A3-108(T) and three reference strains were 67.3–71.1%, 18.7–22.1%, and 58.8–71.4%, respectively. The G + C content was 41.0%. Distinctness of the phylogenetic position as well as differentiating chemotaxonomic and other phenotypic traits revealed that strain A3-108(T) represented a novel genus and species of the family Flavobacteriaceae, for which the name Luteirhabdus pelagi gen. nov., sp. nov. is proposed (type strain, A3-108(T) = CGMCC 1.18821(T) = KCTC 82563(T)).
