Sphingorhabdus pacificus sp. nov., isolated from sandy sediments of the Sea of Japan seashore

An aerobic, Gram-negative, yellow-pigmented, non-motile rod-shaped bacterium designated KMM 9574ᵀwas isolated from a sand sediment sample collected from the Sea of Japan seashore. Comparative 16S rRNA gene sequence analysis showed that strain KMM 9574ᵀbelonged to the genus Sphingorhabdus sharing a highest sequence similarity to Sphingorhabdus marina JCM 14161ᵀ96.8 %. Strain KMM 9574ᵀwas characterized by the major ubiquinone Q-10, and by the predominance of C₁₈:₁ω7c, C₁₆:₀2-OH, C₁₆:₁ω7c, C₁₇:₁, followed by C₁₅:₀2-OH and C₁₄:₀2-OH in its fatty acid profile. Polar lipids consisted of phosphatidylcholine, sphingoglycolipid, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unknown phospholipid, and an unknown lipid. The DNA G+C content was 56.5 mol %. Based on phylogenetic analysis and distinctive phenotypic characteristics, strain 9574ᵀis concluded to represent a novel species of the genus Sphingorhabdus, for which the name Sphingorhabdus pacificus sp. nov., is proposed. The type strain of the species is strain KMM 9574ᵀ(= NRIC 0922ᵀ = JCM 30177ᵀ).
