An aerobic, Gram-negative, motile, rod-shaped bacterium designated KMM 9500ᵀwas isolated from a sediment sample collected from the Sea of Japan seashore. Comparative 16S rRNA gene sequence analysis affiliated strain KMM 9500ᵀto the genus Pseudomonas as a distinct subline clustered with Pseudomonas marincola KMM 3042ᵀand Pseudomonas segetis KCTC 12331ᵀsharing the highest similarities of 98 and 97.9 %, respectively. Strain KMM 9500ᵀwas characterized by mainly possessing ubiquinone Q-9, and by the predominance of C₁₈:₁ω7c, C₁₆:₁ω7c, and C₁₆:₀followed by C₁₂:₀in its fatty acid profile. Polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unknown aminophospholipid, and unknown phospholipids. Strain KMM 9500ᵀwas found to inhibit growth of Gram-negative and Gram-positive indicatory microorganisms. Based on the phylogenetic analysis and distinctive phenotypic characteristics, strain 9500ᵀis concluded to represent a novel species of the genus Pseudomonas, for which the name Pseudomonas glareae sp. nov. is proposed. The type strain of the species is strain KMM 9500ᵀ(=NRIC 0939ᵀ).
