Cells of the strain were Gram-negative, strictly aerobic, rod-shaped and motile. Phylogenetic analysis of the 16S rRNA gene indicated that this bacterium belongs to the γ-subclass of Proteobacteria within the genus Pseudomonas and that the closest related species is Pseudomonas graminis. The strain produced catalase but not oxidase. Cellulose, casein, starch, gelatin and urea were not hydrolysed. Aesculin was hydrolysed. Growth was observed with many carbohydrates as carbon sources. The main non-polar fatty acids detected were hexadecenoic acid (16 : 1), hexadecanoic acid (16 : 0) and octadecenoic acid (18 : 1). The hydroxy fatty acids detected were 3-hydroxydecanoic acid (3-OH 10 : 0), 3-hydroxydodecanoic acid (3-OH 12 : 0) and 2-hydroxydodecanoic acid (2-OH 12 : 0). The G+C DNA content determined was 59·3 mol%. DNA–DNA hybridization showed 48·7 % relatedness between strain OK2T and P. graminis DSM 11363T and 26·2 % with respect to Pseudomonas rhizosphaerae LMG 21640T. Therefore, these results indicate that strain OK2T (=LMG 21974T=CECT 5822T) belongs to a novel species of the genus Pseudomonas, and the name Pseudomonas lutea sp. nov. is proposed. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.02966-0
