Phylum Proteobacteria, Class Gammaproteobacteria, Order Pseudomonadales, Family Pseudomonadaceae, Genus Pseudomonas,
Pseudomonas citronellolis Seubert 1960.
Gram-negative, 0.5 x 1-1.5 μm rods, motile by a polar single flagellum.
Transparent, raised circular colonies with slightly wrinkled edges. Hemolysis is
produced on defibrinated rabbit blood agar.
Obligately aerobic (grows anaerobically only in the presence of nitrate), optimal
growth temperature 30 ºC. Can grow at 41 ºC. Uncertain growth at 4 ºC (positive
according to Prakash et al. 2007 and negative according to Elke Lang et. al 2007).
Grows on media: Trypticase Soy Agar, Nutrient agar, LB medium, MacConkey agar.
The species shows positive reactions for growth in the presence of 5% NaCl.
Isolated from oil sludge, soil.

citronellol as sole carbon source).
