Morphology

Comamonas

CELLULAR

Staining	Gram negative
Morphology	straight or slightly curved rods (0.5-1.0 x 1-4 um) that occur singly or in pairs
Motility	motile by means of a tuft of polar flagella
Specialized structures	poly beta hydroxyburtrate granules are accumulated within the cells

Division

COLONIAL

Solid surface

no fluorescent pigments produced

Growth Parameters

Comamonas

PHYSIOLOGICAL

Tropism	chemoorganotroph
Oxygen	strict aerobe respiratory metabolism
pH
Temperature
Requirements	good growth on media with organic acids, amino acids or peptone
Products
Enzymes	oxidase positive, catalase positive
Unique features	carbohydrates are rarely attacked. The major cellular fatty acids are hexadecanoic acid (16:0), hexadecenic acid (16:1) and octadecanic acid (18:1) Cells always contain 3-hydroxydecanoic acid (3-OH 10:0). The major quinone is Q-8. Menaquinone is not produced
