Morphology | Aminobacter |
CELLULAR |
Staining | Gram negative |
Morphology | rod shpaed with rounded ends (0.5-0.9 x 1.0-3.0 um) |
Motility | subpolar flagella |
Specialized structures | granules of poly- beta-phydroxybutyric acid accumulate in the cells |
Division | budding |
COLONIAL |
Solid surface | colonies are white to light yellos |
Liquid | abundant growth in nutrient broth and PYG broth, no water soluble fluorescent pigments are produced |
