| Morphology | Caseobacter polymorphus |
| CELLULAR |
| Staining | Gram positive |
| Morphology | Irregular rods become ovoid or coccoid in shape with the exhaustion of the medium. After transferring the cells to a fresh medium outgrowths from the coccoid and ovoid cells occur, which result in the formation of rods. The cells occur singly, in pairs with a typical V formation and in palisades |
| Motility | non motile |
| Specialized structures |
| Division |
| COLONIAL |
| Solid surface | On yeast extract, 0.7% (w/v) glucose 1%(w/v) agar colonies have a dry appearance, are small 2-3 mm circular convex and are grey-white, slightly pink or slightly red. |
