| Morphology | Prosthecobacter fusiformis |
| CELLULAR |
| Staining | Gram- negative |
| Morphology | Cells fusiform or vibrio-shaped, 0.5-0.9 x 2.5 um, exclusive of appendages. Each cell bears at least one polar prostheca of a type unique to this genus |
| Motility | Nonmotile |
| Specialized structures | . Prosthecal diameter is 0.1-0.2 um, tapering gently away from the cell pole but typically with a bulbous distal tip, which is adhesive. Interior of the prostheca is a continuation of the protoplast, including cytoplasmic membrane and ribosomes. Binary fission is constrictive and is completed without formation of a septum. Prostheca development occurs at the younger pole as the cell grows; at the time of fission, each progeny cell bears a single polar prostheca, so that cell division is morphologically symmetrical.. |
| Division |
| COLONIAL |
| Solid surface | Colonies circular, convex, glistening, with smooth margin; butyrous in texture; may be colourless or pale yellow. |
| Liquid | Growth in agitated liquid culture is evenly dispersed |
| Growth Parameters | Prosthecobacter fusiformis |
| PHYSIOLOGICAL |
| Tropism | Chemoorganotrophic and oligotrophic |
| Oxygen | Strictly aerobic |
| pH | Optimal pH: near neutrality; range tolerated: 6.6- 8.2 for the type strain |
| Temperature | Optimal temperature for growth: 20-30`C; tolerated range for any isolate is wide, with lows ranging from 1-10`C and with highs ranging from 35`40`C. |
| Requirements | grow readily in complex media containing <0.1% (w/v) organic material. Exogenous organic micronutrients not required. Sugars are the only generally utilized carbon sources |
