Morphology | Prosthecomicrobium |
CELLULAR |
Staining | Gram-negative |
Morphology | Unicellular bacterium with coccobacillary to rod-shaped cells ranging in diameter from 0.8 to 1.2 um and containing numerous prosthecae extending from all locations on the cell surface |
Motility | Motile and nonmotile species exist. Motile organisms produce a single polar to subpolar flagellum |
Specialized structures | Prosthecae which may number from 10 to more than 30/cell are typically short (i.e. < 1.0 um in length); some species, however, also produce longer prosthecae (> 2.0 um). Cells divide by budding. Buds are produced directly from the mother cell, never from tips of prosthecae.. one species forms gas vacuoles but not flagella |
