CELLULAR |
Staining | Gram-negative |
Morphology | Cells of widely varying sizes occur mostly in filaments. Filaments usually demonstrate flexing or bending and usually can be considered as distinct multicellular units |
Motility | When in contact with a substrate, the motile organisms glide over the surface in a slow wavy type of motion. No flagella or other motility organelles are proven. Gliding motility is usually in a direction parallel with the length of the filaments. |
Specialized structures | Colourless; chlorophyll, phycobiliproteins, and carotenoid pigments are not produced. Multiplication is by transverse binary fission of both singly occurring cells and cells throughout the length of filaments. Cells within filaments may be visible or not visible. Filament dispersion may be via disintegration or sacrificial cell death. Sheaths and holdfasts may be formed. Resting cell forms not known. Sulfur is deposited in the presence of hydrogen sulfide. Poly-B-hydroxybutyric acid (PHB) and polyphosphate (volutin) often occur |
