isolated from freshwater ponds, sewage ditches, and activated sludge.
Morphology
Cells are straight to slightly curved rods (0.4-0.7 × 1-3 µm). Irregularly curved cells up to 15 µm long may occur in older cultures. Most strains show abundant mucous production in all media, which causes the cells to clump together and appear immotile. In young cultures, cells are highly motile by means of polar flagella. Internal photosynthetic membranes appear as small fingerlike intrusions of the cytoplasmic membrane. Cultures grown anaerobically in the light are pale peach to dirty yellowish brown; aerobically grown cells appear colorless to light yellowish brown.
