The intracellular glycogen accumulation was investigated in Chlorobium limicola in dependence of nitrogen and phosphorus concentrations in the medium. Incubation in the media without phosphorus or ammonia provided the highest level of the glycogen in the cells of these bacteria – 80 mg/g of cells. 12 mM of potassium nitrate completely inhibits the uptake of ammonium by the cells of C. limicola.
