intracellular substrates for endogenous metabolism during long-term starvation of rod and spherical cells of arthrobacter crystallopoietes.cells of arthrobacter crystallopoietes, harvested during growth as spheres and as rods, were starved by shaking at 30 c in phosphate buffer for 30 days, during which time they maintained 100% viability. changes in cellular components and the activity of specific enzyme pathways were monitored. a glycogen-like polysaccharide comprised 40% of the dry weight of growing spherical cells and 10% of the dry weight of rod cells. this material was utilized at approximately the same rate, on a percentage ...19705474876
