The effect of a low phosphate concentration on intracellular adenine nucleotides, oxygen consumption and poly‐β‐hydroxybutyric acid synthesis, was investigated with batch cultures of Bacillus megaterium . At low phosphate concentrations the cells contained much larger amounts of poly‐β‐hydroxybutyric acid, but displayed lower adenylate energy charge and oxygen uptake than did control cells. The ratio of ATP to ADP was much greater in the control cells. The levels of ATP and AMP were lower in low‐phosphate cells.
