The levels of intracellular adenine nucleotides, energy charge, oxygen consumption and poly‐β‐hydroxybutyric acid stored, have been investigated in dry vegetative cells and cysts of Azotobacter vinelandii . The data show that under desiccation conditions the cysts retain viability at energy charge values of 0.20 and an ATP/ADP ratio of 0.24, whereas under the same desiccation conditions, vegetative cells die at energy charge values <0.5 and an ATP/ADP ratio of <0.6.
