Abstract
Cyclic AMP, theophylline and caffeine promoted sporulation when added to a presporulation medium containing glucose. Caffeine promoted sporulation even when added to a presporulation medium containing acetate as the carbon source, but cyclic AMP and theophylline did not. Caffeine did not increase the intracellular cyclic AMP level, while theophylling did significantly when added to a presporulation medium containing glucose
Caffeine inhibited the vegetative DNA synthesis with little effect on RNA and protein synthesis, resulting in the increase in cell volume, dry weight, and RNA and protein contents, but cyclic AMP and theophylline did not show such effects.
