Abstract
The kinetics of growth, extracellular alpha-amylase formation and pool sizes of guanosine polyphosphates (p)ppGpp and adenosine phosphates (ATP and AMP) were determined during discontinuous cultivation of Bacillus subtilis 44. The results indicate a positive involvement of (p)ppGpp in the regulation of the expression of the alpha-amylase gene.
