Accumulation of endotoxin (lipid A of lipopolysaccharide layer) and cAMP as a function of cultivation time. The specific growth rate is indicated in the figure by a dashed line. A. Volumetric accumulation of cAMP and endotoxin compared to CDW accumulation. The arrow indicates an addition of magnesium sulphate. B. Accumulation of cAMP and endotoxin in μmol and mg per CDW, respectively.
