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 μ mol and mg per CDW, respectively.
