Metabolic flux ratios in glucose-limited chemostat cultures at different dilution rates of A1) B. subtilis wild type, A2) spo0A and A3) sigE mutant, B1) B. licheniformis T218a (filled symbols) and T380B (open symbols) and B2) B. subtilis natto (open symbols) and B. pumilus (filled symbols). The fraction of serine derived through glycolysis and the fraction of PEP originating from oxaloacetate were obtained from 100% [1-13C]glucose. All other ratios were obtained from experiments with 20% [U-13C]glucose and 80% natural glucose. The experimental error was estimated from redundant mass distribution [20].
