Figure 2

Time courses of mass isotopomer distributions of proteinogenic amino acids in fermentation after addition of 13C-labeled glucose, where glutamate production was 20 with respect to glucose uptake of 100. The data (m 0, m 1 ..., m n indicating the mass isotopomer distributions obtained from mass spectral intensity ratios, as previously described [22]) at each sampling time were summed up to unity from the bottom. Time indicates that after 13C glucose addition. The M-57 and M-159 of each amino acid indicate mass ion fragment groups with high intensities, and thus, these data were used for 13C MFA.
