Dynamic incorporation of [U-13
C]-glucose into target metabolites. The abscissa and vertical axes represent the cultivation time of C. cellulovorans and the relative fraction of indicated labeled compounds. ' + 1', ' + 2', ' + 3', ' + 4', ' + 5', and ' + 6' mean the number of 13-carbon isotope in each metabolite incorporated from [U-13C]-glucose. Error bars represent standard deviations.
