Fig. 6From: Engineering and systems-level analysis of Pseudomonas chlororaphis for production of phenazine-1-carboxamide using glycerol as the cost-effective carbon sourceAverage 13C-enrichments calculated using the formula \(\left( {\frac{1}{N}} \right)\sum\nolimits_{i = 1}^{N} {Mi \times i}\), where N is the number of carbon atoms in the metabolite and Mi is the fractional abundance of the ith mass isotopomer. The solid lines (HT66) and dashed lines (HT66LSP) illustrate the measured labeling trendsBack to article page
