Figure 4From: Glucose-methanol co-utilization in Pichia pastoris studied by metabolomics and instationary 13C flux analysisMetabolic flux distribution based on 13C flux analysis using the extended metabolic model. The flux values are given in μmol/gCDW/h. The upper value represents the net flux (in direction of the arrow), the lower value (on blue background) reflects the backward flux (absolute). All fluxes are also listed in Additional file 6.Back to article page
