Fig. 4From: Engineering cascade biocatalysis in whole cells for bottom-up synthesis of cello-oligosaccharides: flux control over three enzymatic steps enables soluble productionProduct composition of single plasmid-based whole-cell catalysts after 8 h of conversion. Soluble COS are separated by their degree of polymerization (DP 2–6). Insoluble COS production was calculated based on the molar balance between glucose units incorporated as primer in soluble COS and the actually consumed glucose unitsBack to article page
