Table 1. Overview of optimal solution space characterizations with CoPE-FBA for eight different genome-scale metabolic network models11,39,12,16,25,29 for growth on various carbon sources. The calculations in this table were obtained from our CoPE-FBA method described in the Supplementary Information. Unpublished L. lactis, S. thermophilus, L. bulgaricus reconstructions were provided by Prof. B. Teusink (VU University, Amsterdam).
