Figure 1: The distribution of the measured data matrix of 329 rows and 8 columns, corresponding to a dataset consisting of 329 mutant strains and 8 variables.

These variables are butanol productivity (g/L/h), butanol yield (g/g), solvent (ABE) yield (g/g), acetone yield (g/g), ethanol yield (g/g), maximal specific growth rate (added butyrate: 5.0 g/L; μMax-A), maximal specific growth rate (added butyrate: 6.5 g/L; μMax-B), and maximal specific growth rate (added butyrate: 8.5 g/L; μMax-C).
