Data and analysis from medium optimization experiments. a Spread of data representing the β-carotene titer and yield/DCW percent improvement relative to strains grown in the base (YNB only) medium. Each shape and color represents a separate medium condition (labels not shown due to visual limitations, see Additional file 1); b The feature ranking of the medium components on the predictive power of the gradient boosted tree machine learning model; c Comparison of the β-carotene titers achieved for the YNB medium and YNB(+) medium in 25 mL shake flask (YNB medium was supplemented with an additional 2 g/L glucose to match the primary carbon source concentrations); d β-carotene titers achieved in bench-top fermenter using a YPD medium (error bars represent measurement variations)
