Fig. 6: Effects of initial amounts of base nutrients on the overall biomass yield.

A, B The produced biomass as function of initial nutrient amount of aspartate for different initial amounts of the base nutrient ((A) – glucose, (B) – acetate). Data points are average of three biological replicates and error bars are standard error that are too small to notice. Curves are linear fits to the average of the three replicates in the linear regions (fit parameter R² > 0.9). C, D The overall biomass yield as function of initial nutrient amount as calculated from the conditions in (A, B) respectively. Black data points show the slope of the first linear phase and blue data points show the second. Curves show linear fit (fit parameter R² > 0.9 for first linear fit on acetate and second linear phase on glucose, the other fits show a good fit to a constant (p < 0.05)). Error bars depict error of fit parameter.
