Analysis of yields of Fps1 from three deletion strains cultured in 2 L bioreactors. Fps1 yields are reported relative to a control sample, which previously represented our highest Fps1 yield obtained , as described in the Methods section. The y-axis shows the factor improvement over the control. Maximum yields are indicated from four immunoblots from duplicate bioreactor cultures. Error bars represent the standard deviation (n = 4). White bars are the values for cells grown in CSM medium, pale grey for CSM medium supplemented with 10 μg/mL myo-inositol and dark grey bars for 2 × CBS medium.
