Peptide abundance in cells harvested from mid-exponential anaerobic shake-flask cultures of strains IMX585 (CEN.PK reference), IMU033 (pGAL1-prk cbbm), and IMX774 (pDAN1-prk cbbm), displayed as the sum of LC–MS peak areas of unique peptides identified per protein. a Act1 (internal control); b CbbM; c PRK. Cultures of IMX585 and IMX774 were grown on 20 g L⁻¹ glucose (initial pH 6); cultures of IMU033 were grown on 20 g L⁻¹ galactose (initial pH 6). Values represent averages ± mean deviations of measurements on independent duplicate cultures
