The respiratory quotient (RQ), the specific substrate uptake rate (q_s), the specific productivity (q_p), the efficiency factor (η) and the volumetric productivity of the benchmark strains (overexpressing either HRP or CalB) and the respective benchmark strains co-overexpressing either of the MUT pathway enzymes DAS1, FLD1 or TKL1 were determined
