Reversible lactate turnover at oscillating oxygen supply in two-compartment cultivation of C. glutamicum. (A) = lactate turnover rates at reference cultivation of C. glutamicum without oscillation (REF), scale-down cultivation with short oscillations (τ = 45 s, TCR1) and scale-down cultivation with long oscillations (τ = 87 s, TCR2); lactate turnover rate qLAC represents the production rate within non-aerated plug flow compartment and equals the lactate uptake rate (rLAC,STR) within aerobic stirred tank compartment (qLAC,PFR = rLAC,STR) with q LAC = c LAC · flow through PFR; (B) = carbon fraction of feed glucose being converted into extracellular lactate [mol C_in_lactate /mol C_in_glucose ] within anaerobic plug flow compartment for experimental condition TCR2.
