Fermentation traces for i, ii: dissolved oxygen (DO), iii, iv: power per unit volume (P/V), v, vi: air flow rate (VVM), vii, viii: oxygen flow rate (VVM), ix, x: pH and xi, xii: volume of base added (% (v/v)) for cascade A (air/stirrer speed/O2) and cascade B (air/O2/stirrer speed) and for ambr 15f (▪, red) and Multifors (□, black).

For each cascade: n = 12 ambr 15f vessels and n = 2 Multifors vessels. N.B. No error bars shown for Multifors traces, cascade A after 20 h as n = 1.
