Time-course profiles of the two different induction DO values.
(a) Cell density profiles (DCW, g/L). (b) Volumetric enzyme activity profiles (U/L). (c) Biomass enzyme activity profiles (U/g). Note, 1% DO (filled diamond); 5% DO (filled cycle). Data are means ± SD of three parallel measurements (*P < 0.05, **P < 0.01, ***P < 0.001).
