From: Scaling-up Fermentation of Pichia pastoris to demonstration-scale using new methanol-feeding strategy and increased air pressure instead of pure oxygen supplement

Figure 1

Time-course profiles of the HCDF under the two different conditions: Ip-Air (filled diamond) and Np-Ox (filled cycle).

(a) Cell density profiles (DCW, g/L). (b) Volumetric enzyme activity profiles (U/L). (c) Biomass enzyme activity profiles (U/g). Data are means ± SD of three parallel measurements (*P < 0.05, **P < 0.01, ***P < 0.001). Note, Ip-Air: increasing air pressure without pure oxygen supplement; Np-Ox: normal air pressure (0.05 MPa) with pure oxygen supplement (control).
