Growth Condition | |
Strains | Pichia pastoris X-33 |
Genotype | harbouring pGAPA delta as mock plasmid |
Culture medium | Two duplicate aerobic, carbon-limited continuous cultures for each of the three strains were carried out in a 3 L vessel bioreactor (Applikon Biotechnology) that was controlled at 25 Celsius . The working volume was kept at 1 L by means of an overflow system. The pH was controlled at 5.0 with 1 M NH3. P. pastoris cells were fed with a minimal medium containing 50 g/L of a glucose:methanol mixture (80% glucose/20% methanol, w/w) for five bioreactor volume changes until reaching a metabolic steady state, as indicated by a constant cell density in the bioreactor and constant O2 and CO2 concentrations in the exhaust gas. |
Carbon source | Glucose. |

Case-specific description | Metabolic flux distributions in the P.pastoris during growth in glucose and glucose:methanol chemostat cultures at about 0.1/h. |
