Growth protocol
Strain and Growth Conditions Wild-type S. cerevisiae strain CEN.PK113-7D (MATa) (1) was grown at 30 °C in 2-liter chemostats (Applikon), with a working volume of 1.0 liter as described in Ref. 2. Cultures were fed with a defined mineral medium that limited growth by glucose, ethanol, acetate, or maltose with all other growth requirements in excess. The dilution rate was set at 0.10 h-1. The pH was measured on-line and kept constant at 5.0 by the automatic addition of 2 M KOH with the use of an Applikon ADI 1030 biocontroller. Stirrer speed was 800 rpm, and the airflow was 0.5 liters_min-1. Dissolved oxygen tension was measured online with an Ingold model 34-100-3002 probe, and was between 60 and 75% of air saturation. The off-gas was cooled by a condenser connected to a cryostat set at 2 °C and analyzed as previously described (3). Steady-state samples were taken after 10-14 volume changes to avoid strain adaptation caused by long term cu ltivation (4). Media The defined mineral medium composition was based on that described by Verduyn et al. (5). The carbon source was 256 mmol of carbon/liter. 1. Pronk, J. T., Wenzel, T. J., Luttik, M. A.
