| Strains | wild-type Saccharomyces cerevisiae CEN.PK 113-7D |
| Genotype | MATa ura3-52 MAL2-8cSUC2 |
| Culture medium | For batch cultivations, a previously described (Verduyn et al.1992)mineral salts mediumwasused,commonly called CBS,having the following composition (per liter): (NH4)2SO4, 5 g;KH2PO4, 3 g; MgSO4-7H2O, 0.50 g; Antifoam 289, 0.050 mL; trace metals,1 mL; and vitamins, 1 mL. The trace metal solution consisted of the following (per liter): EDTA (sodium salt), 15.0 g;ZnSO4-7H2O, 0.45 g; MnCl2-2H2O, 1 g; CoCl2-6H2O,0.3 g; CuSO4-5H2O, 0.3 g; Na2MoO4-2H2O, 0.4 g;CaCl2-2H2O, 0.45 g; FeSO4-7H2O, 0.3 g; H3BO3, 0.1 g; and KI, 0.1 g. The pH of the trace metal solution was adjusted to4.0 with 2 M NaOH prior to heat sterilization. The vitamin solution contained (per liter): biotin, 0.05 g; p-amino benzoic acid, 0.2 g; nicotinic acid, 1 g; Ca pantothenate, 1 g; pyridoxine HCl, 1 g; thiamine HCl, 1 g; and myo-inositol, 25 g. The pH of the vitamin solution was adjusted to 6.5 with 2 M NaOH. The vitamin solution was filter sterilized and stored at4 C.This medium was supplemented with 20g/Lglucose. |
