Typical growth curves of the diploid S288C-derived laboratory yeast strain GSY157 (A), the industrial fuel ethanol CAT-1 strain (B), as well as the diploid laboratory ura3/ura3 yeast strain FY1679 transformed with a multi-copy 2μ URA3+ control (no-insert) plasmid (C), or with the same plasmid containing a cloned SNO/SNZ gene pair from strain S288C (pBD1001) (D), in synthetic defined media (see Methods) containing 200 g/L glucose and lacking both pyridoxine and thiamin (green), or the same media supplemented with 1 mg/L of thiamin (blue).
