Aerobic growth of S. cerevisiae strains in YNB medium with 50 g/l arabinose as the sole carbon source. A. Laboratory strains BWY02.Xp (◆) (xylose pathway and empty multicopy plasmids) and BWY02.XA (■) (xylose and arabinose pathways). B. Industrial strains TMB 3400 (■) (xylose pathway), TMB 3061 (◆)(xylose and arabinose pathways), and TMB 3063 (▲) (xylose and arabinose pathways).
