Fig. 2.

Thermotolerance of 124 S. cerevisiae strains including two parent strains ScY01 and W65. a Cell growth (black bar), consumed glucose (red bar) and produced ethanol (blue bar) at 42 °C for 36 h. Cells were grown in YP medium containing 200 g/l glucose. b Cell growth of two parent strains ScY01 and W65 at 42 °C and 30 °C. Cells were grown in 100 ml Erlenmeyer flasks containing 50 ml YP medium with 200 g/l glucose. Data represent the mean and standard error of duplicate cultures at each condition (error bars are covered by symbols). Initial OD₆₀₀ of 0.5 was used for all the fermentations. In panel b, data represent the mean and standard error of duplicate cultures at each condition
