Notes:
The temperature-profile curve of ethanol production of the yeast Saccharomyces cerevisiae Sc 5 is shown. Accordingly the biokinetic sphere of ethanol formation consists of 5 ranges. The maximum specific ethanol formation rate v0 is reached within the temperature limits of 32°C ≦ T ≦ 36°C, and the maximum temperature for ethanol formation amounts to T″max = 57°C. Within the first suboptimum temperature range ethanol formation is not retarded thermally. Using a modified ARRHENIUS equation the activation energy of ethanol formation was calculated to be ΔHÊtOH = (78.5 ± 2.2) kJ/mol.
