文摘

Ethanol fermentation by S. cerevisiae is conducted over a wide temperature range. A mechanistic kinetic model is developed to predict reaction rates. A methodology was proposed to estimate temperature-dependent kinetic parameters. The applicability of the kinetic model is validated for VHG ethanol fermentation. Conditions to produce ethanol with a higher yield and productivity are studied.
