The procedures to design fuel ethanol production processes with an enhanced
performance according to technoeconomic and environmental criteria require
the development and utilization of an appropriate, sufficient, and accurate
description of ethanolic fermentations. In particular, process analysis involves
the employment of simulation tools to assess the performance of such cultivation
processes, but the quality of simulation strongly depends on the quality
of mathematical models describing the fermentation. Thus, the selection of
already developed models, their modification, or the development of new ones
has become a crucial aspect of the methodologies for the design of bioethanol
production processes.
