Abstract
TREJOS, VÍCTOR MANUEL; FONTALVO ALZATE, JAVIER and GOMEZ GARCIA, MIGUEL ÁNGEL. MATHEMATICAL DESCRIPTION AND STABILITY ANALYSIS OF FERMENTATIVE PROCESSES. Dyna rev.fac.nac.minas [online]. 2009, vol.76, n.158, pp.111-121. ISSN 0012-7353.
The advances in the fermentative processes as source of ethanol fuel leads to outline theoretical studies for the detailed understanding of that process. In this paper, the ethanol production in a continuous system with yeast cells is evaluated. The behavior of Monod and Haldane models for microbial growth is analyzed for a CSTR (Continuous Stirred Tank Reactor). The stability of the system, the dynamic behavior, the characterization of fixed points, phase planes and bifurcation points for each one of the two models of microbial growth are analyzed.
Keywords : Fixed points; dynamic behavior; bifurcation points.
