This work aims to simulate a bioreactor to produce ethanol from glucose using immobilized cells . First, we have proceeded to statistically evaluate the proposed kinetic models , from which we selected the model Aiba , Shoda and Nagathani [18 ] as the most appropriate model . Second, the values ​​of the simulated fermentation have been validated by comparing the results with experimental data and Mutharasan Gencer [17 ] . Finally , the yield of ethanol production was simulated by considering a bioreactor of PFR type . The solution of the equations of material balance was done using Runge Kutta algorithm in Mathcad 7P IV . Comparison of simulated and experimental Mutharasan Gencer sample values ​​appropriate arrangement .

We can say that the science and engineering of materials as such, arises in the heat of the big projects Aerospace and Defense, which has had as contenders to the United States and the former USSR in the years of the Cold War. However, we know that historically the discovery and use of materials by man, has drawn almost inexorably the course of their own development. No wonder, therefore, that this science is largely responsible for the great technological advances that humanity is experiencing at the present time.

Podemos decir que la ciencia e ingeniería de materiales como tal, surge al calor de los grandes proyectos Aerospaciales y de Defensa,que ha tenido como contendientes a los Estados Unidos de Norteamérica y la ex URSS en los años de la guerra fría. Sin embargo, sabemos que históricamente el descubrimiento y uso de los materiales por el hombre, ha trazado casi de manera inexorable el rumbo de su propio desarrollo. No es extraño por tanto que esta ciencia, sea en gran medida, la responsable de los grandes avances tecnológicos que experimenta la humanidad en los tiempos actuales.
