Abstract

González y M. Gutiérrez-Rojas In this work the dynamics of a sulfate reducing bacteria is predicted by estimating the biomass concentration and sulfide 259 Crecimiento, sobrevivencia y adaptación concentration measurements. The estimation process is developed production using only sulfate (substrate) de Bifidobacterium infantis a condiciones ácidas on batch, fed-batch andcontinuous cultures of Desulfovibrio alaskensis 6SR, where a mathematical dynamic model (Growth, survival and adaptation of Bifidobacterium infantis to acidic conditions) of the bioreactor is presented and tuned with experimental data. The design of the adaptive smooth state observer takes into L. Mayorga-Reyes, P. Bustamante-Camilo, A. an adaptive gain of the output feedbackAzaola- contain a accountthe model’s system structure and Gutiérrez-Nava, E. Barranco-Florido y A. which hyperbolic Espinosa of the estimation error, an theoretical frame is provide in order to show the convergence tangent characteristics of the proposed method. The results of the proposed estimation methodology are generated via 265 Statistical approach to optimization of ethanol fermentation by Saccharomyces cerevisiaein the numerical simulation in order to show its performance.
