Determination of Stoichiometric Matrix for Ethanol Production from Xylose by Reduction of Elementary Modes with Ant Colony Systems

Résumé

Ethanol production is still based on an old technology with performance that requires innovative culture strategies to optimize productivity, ethanol concentration and conversion yield. Furthermore ethanol production of second generation requires using lignocellulosic materials (constituted by 35 to 45% of xylose). This paper addresses the problem of a determination of a stoichiometric matrix for ethanol production. A new method was proposed in order to simplify the set of elementary modes, an approach of optimization based on natural systems: Ant Colony Systems. The advantage of the presented method comes from the fact that it does not need to calculate distance between a node and a line and that only the knowledge of the coordinates of the elementary modes is necessary. This method was applied to xylose metabolism and a reducing stoichiometric matrix was obtained.
