A biotechnological process for conversion of a raw material (100, 200) to a desired product (130, 230) by means of one or more biological or biochemical agents (102, 104, 202) such as microorganisms and/or enzymes characterised in that the amount of one or more of said biological or biochemical agents (102, 104, 202) is controllable by a process control algorithm (124,224) dependent on one or more values of interest related to a process stream. A specific aspect of the invention is the use of a process control algorithm for controlling enzyme addition in biofuel production by fermentation of biomass to alcohols.

La présente invention concerne un procédé biotechnologique de conversion d'un matériau brut (100, 200) en un produit souhaité (130, 230) au moyen d'un ou plusieurs agents biologiques ou biochimiques (102, 104, 202) tels que des microorganismes et/ou des enzymes caractérisés en ce que la quantité dun ou plusieurs desdits agents biologiques ou biochimiques (102, 104, 202) soit contrôlable par un algorithme de contrôle de procédé (124, 224) dépendant d'une ou de plusieurs valeurs intéressantes liées à un courant du procédé. Un aspect spécifique de l'invention est l'utilisation d'un algorithme de contrôle de procédé pour contrôler l'addition d'enzymes dans la production de biocarburants par la fermentation de la biomasse en alcools.
