Title
(DE) BIOREAKTOR
(EN) BIOREACTOR
(FR) BIOREACTEUR
Abstract
(EN)
A bioreactor for microbial conversion of at least one conversion substrate, which comprises a treatment zone to accommodate when in use a solution of said at least one conversion substrate, a culture holding zone to accommodate when in use a microbial culture capable of metabolising said at least one conversion substrate, a source of primary growth substrate for the microbial culture, a first permeable membrane forming an interface between the treatment zone and the culture holding zone, and a second permeable membrane forming an interface between the source of primary growth substrate and the culture holding zone, the first permeable membrane being of a material which will allow passage of the at least one conversion substrate from the treatment zone to the culture holding zone whilst being impermeable to the microbial culture, the second permeable membrane being of a material permeable to the primary growth substrate but substantially impermeable to water; and a process of operating said bioreactor.

(FR)
L'invention concerne un bioréacteur pour la conversion microbienne d'au moins un substrat de conversion, qui comprend une zone de traitement recevant, à l'utilisation, une solution du ou des substrats de conversion, une zone de maintien de culture recevant, à l'utilisation, une culture microbienne capable de métaboliser le ou les substrats de conversion, une source de substrat de croissance primaire pour la culture microbienne, une première membrane perméable formant une interface entre la zone de traitement et la zone de maintien de culture, et une seconde membrane perméable formant une interface entre la source de substrat de croissance primaire et la zone de maintien de culture, sachant que la première membrane perméable est en matériau qui laisse passer le ou les substrats de conversion depuis la zone de traitement vers la zone de maintien de culture et qui est imperméable à la culture microbienne, et sachant par ailleurs que la seconde membrane perméable est en matériau perméable au substrat de croissance primaire mais sensiblement imperméable à l'eau. L'invention concerne un procédé relatif au fonctionnement de ce bioréacteur.
