Title (EN) METHOD FOR REDUCING THE VISCOSITY OF A NANOFIBRILLAR CELLULOSE HYDROGEL
(FR) PROCÉDÉ DE RÉDUCTION DE VISCOSITÉ D'HYDROGEL DE CELLULOSE NANOFIBRILLAIRE
Abstract: front page image
(EN)The invention relates to a method for reducing the viscosity of a nanofibrillar cellulose hydrogel, wherein the method comprises mixing a nanofibrillar cellulose hydrogel with an aqueous growth medium for cell culture, wherein the aqueous growth medium contains one or more salts and optionally one or more sugars, using shearing forces so that a homogeneous dispersion is formed. The invention further relates to a dispersion comprising a nanofibrillar cellulose hydrogel and an aqueous growth medium for cell culture and to a use of an aqueous growth medium.
(FR)L'invention concerne un procédé qui permet de réduire la viscosité d'un hydrogel de cellulose nanofibrillaire et qui consiste à mélanger un hydrogel de cellulose nanofibrillaire avec un milieu de croissance aqueux pour une culture cellulaire, le milieu de croissance aqueux contenant un ou plusieurs sels et éventuellement un ou plusieurs sucres, en utilisant des forces de cisaillement de telle sorte qu'une dispersion homogène est formée. L'invention concerne également une dispersion comportant un hydrogel de cellulose nanofibrillaire et un milieu de croissance aqueux pour une culture cellulaire, ainsi que l'utilisation d'un milieu de croissance aqueux.
