Abstract
Procédé rapide de fermentation de la cellulose. Il consiste à fournir un matériau cellulosique particulaire ou fibreux dans lequel au moins une quantité importante de la cellulose est accessible, à mélanger un milieu minéral nutritionnel aqueux à ce matériau cellulosique particulaire pour former une suspension ayant un pH compris entre 7 et 8, ce milieu minéral nutritionnel aqueux étant une source d'éléments nutritifs pour la culture mixte, à mélanger cette culture mixte avec cette suspension, à faire fermenter le mélange résultant à une température comprise entre 50 et 65 degrés C environ et à un pH de 7 à 8 environ pour produire au moins une quantité significative d'éthanol et à récupérer cet éthanoL Application à la fabrication de l'éthanol.
