The present invention provides a method for providing a target chemical, comprising: providing a cellulose-derived slurry comprising fermentable saccharides in one or several containers;subjecting cellulose-derived slurry from said one or several containers to separation to provide a liquid fraction comprising part of said fermentable saccharides from said cellulose-derived slurry and a suspended solids fraction, which is returned to said container; transferring said liquid fraction to a fermentor; fermenting fermentable saccharides ofsaid liquid fraction in said fermentor to provide a fermented liquid comprising said target chemical; and returning said fermented liquid to said one or several containers.
La présente invention porte sur un procédé pour l'obtention d'un produit chimique cible, comprenant : l'obtention d'une suspension épaisse issue de cellulose comprenant des saccharides fermentescibles dans un ou plusieurs récipients ; le fait de soumettre la suspension épaisse issue de cellulose provenant dudit ou desdits récipients à une séparation pour fournir une fraction liquide comprenant une partie desdits saccharides fermentescibles provenant de ladite suspension épaisse issue de cellulose et une fraction de matières solides en suspension, laquelle est renvoyée vers ledit récipient ; le transfert de ladite fraction liquide vers un fermenteur ; la fermentation des saccharides fermentescibles de ladite fraction liquide dans ledit fermenteur pour fournir un liquide fermenté comprenant ledit produit chimique cible ; et le renvoi dudit liquide fermenté vers ledit ou lesdits récipients.
