USE OF CO2 FOR DEACTIVATING A CELLULOLYTIC MICROORGANISM USED IN THE BIOCHEMICAL CONVERSION OF LIGNOCELLULOSIC MATERIALS

摘要

The invention concerns a process for deactivating a cellulolytic microorganism enabling the production of an enzymatic cocktail, said cocktail being used without separating the cellulolytic microorganism during the biochemical conversion of lignocellulosic materials, comprising at least one step for bringing a gaseous stream into contact with a medium containing said microorganism, said gaseous stream comprising more than 25% by weight of CO2 and comprising less than 0.5 molar % of O2.
