In a process for hydrolyzing plant material in aqueous solution or suspension with an enzyme, the enzyme is delivered in solid form (e.g., as a spray-dried powder) in closed containers (such as paper bags or cardboard boxes), which are added directly in the process (i.e. addition of whole boxes/bags). The invention is particularly amenable to the production of first or second-generation bioethanol. L'invention concerne un procédé d'hydrolyse d'un matériel végétal dans une solution ou une suspension aqueuse avec une enzyme, dans lequel l'enzyme est fournie sous forme solide (par exemple, sous forme d'une poudre séchée par atomisation) dans des récipients fermés (comme des sacs en papier ou des boîtes en carton), qui sont directement ajoutés dans le procédé (c'est-à-dire, addition des sacs/boîtes entiers). L'invention convient particulièrement à la production de bioéthanol de première ou de deuxième génération.
