Abstract
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.

A process for hydrolyzing a plant material, comprising:
- (a) preparing an aqueous solution or suspension of the plant material,
- (b) adding one or more container(s) which enclose(s) a multitude of particles comprising one or more enzyme(s) having hydrolytic activity towards the plant material so that the enzyme(s) is/are released to the solution or suspension, wherein the one or more containers filled with particles has a mass of at least 20 kg, and
- (c) incubating the solution or suspension so as to hydrolyze the plant material.
