<p>Disclosed is a plant biomass pretreatment method which can achieve a pretreatment of a plant biomass rapidly in a simple facility. A pretreatment of a plant biomass is carried out in an extruder, wherein the pretreatment comprises steps of coarsely milling the plant biomass in pieces each having a predetermined size or smaller, adding a degrading agent to the coarsely milled plant biomass, treating the plant biomass to which the degrading agent has been added with hot water under pressure, and carrying out the saccharification rest by mixing the plant biomass which has been treated with hot water under pressure with an enzyme for saccharifying the plant biomass, and wherein the steps are carried out in this order continuously.</p> |
