Zusammenfassung:The present invention provides a pretreatment method which enables the promotion of the enzymatic glycosylation of lignocellulose under relatively mild conditions by using a tree bark as a raw material with less energy. Specifically the present invention provides a step for producing a sugar from a tree bark, which is characterized by having the following steps: an alkali treatment step of immersing the tree bark in an alkali compound solution; a refining treatment step of refining the alkali treated tree bark mechanically into fine pieces; and an enzymatic glycosylation step of glycosylating the refined tree bark with an enzyme. The present invention also provides a method of producing an ethanol.
