Abstract
A process for producing a saccharified solution, by which xylose can be produced at a high yield from lignocellulosic biomass, is provided. The saccharification is carried out by adding a saccharifying enzyme to a pretreated material for saccharification of the lignocellulosic biomass. As the saccharifying enzyme is added a mixture of a first saccharifying enzyme originated from one or more microorganisms selected from the group consisting of fungi of the genus Acremonium, the genus Trichoderma, the genus Penicillium, the genus Aspergillus and the genus Thermoascus, and eubacteria of the genus Clostridium and the genus Bacillus, and a second saccharifying enzyme composed of β-xylosidase originated from Thermotoga maritima.
