<p>A fermentation inhibitor, which serves as an obstacle in at least one of the following steps, that is, a step for producing a monosaccharide and/or an oligosaccharide of a pentose and/or a hexose using a polysaccharide-based biomass as a starting material, and a step for converting the monosaccharide and/or oligosaccharide thus obtained into a chemical via fermentation, is efficiently removed. A treatment for removing a fermentation inhibitor with the use of a separating membrane is performed in the step prior to the saccharification step and/or in the step prior to the fermentation step in at least one of the following steps, that is, a step for producing a monosaccharide and/or an oligosaccharide of a pentose and/or a hexose using a polysaccharide-based biomass as a starting material, and a step for converting the monosaccharide and/or oligosaccharide thus obtained into a chemical via fermentation.</p> |
