Abstract: By filtering, through an ultrafiltration membrane of a 600-2000 fraction molecular weight, an aqueous sugar solution obtained by hydrolyzing a cellulose-containing biomass, removing fermentation inhibitors on the permeated side and recovering the sugar solution from the un-permeated side, this method is capable of manufacturing a sugar solution with an extremely low amount of fermentation inhibitors.

Abstract: The present invention improves the filterability in a solid-liquid separation of a saccharified solution using a microfiltration membrane, by adjusting a lignin content of a pretreatment substance derived from a cellulose-containing biomass to 8.5% or lower whereby a cake, in which a solid content in the saccharified solution is concentrated on a membrane surface, is more likely to be formed. In addition, the present invention enables an efficient solid-liquid separation of the saccharified solution using the microfiltration membrane by collecting the cake formed on the membrane surface.

Abstract: In a process of producing a sugar liquid from a woody biomass, the conventional techniques have such a problem that a specific component contained in the sugar liquid from the woody biomass remarkably deteriorates the filtration performance when the sugar liquid is filtrated through a microfiltration membrane and/or an ultrafiltration membrane. In the present invention, it becomes possible to improve the filtration performance of the sugar liquid through the microfiltration membrane and/or the ultrafiltration membrane, and it also becomes possible to produce the sugar liquid with high efficiency by hydrolyzing the woody biomass to produce a liquid component and then reacting the liquid component with a mannanase.

Abstract: The problem addressed by the present invention is manufacturing a sugar solution in which the amount of fermentation inhibiting substances is extremely low. The present invention is a method that concentrates an aqueous solution of sugar derived from cellulose using a nano filtering membrane and/or a reverse osmosis membrane and is a method for manufacturing a sugar solution in which an anionic polymer is added and fermentation inhibiting substances are eliminated on the permeated side of a nano filtration membrane and/or a reverse osmosis membrane.

Abstract: In solid-liquid separation of a saccharified liquid by filtration through a microfiltration membrane, the filtration performance can be increased by adjusting the lignin content in a pretreated product derived from a cellulose-containing biomass to not more than 8.5% to promote formation, on the membrane surface, of a cake in which the solid component in the saccharified liquid is concentrated. Collection of the cake formed on the membrane surface allows efficient solid-liquid separation of the saccharified liquid with the microfiltration membrane.
