Abstract: The present invention relates to a method for preparing bioethanol from lignocellulosic biomass. The method of the present invention is capable of: minimizing the impurity content of an enzymatic saccharification raw material, by extracting biomass using hot water, before pretreatment, and removing extractable substances such as inorganic salts; suppressing, to the greatest extent, the production of overdecomposition products of sugar, by pretreating the biomass, from which the hot water extractable substances have been removed, in a condition for maximizing xylan yield; preparing fermentable sugar at a low cost, without washing a pretreated solid obtained from subsequent solid-liquid separation, but by only concentrating a sugar solution obtained after enzymatic saccharification, using a separation film; and preparing bioethanol therefrom in high yield.

Abstract: The present invention relates to a method for effectively recovering a sugar solution containing glucose and saccharogenic residues after saccharification using an acid or a saccharification enzyme of a wood-based or algae biomass, and a device for implementing the method. More specifically, the present invention relates to a method capable of recovering a sugar solution using minimal equipment and water after aggregating fine particles by adding a protein suspension to a suspension of glucose and saccharogenic residues which are produced by saccharifying cellulose by adding an acid or saccharification enzyme to the biomass, while capable of minimizing an amount of saccharide lost in the residues, and a device for implementing the method.

Abstract: The present invention relates to a method for preparing, from wood-based biomass, a high concentration of fermentable sugar which can be effectively used in culturing various industrial fermented bacteria. According to the method of the present invention, biomass can be extracted by hot water prior to a pre-treatment so as to remove extractible substances such as mineral salts to thus minimize the content of impurities in raw materials for an enzymatic saccharification. The biomass from which substances extractible by hot water are removed is pre-treated in the condition where xylan yield rate is maximized, thus achieving maximum inhibition of the generation of over-decomposed products of sugar.
