Methods for obtaining concentrated sugar solution from polysaccharide enriched biomass by contacting biomass with water and at least one nucleophilic base to produce a polysaccharide enriched biomass comprising a solid fraction and a liquid fraction and then contacting the solid fraction with saccharification enzyme consortium to produce a saccharification product comprising at least about 7 percent by weight sugars in 24 hours. The methods include optionally adding at least one additive selected from the group consisting of polyethylene glycols, fatty acid esters, fatty acid ethoxylates, nonionic surfactants derived from polyethoxylated sorbitan and a fatty acid, sodium lauriminodipropionate, sodium cocoamphoacetate, sodium tridecyl ether sulfate and a combination of these, such that enzyme loading of the saccharification enzyme consortium can be reduced.

L'invention porte sur des procédés pour obtenir une solution de sucre concentrée à partir d'une biomasse enrichie en polysaccharide par la mise en contact d'une biomasse avec de l'eau et au moins une base nucléophile pour produire une biomasse enrichie en polysaccharide comprenant une fraction solide et une fraction liquide puis la mise en contact de la fraction solide avec un consortium d'enzymes de saccharification pour produire un produit de saccharification comprenant au moins environ 7 pour cent en poids de sucre en 24 heures. Les procédés comprennent facultativement l'ajout d'au moins un élément supplémentaire choisi dans le groupe constitué par les polyéthylènes glycols, les esters d'acide gras, les éthoxylates d'acide gras, les agents tensioactifs non ioniques dérivés du sorbitan polyéthoxylé et d'un acide gras, le lauriminodipropionate de sodium, le cocoamphoacétate de sodium, le sulfate d'éther tridécylique de sodium et une combinaison de ceux-ci, de telle sorte que la charge enzymatique du consortium d'enzymes de saccharification peut être réduite.
