Abstract

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.
