Summary:It is disclosed a process forincreasing the enzymatic accessibility of a thermally treated ligno- cellulosic biomass feedstock which has been thermally treated at a severity factor. The process comprises a step of fiber shives reduction, for reducing the amount of long shives. The thermally treated ligno-cellulosic biomass after fiber shives reduction is characterized by having an increased glucans accessibility and by forming a slurry having a low viscosity. La présente invention concerne un procédé permettant d'augmenter l'accessibilité enzymatique d'une biomasse lignocellulosique thermiquement traitée, qui a été thermiquement traitée à un facteur de sévérité. Le procédé comprend une étape de réduction des bûchettes fibreuses, pour réduire la quantité des longues bûchettes. Après la réduction des bûchettes fibreuses, la biomasse lignocellulosique thermiquement traitée est caractérisée en ce qu'elle présente une accessibilité accrue aux glucanes et en ce qu'elle forme une bouillie peu visqueuse.
