Abstract

The present disclosure relates to a method for obtaining sugar and lignin fractions from lignocellulosic materials and to a method for producing fermentation products using the sugars obtained from the lignocellulose. The present disclosure relates to a method for improving the sugar yield in the enzymatic hydrolysate by introducing a pre-treatment step of hydrothermal hydrolysis and an alkaline delignification step.
