Abstract

The invention relates to a process for the preparation of a sugar and / or fermentation product from lignocellulosic material.

Description

technical field [0001] The present application relates to methods for the production of sugar products from lignocellulosic material by enzymatic hydrolysis and methods for the production of fermentation products by fermentation of sugars. Background technique [0002] Lignocellulosic materials are mainly composed of cellulose, hemicellulose, and lignin, and provide an attractive platform for generating alternative energy sources from fossil fuels. This material is available in large quantities and can be converted into valuable products such as sugar or biofuels such as bioethanol. [0003] The production of fermentation products from lignocellulosic materials is known in the art and generally includes the steps of pretreatment, hydrolysis, fermentation and optionally recovery of the fermentation products. [0004] During hydrolysis (which may include liquefaction, pre-saccharification and / or saccharification steps), the cellulose present in the lignocellulosic material is...
