摘要

Enzymatic after-treatment of biomass hydrolysate, which is obtained by the treatment with aqueous halogen hydracids, comprises: (a) admixing of hydrolytically active enzymes after the process steps of hydrolysis using aqueous halogen hydracids and separation of aqueous halogen hydracids by distillation; (b) carrying out a further process step between the separation of the aqueous halogen hydracids and the treatment with enzymes, and the enzymes hydrolyze non hydrolyzed residual charges.
