METHOD FOR EFFICIENT ENZYMATIC HYDROLYSIS OF LIGNOCELLULOSIC MATERIALS

摘要

The invention relates to a method for efficient enzymatic hydrolysis of lignocellulosic materials and more particularly, it relates to efficient enzymatic hydrolysis of cellulosic part of lignocellulosic materials like corncob, corn stover, sugarcane/beet bagasse or any similar lignocellulosic materials.

主权项

1. A improved process for enzymatic hydrolysis of cellulosic biomass comprising:
(a) Providing a lignocellulosic material and preparing its mixture in water; (b) pretreating said mixture with one or more acids at a desired temperature for a desired time period to obtain a first stream; (c) adjusting pH of said first stream with a base to obtain a second stream; (d) treating said second stream with sodium sulphite at a desired temperature for a desired time period to obtain a third stream; (e) contacting said third stream with one or more of cellulolytic enzymes at desired temperature for a desired time period to obtain a sugar rich final stream; and (f) subjecting said final stream to a fermenting yeast to obtain ethanol.
