Methods And Compositions For The Treatment Of Cellulosic Biomass And Products Produced Thereby

Patent No. EP3280812 (titled "Methods And Compositions For The Treatment Of Cellulosic Biomass And Products Produced Thereby") was filed by Comet Biorefining on Apr 8, 2016. The application was issued on Feb 28, 2024.

Patent Summary

Methods for treating cellulosic biomass to produce cellulosic sugars, including activating cellulosic feedstock and enzymatic hydrolysis to produce glucose. The methods involve a two-step activation process that increases the level of glucan and decreases the level of lignin in the feedstock, followed by enzymatic hydrolysis using a cellulase enzyme mix. The glucose-rich sugar stream produced by this process contains a unique composition of non-glucose sugars, including xylose, xylo-oligosaccharides, and xylan, which provides a lower glycemic index compared to traditional glucose products.
