SIMULTANEOUS DELIGNIFICATION AND DEAGGREGATION OF BIOMASS

摘要

Disclosed are methods and systems for treating a lignocellulosic material or lignocellulosic containing biomass to delignifiy the material or biomass and make it more accessible for enzymatic or chemical modification. The system and methods include treating lignocellulose-containing material or biomass with an alkali in an exemplary alcohol/water co-solvent system. The treatment deaggregates the lignocellulosic material and at the same time delignifies the starting material or substrate. A liquid fraction contains a lignin composition having lignin is in a form closer to its native state than any known laboratory procedure is also provided.
