Abstract
A process of covalently modifying a lignocellulosic material is provided. The process includes oxidizing a lignocellulosic material having hydroxyl groups with an oxidant to oxidize at least a portion of the hydroxyl groups to carboxylic acid groups, optionally activating the carboxylic acid groups with an activating agent to form activated carboxylic acid groups, and reacting the carboxylic acid groups or the activated carboxylic acid groups with a first nitrogen-containing reagent selected from amino acids, peptides, or protected derivatives thereof to provide a treated lignocellulosic material. The treated lignocellulosic materials thus prepared displays resistance to degradation.
