Abstract

In this paper, a novel enzymatic method was evaluated for isolation and purification of wood LIGNIN. The chemical structure of enzymatic LIGNIN (Cellulytic LIGNIN) was compared with conventional Bjorkman method (Milled wood LIGNIN). The chemical structure elucidation was performed with FTIR, quantative 13CNMR, basic elemental analysis and Gel Permeation Chromatography (GPC). The results showed that enzymatic LIGNIN preparation has a better chemical structure than MWL. Comparing to conventional isolation methods, application of an enzyme sequence with reduced milling time could lead to a mild EXTRACTION with less structural degradation of LIGNIN. Resulting LIGNIN could be more representative for wood LIGNIN than milled wood LIGNIN.
