Abstract

This study was carried out to investigate the effect of enzymatic hydrolysis on morphological characteristics of microfibrillated cellulose (MFC) with different lignin contents. Enzymatic hydrolysis using endoglucanase (EG) was successful to reduce the size of MFC. With increasing EG concentrations, the length and diameter of MFC were significantly decreased, even though it contained part of hemicellulose and lignin. Cellulose crystallinity was increased with increasing EG concentrations. With decreasing lignin content of MFC, dimension and cellulose crystallinity were more reduced and increased, respectively.
