Abstract

Bacterial nanocellulose is a subject of extensive research due to its promising potential applications in medicine, veterinary and cosmetics. In this paper, effect of structural characteristics on enzymatic hydrolysis of bacterial nanocellulose (BNC) and microcrystalline cellulose (MCC) has been studied. Despite the similar degree of crystallinity and lateral size of crystallites for both cellulose samples, a conversion degree of BNC after enzymatic hydrolysis was considerably higher than of MCC. The main distinctive feature of the BNC sample is a high porosity and developed surface of nanofibrils. As against, the MCC sample contains coarse low-porous particles that have a poorly developed surface. Although drying reduces the porosity of the samples, the dry BNC retains a much higher pore volume and greater enzymatic hydrolysability than the dry MCC. Due to highly porosity and developed surface, the BNC sample acquires a high accessibility for molecules of cellulolytic enzymes that promotes enzymatic hydrolysis of this sample both in never-dried and dry state.
