The Impact of the Mechanical Modification of Bacterial Cellulose Films on Selected Quality Parameters

This study investigated the effect of the homogenization of bacterial cellulose particles and their reintegration into a membrane on the mechanical and physical parameters of the films produced from them in relation to films made of native cellulose (not subjected to the homogenization process).
