The effect of chitosan on the crystallinity of the BC-chitosan composite from biosynthesis was not clearly observed because only a low concentration of chitosan [0-0.75% w/v] was added into the culture. At chitosan concentrations greater than 0.75% w/v, the production of cellulose was significantly affected [19].

Recently, Lin et al. [73] successfully produced microbial cellulose and microbial cellulose/chitosan membranes in large scale. The composite was prepared by immersing microbial cellulose in chitosan solution followed by freeze-drying. The incorporation of chitosan in microbial cellulose (i.e., microbial cellulose/chitosan) led to a more compact fibril network with smaller pore size than microbial cellulose. The swelling behavior, water retention capacity, moisture content, permeability and mechanical properties...
