On the other hand, the macroscopic morphology of BC mainly depends on the cultivation method, being in a form of pellicle when it is produced in static conditions, or in the form of irregular granules, stellate, and fibrous strands when the culture is agitated in either shake culture or rotating disk system. In addition, microscopic images also revealed morphological differences between both culture systems. Nanofibrils produced under static conditions are more extended and piled above one another in a crossing manner, and have a larger cross-sectional width. The cellulose pellicle obtained in agitated culture consists of entangled and curved nanofibrils. These morphological differences contribute to varying crystallinity and other important properties of BC [17].
