Abstract. Freeze-etching of never-dried pellicles or of incubated suspensions of both
Acetobacter xylinum and Acetobacter acetigenum show a nascent form of the cellulose
microfibril which has a core surrounded by an amorphous sheath. Drying of the pellicle
or suspension reduces the diameter of the sheath and changes the form of the microfibril
to the one usually seen. This nascent form of the cellulose microfibril is consistent with
previous postulations ofan intermediate polymer or polymers in the biosynthesis ofcellulose.
