Aggregation of ribbons in bacterial cellulose induced by high pressure incubation

The nascent morphology of cellulose produced by Acetobacter aceti (AJ12868) incubated at 30 atmospheres pressures was investigated using AFM, TEM, X-ray and optical microscopy. The bacteria survived the elevated pressure and produced cellulose. The ribbons produced at 30atm had similar crystalline features as the ribbons produced in the control medium but exhibited larger microfibril aggregates.
