AB  - Bacterial cellulose (BC) has shown potential as a separation material. Herein, 
      the performance of BC in pressure-driven separation is investigated as a function 
      of incubation conditions and post-culture treatment. The pure water flux of 
      never-dried BC (NDBC), was found to be 9 to 16 times higher than that for dried 
      BC (DBC), in a pressure range of 0.25 to 2.5 bar. The difference in pressure 
      response of NDBC and DBC was observed both in cross-flow filtration and capillary 
      flow porometry experiments. DBC and NDBC were permeable to polymers with a 
      hydrodynamic radius of  approximately 60 nm while protein retention was possible by introducing 
      anionic surface charges on BC. The results of this work are expected to expand 
      the development of BC-based filtration membranes, for instance towards the 
      processing of biological fluids.
