Homogeneous and porous modified bacterial cellulose achieved by in situ modification with low amounts of carboxymethyl cellulose

摘要: To improve the rehydration ability of bacterial cellulose (BC), many macromolecules have been used as modifiers in previous reports. However, aggregation additives BC matrix appears to be inevitable. We investigated different parts a pellicle, which was achieved by situ modification with carboxymethyl (CMC) culture Gluconacetobacter xylinus ATCC53582 or Enterobacter sp. FY-07. observed concentration gradient CMC pellicle from G. ATCC53582, but not Low concentrations (0.01 %, m/v) are sufficient modify FY-07, could sufficiently contact newly formed BC. The crystallinity modified decreased more than 39.8 and its water holding capacity increased 43.3 31.0 respectively. Unlike obligate aerobes, such that produced FY-07 exhibited better homogeneity porosity.
