Culture conditions for the production of Cellulose I and/or II structures have been investigated by transmission electron
microscopy using smooth colonies of Acetobacter xylinum ATCC23769. Cells prepared from smooth colonies produce the band material composed of Cellulose II in phosphate buffer (pH
7) at 4 °C. In contrast, the same cells produce the normal twisting ribbons of Cellulose I when the incubation temperature
is raised to 28 °C. The band material is also produced at 4 °C in 2% buffered glucose solution and in the standard Hestrin-Schramm
medium.

The supramolecular architecture and the morphological structure of cellulose play an important role in its accessibility.
In order to evaluate the effect of the crystalline form of organization on the accessibility, we selected cellulosic materials
with significant variations in the aforementioned characteristics. The assessment of the accessibility of cellulosic materials
was performed experimentally through a water vapor sorption method. The kinetics and the thermodynamic parameters of water
vapor sorption process were determined, and a correlation between the Flory–Huggins interaction parameters and the crystallinity
index was derived. We concluded that the allomorph involving the most accessible crystal surfaces and amorphous regions was
Cellulose II. The correlation of the accessibility values with those of the crystallinity index allowed us to evaluate the
accessibility of the allomorphic forms of cellulose at different crystallinity indexes. The obtained experimental data allowed
us to quantify the accessibility for crystal surfaces and amorphous regions of the different allomorphs in the order Cellulose
II (38%) > Cellulose I (24%) > Cellulose III (10%). 相似文献

A series of Cellulose/poly-ethylene imine (PEI) composites were prepared by grafting hyperbranched PEI onto cellulose chains in alkali/urea aqueous solvent system through “one step” method. The SEM results showed that the Cellulose/PEI composite maintained porous structure. The Cellulose/PEI composites were tested as Cu(II) adsorbents through thermodynamics and kinetics study. The adsorption process followed pseudo-second-order kinetics equation. The adsorption isotherms could be described by both Langmuir and Freundlich isotherm models. The maximum adsorption amount was calculated to be 285.7 mg/g. The composites showed good stability so that they could be used in a wide range of pH and temperature. Besides, the Cu(II) loaded Cellulose/PEI composite could also be easily regenerated by dilute sulfuric acid and still keep a major adsorption capacity. Finally, the adsorption capacities of Celluloes/PEI composite towards other metal ions, such as Zn(II), Ni(II), Cr(III) and Pb(II), were also demonstrated. It will be a new high-performance and environmental friendly material for sewage disposal and metal pollution treatment with promising developmental potential. 相似文献
