- Аннотация: This research is dedicated to the studies of the microscale morphology of bacterial cellulose (BC) obtained bymeans of static cultivation of Gluconacetobacter hansenii GH-1/2008. We found that the microscale morphology depended on the BC production rate that was varied by using different glucose concentrations in the cultivation medium. It was revealed that at higher production rates, BC fibrils were aligned in a liquid-crystalline-like (LC-like) order. The observed helical alignment was always left-handed. The half-periods of the helix varied from 50 μm to 150 μm depending on the cultivation conditions. The mechanical and water absorption properties of the obtained BC pellicles were measured. The former correlated mainly with the density of the samples; the latterwere the best for films with layered structure, where the BC had segregated into fleece sheets separated by gaps with low density of fibrils.
