Physico-chemico mechanical characteristics of bacterial cellulose produced in fed batch cultivation using waste from beer fermentation broth |
| 초록 |
BC membranes were produced by G. hansenii PJK in jar fermenters using the waste from beer fermentation broth (WBFB) in fed-batch cultivation. The structure and some properties of BC membrane were investigated. FE-SEM revealed that the reticulated structure of BC fibrils was almost same to the control system (chemically defined medium). The FTIR spectral range, and chemical shifts from CP/MAS (13C-NMR) study were also same to the control system. Nevertheless, BC produced using WBFB exhibited micro-structural changes, namely, a low degree of polymerization and low crystal size compared to control system. CP/MAS 13C NMR analysis revealed that the cellulose Iα and Iβ content of the cellulose produced using WBCB was almost same to the control sytem. The BC produced using WBFB had a lower Young's modulus of sheet, a higher water holding capacity as compared to the control system. |
