| Summary: | 碩士 === 輔英科技大學 === 生物技術系碩士班 === 97 === Bacterial Cellulose (BC) is an extracellular beta-glucan produced by a species of Gluconacetobacter. This cellulose is different form that found in the cell walls of plants. Gluconacetobacter produce cellulose with special properties such as rigidity, strength, excellent biodegradability, high crystallinity, and large water holding capacity. Because of BC’s particular physical and chemical properties, there are many applications to numerous fields, such as biomedical materials and food products.Thus, researchers and industries are now searching for effective ways to produce BC by Gluconacetobacter.
When using traditional reactors, there are challenges to optimal bacterial growth such as high temperatures and shearing stress. For BC production,a airlift reactors has been used for cultivating Gluconacetobacter. Growing bacteria in the Airlift reactor allowed sphere formation, and showed an improvement in bacterial growth, metabolism, and cellulose yield. In this study, different cultivaion conditions have been investigated using the airlift reactors as well as net plates to produce BC.The water holding capacity ,loading force,tension and stress were examined.
