Production and characterization of bacterial cellulosewith komagataeibacter hansenii GA2016

Cellulose is the most common polymer in the world, formed by β-1,4 linked glucopyranose units. Cellulose that is produced by various microorganisms via biosynthesis is called bacterial cellulose (BC). In this study, the cellulose-producing bacteria was isolated from the homemade apple vinegar and identified as Komagataeibacter hansenii GA2016. BC was produced with the BC producer microorganism and the physical, chemical, structural and thermal properties of the produced BC were determined. It was found that Komagataeibacter hansenii GA2016 produced highly crystalline BC. The FTIR spectrum of the BC was similar to the plant cellulose spectrum, its fiber diameter was about 120 times thinner than plant cellulose and the thermal stability was higher than that of plant cellulose. As a result of this study, it has been shown that Komagataeibacter hansenii GA2016 produces BC with high yield and superior physicochemical properties compared to many polymers, and thus it can be used for the production of BC in food industry
