Bacterial cellulose (BC) white leathery pellicle produced from fermentation process of Acetobacter xylinum has many advantages such as high-water holding capacity, high porosity and high purity compared to plant cellulose. However, one of the BC application problems in industry is its low bio-cellulose productivity. The significant decrease of BC production can be effected by the reduction of pH culture due to production of by-product, gluconic acid during the static fermentation process. Therefore, the production of BC pellicle would be improved efficiently by controlling the pH of BC static cultivation. Bio-cellulose dry weight was at the greatest in acetates of 5.66 g/L while the dry weight derived from BC is 2.72 and 2.56 g/L in Control and Hestrin and Schramm (HS). The acetate buffered medium can be completed in a static fermentation method which can improve BC film production effectively. © Published under licence by IOP Publishing Ltd.
