| Abstract: | complex
medium was developed for the production of microbial cellulose by Acetobacter xylinum. The
optimum concentration of each nutrient for the production of microbial cellulose was determined
to be peptone 1%, yeast extract 0.5%, glucose 2%, Na 2HPO 4 1%, citric acid 0.115%, ethanol
1%. The maximal yield of cellulose productionis 7.55g/l at shaking speed 160 r/min, pH6.0. Cell
growth and the cellulose production in the developed medium under shakingflask culture was
also investigated. |

| Keywords: | Acetobacter xylinum bacterial cellulose maximal yield shaking-flask culture |
