We investigated the optimal condition for production of bacterial cellulose with Gluconacetobacter persimmonus KJ145. For bacterial cellulose production, optimal medium composition and culture conditions were conducted to determine. Apple juice (10$^{\circ}$Brix) medium was suitable than Hestrin & Schramm medium which is generally used for the bacterial cellulose production. When 1% pyruvate as carbon source was added to apple juice, bacterial cellulose production rose to high level. The effect of various nitrogen sources was investigated: CSL was found to be essential to high cellulose yields and the optimal CSL concentration was 10%. Optimal temperature and culture time for the bacterial cellulose production was 35$^{\circ}C$ and 16 days, respectively At the optimal condition Gluconacetobacter persimmonus KJ145 produced 8.96g/L of bacterial cellulose (dry weight), which was much higher than reported values.
