  • A process for the production of mannitol from fructose (5% to 25%) using Leuconosyoc mesenteroides NRRL B-1149 was investigated. Fermentations were carried out in bat도 of fed-batch fermentations without aeration at 28℃, pH 5.0. When 5% fructose was used in batch culture fermentation, the yield of mannitol was 78% of that expected theoretically. When the fructose concentration was increased to 10%, the yield dropped to 59.6% of the theoretical value. However, in the fed-batch culture, using 10% fructose, the yield was 81.9% of the theoretical value. In a 15% fructose fed-bat도 culture, with 5% fructose being added initially and the other 10% fructose being added as a continuous supply, the final yield was 83.7% of the theoretical yield. When 20% fructose was used in the same manner, the yield was 89.5% of theoretical yield.
