| Abstract: | Objective: To control the characteristic of Gluconbacter melanogenus in medium with high concentration of D-sordibol(38%). Method: by changing seed liquid and using semi-continuous fermentation.Result: The strain could be cultured well in medium containing D-sorbitol in 38 % . The conversion rate of D-sorbitol to L-sorbose in medium with 38 % D-sorbitol was 95 % over 30 hours. There was no notably different about the yields of L-sorbose in 5 generations fermentations continuously. Conclusion: The productivity of sorbose was improved notably. |
| Keywords: | fermentation sorbitol L-sorbose seed liquid |
