| titleOfInvention | Method for producing L-alanine by feeding fermentation |
| abstract | The invention relates to a method for producing L-alanine by fed-batch fermentation, which is characterized in that in the process of culturing a mutant strain Lds.0108 of lactobacillus delbrueckii by using a glucose culture medium with the glucose concentration of 95-105g/L, when the residual sugar content in fermentation liquor is lower than 45g/L, a glucose solution with the concentration of 50-75% is fed into the fermentation liquor at one time until the total concentration of glucose added into the fermentation liquor is 125-170 g/L, and the fermentation is continued until the fermentation is finished. The method improves the yield of the L-alanine by supplementing the glucose solution on the basis of the basic fermentation medium, is simple and easy to implement, has obvious effect, improves the concentration of the L-alanine in the fermentation tank from 80-100g/L to 120g/L of 110-90 percent, and has the fermentation conversion rate of more than 90 percent. |
