| titleOfInvention | Fermentation method of citric acid |
| abstract | The invention discloses a fermentation method of citric acid, comprising the following step of: under a fermentation condition, inoculating citric acid fermentation strains into a citric acid fermentation culture medium, wherein fermentation is performed continuously at multiple stages including a first fermentation stage and a fermentation stage after the first fermentation stage; in the first fermentation stage, feeding a citric acid fermentation culture medium and a fermentation strain seed liquid into a fermentation tank, the feeding amount of the citric acid fermentation culture medium and the feeding amount of the fermentation strain seed liquid enable the acidity of citric acid in the fermentation liquid in the stage to be 50-100g/L and the concentration of reducing sugar to be 60-100g/L; and the fermentation liquid in the first fermentation stage flows into the fermentation tank of the next stage sequentially and continuously for fermentation, the acidity of citric acid in thefermentation liquid at the fermentation end-point is not less than 140g/L, and the content of residual reducing sugar is 0-4g/L. The fermentation method of citric acid provided by the invention can improve the utilization efficiency of fermentation equipment, shorten the production cycle and achieve the aim of lowering the citric acid fermentation cost. |
