Method for preparing pure lactic acid |
| abstract |
The invention relates to a method for preparing pure lactic acid or a salt thereof by fermentation. The preparation process comprises bioreactor refreshing cycle and a lactic acid production cycle, wherein during the production cycle a solution comprising substantially pure feedstock is recycled through a bioreactor containing refreshed microorganism cells, the lactic acid produced being neutralized by adding an alkali, and the recycling is discontinued when the alkali consumption is substantially diminished, and during the refreshing cycle the microorganism cells are refreshed by recycling through the bioreactor a carbohydrate solution enriched with nutrients, thus replenishing the capacity of the microorganisms to produce an acid, and recovery of lactate or conversion thereof into lactic acid or other salt. |
