Procedure

A 10% sodium lactate solution was reacted at 30° C. according to the invention with a saturated solution of CO2 in water (carbonic acid). 46 g Sodium lactate produced 36 g of lactic acid and 20 g of sodium carbonate which may be used as a solution for neutralizing and regulating the pH of a fermentation. A further purification of the lactic acid can be performed by known methods using ion exchangers, esterification or extraction.
