Abstract: A fermentation process for producing magnesium lactate from a carbon source including the steps of: providing a fermentation medium including a fermentable carbon source in a fermentation reactor; fermenting the fermentation medium by a lactic acid producing microorganism in the presence of an alkaline magnesium salt to provide a fermentation broth including magnesium lactate; and recovering solid magnesium lactate from the magnesium lactate containing fermentation broth, wherein during at least 40% of the operating time of the fermentation process, the concentration of solid magnesium lactate in the fermentation broth is maintained in the range of 5-40 vol. %, calculated as solid magnesium lactate crystals on the total of the fermentation broth. The process allows stable operation at high productivity, in combination with efficient product separation.
