Claim:
1. Fermentation process for the production of an organic acid salt comprising the steps of fermenting a carbohydrate source by means of a microorganism in a fermentation medium in a fermentation reactor to form a fermentation broth comprising an organic acid salt, wherein a first part of the organic acid salt is present in the solid state and a remaining part of the organic acid salt is dissolved in the fermentation broth; withdrawing at least part of the fermentation broth from the fermentation reactor, providing said withdrawn broth to a hydrocyclone, and withdrawing a top effluent and a bottom effluent from the hydrocyclone; providing the bottom effluent from the hydrocyclone to a solid/liquid separation step, to form a solid fraction and a liquid fraction, providing at least 30 vol. % of the total of (1) the top effluent from the hydrocyclone and (2) the liquid fraction from the solid-liquid separation step to the fermentation reactor.
