Title: (EN) Process for the recovery of a fermentation product
Abstract: front page image
(EN)

The present invention provides a process for the purification and concentration of a partially water-soluble organic product from a source containing the same at concentration C0, which process comprises the steps of: (i) concentrating said product by means of a resin to form a first aqueous solution at concentration of C1; and (ii) fractionating an aqueous solution by temperature adjustment to form a second aqueous solution and a third aqueous solution with concentrations C2 and C3, respectively, wherein C2>C3 and C2>C1>C0.
