Abstract: Disclosed is a process for recovery of amino acids from aqueous mixtures. In particular, it relates to a treatment of said amino acid containing aqueous mixture prior to extraction of the amino acid with a water immiscible organic solution containing a water insoluble extractant for said amino acid. The overall process of the invention which includes the pretreatment and extraction, also includes optional methods of recovering said extracted amino acid from the water immiscible organic solution. Accordingly, the invention also relates to a process for recovery of the amino acid by stripping of the amino acid from the organic solution and precipitation of the amino acid.

Abstract: The invention is a process for the separation of biotechnologically produced valuable materials from a fermenter broth by crossflow microfiltration and/or ultrafiltration, in which at least two modules arranged in series and fitted with porous membranes are used per stage, to produce concentrate and a permeate which contains the valuable material. The pressure of the permeate is controlled so that the absolute pressure on the permeate side is at different absolute pressure in each module.
