Method for Obtaining Products Containing Different Concentrations of Compounds Produced by Fermentation

A method for producing products which comprise at least one target substance produced by fermentation in a plurality of stages, in which

• a) fermenting microorganisms producing the desired target substance in a suitable medium and the target substance is accumulated therein,
• b) separating off the biomass formed during the fermentation completely,
• c) concentrating the solution or suspension of step (b) by removing the water, allowing the target substance to is precipitated out, in particular left to crystallize out,
• d) separating the precipitated-out or crystallized-out substance to form a mother liquor I,
• e) converting the target substance present in the mother liquor I to a desired product form,
• f) reducing the water content of the mother liquid I by evaporation and
• g) obtaining a further solid comprising the target substance.
