Abstract: The present invention relates to a method for separating a molecule of interest from an antifoaming agent in a fermentation broth comprising said molecule of interest and said antifoaming agent. The method comprises the steps of filtering the fermentation broth at a temperature in the range of 1° C. to 15° C. above the cloud point of the antifoaming agent, and thereby obtaining a first fraction of the fermentation broth comprising the molecule of interest and a second fraction of the fermentation broth comprising the antifoaming agent, wherein the antifoaming agent is a polyalkylene glycol based antifoaming agent. The invention further relates to a process for purifying a molecule of interest from a fermentation broth comprising said method.

Abstract: The present invention is directed to a method of preparing a fermentation medium comprising the steps of a) mixing components of a fermentation medium comprising a complex nutrient source in water, wherein the complex nutrient source is in an amount of 0.5-30% w/v of the fermentation medium; b) adjusting the pH of the fermentation medium obtained in step a) to a pH between pH 3.0 and pH 6.7; c) subjecting the fermentation medium subsequently to a heat treatment and thereafter adjusting the pH to a pH value suitable for cell cultivation. The present invention is further directed to a method a fermentation process comprising cultivation of the cells in the fermentation medium of the invention and the production of a compound of interest. The present invention is further directed to a method for reducing color formation and viscosity during fermentation medium preparation and during the fermentation process.
