Patent number: 11661614Abstract: A fermentation process for producing magnesium lactate from a carbon source including the steps of: providing a fermentation medium including a fermentable carbon source in a fermentation reactor; fermenting the fermentation medium by a lactic acid producing microorganism in the presence of an alkaline magnesium salt to provide a fermentation broth including magnesium lactate; and recovering solid magnesium lactate from the magnesium lactate containing fermentation broth, wherein during at least 40% of the operating time of the fermentation process, the concentration of solid magnesium lactate in the fermentation broth is maintained in the range of 5-40 vol. %, calculated as solid magnesium lactate crystals on the total of the fermentation broth. The process allows stable operation at high productivity, in combination with efficient product separation.Type: GrantFiled: January 13, 2021Date of Patent: May 30, 2023Assignee: PURAC BIOCHEM BVInventors: Aliaksei Kalbasenka, Jeroen Bokhove

Patent number: 11136602Abstract: A fermentation product manufacturing process includes fermenting under fermentation conditions in an aqueous fermentation medium in a fermentation reactor a carbohydrate source with a microorganism capable of converting the carbohydrate into a fermentation product which is a salt or a product with a boiling point above the boiling point of water, during the process withdrawing part of the medium including biomass from the reactor in the form of a recycle stream, providing the stream including biomass to a pressure vessel wherein the pressure is such that the temperature of the stream decreases 1-8° C., as compared to the temperature of the medium in the reactor, by the evaporation of water, and recycling the cooled recycle stream to the reactor. The process makes it possible to obtain a homogeneous temperature profile of the fermentation medium with limited occurrence of hot or cool spots within the reactor which results in improved fermentation performance.Type: GrantFiled: November 29, 2017Date of Patent: October 5, 2021Assignee: PURAC BIOCHEM BVInventors: Andre Banier De Haan, Jeroen Bokhove
