Publication number: 20120264948Abstract: Methods and systems for separating and purifying monatin are described. In the production of monatin, a mixture is formed which includes monatin, starting materials and intermediates. The methods and systems include a membrane having a zeta potential of from about ?19 to ?6 such that the membrane rejects greater than about 90% of the monatin. In some embodiments, the membrane is a nanofiltration membrane.Type: ApplicationFiled: December 30, 2010Publication date: October 18, 2012Applicant: Cargill, IncorporatedInventors: Brent Howard Hilbert, Trent H.

Patent number: 7888081Abstract: Methods and systems for increasing the production of equilibrium reactions are described. In some embodiments, a method comprises removing enzymes from a reaction mixture once equilibrium is achieved, selectively re-adding enzymes and reactants for driving the product-forming reaction to product, and optionally recycling stabilized intermediates, by-products and/or co-products back into the reaction mixture. In some embodiments, a method comprises purifying the desired product from a reaction mixture and selectively recycling one or more components of the reaction mixture, such as original reactants, intermediates, co-products or by-products back into the reaction mixture as desired to improve titer. Systems for implementing the methods are also provided. In some embodiments the methods and systems are implemented for increasing the production of monatin and monatin derivatives, produced in multi-step equilibrium pathways.Type: GrantFiled: May 23, 2007Date of Patent: February 15, 2011Assignee: Cargill, IncorporatedInventors: Anil Bhagwan Khare, Brent H.
