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.
描述了一种增加平衡反应产量的方法和系统。在某些实施例中,一种方法包括在达到平衡后从反应混合物中去除酶,选择性地重新添加酶和反应物以驱动生成产物的反应,并可选择性地将稳定的中间体、副产物和/或共产物循环回反应混合物。在某些实施例中,一种方法包括从反应混合物中纯化所需的产物,并选择性地将反应混合物中的一个或多个组分,如原始反应物、中间体、共产物或副产物循环回反应混合物,以提高产量。还提供了实施这些方法的系统。在某些实施例中,这些方法和系统被用于增加在多步平衡途径中产生的莫纳汀和莫纳汀衍生物的产量。
