ABSTRACT
Fed-batch culture is the predominant mode of the current animal cell culture process for many recombinant protein production. Fed-batch culture operation is mainly based on the nutrient continuous consumption and demand of cells to design continuous or semi-continuous concentration feed medium to maintain or support high-density cell growth and improve volumetric productivity of target protein in the reactor. The main methods to improve production efficiency of fed-batch cells culture include the optimization of medium design, selection and optimization of feed strategy and regulation of cell metabolism.
