21.1 Metabolic Engineering

Metabolic engineering focuses on improving cellular activities as an applied science by the use of recombinant DNA technology [1]. Metabolic engineering has been advanced as an effective tool for improving industrial fermentation processes [2]. As cell factories, engineered microbes constructed by designing metabolic pathways can convert carbon sources such as sugars into value-added chemicals and food materials [3] (Figure 21.1). Numerous genetic and computational tools enabling modification, analysis, and prediction of metabolic fluxes have been developed in recent years.
