or more targeted bodily functions beyond adequate nutritional effects in a way that improves health and well-being and reduces the risk of disease (3). Functional food ingredients include low calorie sugars, polysaccharides, and vitamins.

Applying ME principles and tools to the production of food ingredients by bacteria has resulted in the efficient production of both native and totally novel products by several cultures, including strains of lactic acid bacteria (LAB), Escherichia coli, Bacillus subtilis, and Corynebacterium glutamicum. These microorganisms have been selected based on a variety of criteria including, availability of genetic tools for cloning, expression, disruption, or replacement of genes (i.e., sequenced genome, promoters, plasmids and cloning vectors, gene transfer methods, and gene expression systems); capacity to metabolize a wide spectrum of carbon sources at high fluxes; rapid growth on inexpensive carbon and nitrogen sources; GRAS (generally regarded as safe) status; resistance to bacterio-phage attack; well established physiological knowledge; efficient transport of the final product to the extracellular medium and tolerance to its high levels; and use in large-scale fermentations and production at an industrial level. The examples in this chapter (summarized in Table 5.2) will cover the analysis and modification of central metabolic pathways, biosynthetic pathways, and transport systems involved in producing amino acids, organic acids, vitamins, carbohydrates, bacteriocins, low calorie sugars, and aroma compounds. It is worth noting that many of these products are commercially produced.
