Lactic acid bacteria (LAB) or Lactobacillales are industrially important microbes used in a large variety of industrial processes such as food fermentation. Not only do LAB have great potentials for in situ production of fermented foods, but they also seem promising in metabolic engineering. Their contribution in fermentation processes primarily roots from the formation of lactic acid. Besides, LAB enhance other product characteristics such as flavor, texture and nutrition.

The main application of LAB in industrial processes is to serve as food starters (e.g., for dairy product, pickles, meat and wine). In addition, they are able to metabolize numerous mono- and di-saccharides. Furthermore, natural or metabolically engineered LAB produce many metabolites with confirmed applications:
Metabolic engineering is usually applied to broaden the range of carbon sources or improve its product yield and productivity, largely for food grade applications. L. lactis is the most extensively studied species among LAB, along with other species include L. plantarum, L. brevis, L. panis, and others.
