Since then, the improvement of new heterologous protein production systems via E. coli enabled the commercial approval of several other products, including hormones (calcitonin, parathyroid hormone, human growth hormone, glucagon, and somatropin), interferons, and interleukins (Ferrer-Miralles et al., 2009). Future challenges such as finding new ways to combat disease, reduce pollution and feed the world's population. For example, approximately 30% of commercially available recombinant proteins are currently produced in prokaryotic systems (Overton, 2014). The microorganisms are then grown on an industrial scale to synthesize products such as insulin, vaccines, and biodegradable polymers. In the future, breads and pastas of the better quality can be obtained in less time. In some cases the production results from an apparent accident in nature where an organism manufactures many thousands of times the amount necessary for its own metabolism. 35, 6474.

Recent developments such as the discovery of functional xylose isomerases (Kuyper et al., 2005) resulted in the creation of new yeasts capable of fermenting 5-carbon (C5) sugars, as well as 6-carbon (C6) sugars. 10, 346358. Anal. Inactivated vaccines are currently available for hepatitis A, rabies, cholera, influenza, poliomyelitis (Salk), typhoid fever, and pertussis. J. The microorganisms are then grown on an industrial scale to synthesize products such as insulin, vaccines, and biodegradable polymers. The metabolic engineering of molecules from microorganisms has been stimulated mainly by the need for new functional biomaterials in emerging drugs (nanostructured or not) (Vzquez and Villaverde, 2013). Currently, research efforts have focused on integrating the treatment of solid wastes or even wastewater with the use of microbial fuel cells (MFC), i.e., microbial cells that use electrons donated by low-value organic substrates, contained in the waste, to generate energy (Xu et al., 2016). Prog. Chim. BioControl 58, 715722. (2016). (2010). The Egyptians, who already used yeast to brew beer, began to employ this microorganism to make bread. Ahmad, S., Abbas, S. S., Prakash, R., Alam, A., and Husain, M. A. 48, 371395. 2, 854858. Metagenomics and metatranscriptomics allow researchers to study genes and gene expression from a collection of multiple species, many of which may not be easily cultured or cultured at all in the laboratory.
