What do skin moisturizer, anti-malarial drugs and diesel fuel all have in common? All are among several products made with genetically re-programmed yeast cells, thanks to a newly emerging science and technology field called Synthetic Biology. One of the most exciting fields in science, Synthetic Biology is a cross between biology and engineering in which blocks of DNA are custom designed, built and placed into an empty living cell to produce pre-defined chemicals. Computers are used to design and simulate specific combinations of DNA for the desired end product prior to building the DNA and implanting into empty living cells.
Yeast is the living cell of choice for this process because of its combination of relative simplicity, workability and predictable results. Human beings have enjoyed yeast’s byproducts, alcohol and carbon dioxide, for centuries for drink and baked goods. Reads like something straight out of a science-fiction novel. But it isn’t science fiction. It is happening right now.
