Gallery: MIT Scientists Engineer Yeast Cells to Produce More Efficient ...


In the hunt to replace petroleum, scientists are looking for more efficient ways to produce biofuels from organisms. A team of researchers at MIT have engineered yeast to manufacture the heavy alcohol isobutanol. Yeast normally creates isobutanol in small amounts, and by altering the cell so that the production takes place entirely in the mitochondria, the scientists were able to boost the amount of the chemical by 260 percent. The results of their work were published in the February 17 online edition of Nature Biotechnology.
