Engineered yeast used to influence gut microbiome of mice

August 1, 2023

Scientists are becoming increasingly aware of how the human microbiome, or the collection of microbes the live on and inside of us, has a major connection to health and human physiology. Microbial engineering, which changes the structure of the microbiome through methods such as probiotics, antibiotics, and microbe transplants, has been found to be a useful strategy for improving human health, but the mechanisms underlying this improvement are still unclear and difficult to test.

Bioprocess developed for converting plant materials into valuable chemicals

August 20, 2021

A team of scientists at the University of Illinois Urbana-Champaign developed a bioprocess using engineered yeast that completely and efficiently converted plant matter consisting of acetate and xylose into high-value bioproducts.

Lignocellulose, the woody material that gives plant cells their structure, is the most abundant raw material on Earth and has long been viewed as a source of renewable energy. It  contains primarily acetate and the sugars glucose and xylose, all of which are released during decomposition.

Team uses a cellulosic biofuels byproduct to increase ethanol yield

Scientists report in Nature Communications that they have engineered yeast to consume acetic acid, a previously unwanted byproduct of the process of converting plant leaves, stems and other tissues into biofuels. The innovation increases ethanol yield from lignocellulosic sources by about 10 percent.
