Bacteria's conflicts fuel synthetic ecology research

August 18, 2015, Pacific Northwest National Laboratory

A common characteristic in mixed populations of microbes is that some bacteria, the "cooperators," dominate over others, the "cheaters." Cheaters use resources cooperators make and share. The result? The community suffers from depleted common resources.

In a June 26 Science magazine Perspective article, Pacific Northwest National Laboratory Fellow Jim Fredrickson took on the tragedy of the commons in diverse . Understanding how these interact could help scientists design synthetic communities for use in biotechnology, turning tragedy into progress.

In the article "Ecological communities by design," Fredrickson discusses how synthetic ecology—the design and construction of microbial communities with desirable properties—requires new knowledge on how communities function. The bottom line: studying such interactions can help scientists identify principles that can be used to design microbial communities for biomass conversion to biofuels and other processes.
