DEPARTMENT OF ENERGY article:
Montana State University collaborators at University of Toledo discovered a strain of algae in eastern Washington’s Soap Lake, which contains high levels of the mineral. Subsequent research showed that the lake's unique environment allows the algae to metabolise carbon dioxide very efficiently while reducing competition from other microbes. According to Fields, alkaline systems with high pH like the lake can produce some of the highest carbon dioxide utilisation rates in nature, which was one of the driving factors to investigate the microorganisms under these conditions.
“These algae are definitely what you’d call extremophiles,” or organisms adapted to extreme environments, Carlson said. “We’re still learning how to fully leverage that.”
