Bacteria Species May Help Ethanol Output

YELLOWSTONE NATIONAL PARK, Wyo. - Scientists say a new bacteria species discovered in Yellowstone's thermal pools could improve the use of bacteria to produce ethanol.

Researchers found the bacteria in Octopus and Mushroom springs as well as in Green Finger Pool. The bacteria thrive in hot water, growing best between 120 and 150 degrees.

The discovery is rare because the bacterium is photosynthesizing, meaning it produces energy from sunlight. Scientists have discovered just three similar bacteria species within the past century, according to Don Bryant, a professor of biotechnology, biochemistry and molecular biology at Penn State University and leader of the research …
