CU-Boulder-led team finds microbes in extreme environment on South American volcanoes
Date:6/8/2012

A team led by the University of Colorado Boulder looking for organisms that eke out a living in some of the most inhospitable soils on Earth has found a hardy few.

A new DNA analysis of rocky soils in the Martian-like landscape on some volcanoes in South America has revealed a handful of bacteria, fungi and other rudimentary organisms called archaea, which seem to have a different way of converting energy than their cousins elsewhere in the world.

"We haven't formally identified or characterized the species," said Ryan Lynch, a CU-Boulder doctoral student involved in the study. "But these are very different than anything else that has been cultured. Genetically, they're at least 5 percent different than anything else in the DNA database of 2.5 million sequences."

Life gets little encouragement on the incredibly dry slopes of the tallest volcanoes in the Atacama region, where CU-Boulder Professor Steve Schmidt and his team collected soil samples. Much of the sparse snow that falls on the terrain sublimates back to the atmosphere soon after it hits the ground, and the soil is so depleted of nutrients that nitrogen levels in the scientists' samples were below detection limits.

Ultraviolet radiation in the high-altitude environment can be twice as intense as in a low-elevation desert, said Schmidt of CU-Boulder's ecology and evolutionary biology department. While the researchers were on site, temperatures dropped to 14 degrees Fahrenheit one night and spiked to 133 F the next day.

How the newfound organisms survive under such circumstances remains a mystery. Although Ryan, Schmidt and their colleagues looked for genes known to be involved in photosynthesis and peered into the cells using fluorescent techniques to look for chlorophyll, they couldn't find evidence that the microbes were photosynthetic.

Instead, they think the microbes might slowly generate energy by means of chemical reactions that extrac
