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

t energy and carbon from wisps of gases such as carbon monoxide and dimethylsulfide that blow into the desolate mountain area. The process wouldn't give the bugs a high-energy yield, Lynch said, but it could be enough as it adds up over time. A paper on the findings has been accepted by the Journal of Geophysical Research-Biogeosciences, published by the American Geophysical Union.

While normal soil has thousands of microbial species in just a gram of soil, and garden soils even more, remarkably few species have made their home in the barren Atacama mountain soil, the new research suggests. "To find a community dominated by less than 20 species is pretty amazing for a soil microbiologist," Schmidt said.

He has studied sites in the Peruvian Andes where, four years after a glacier retreats, there are thriving, diverse microbe communities. But on these volcanoes on the Chile-Argentina border, which rise to altitudes of more than 19,685 feet and which have been ice-free for 48,000 years, the bacterial and fungal ecosystems have not undergone succession to more diverse communities. "It's mostly due to the lack of water, we think," he said. "Without water, you're not going to develop a complex community."

"Overall, there was a good bit lower diversity in the Atacama samples than you would find in most soils, including other mountainous mineral soils," Lynch said. That makes the Atacama microbes very unusual, he added. They probably had to adapt to the extremely harsh environment, or may have evolved in different directions than similar organisms elsewhere due to long-term geographic isolation.

Growth on the mountain might be intermittent, Schmidt suggested, especially if soils only have water for a short time after snowfall. In those situations, there could be microbes that grow when it snows, then fall dormant, perhaps for years, before they grow again. High-elevation sites are great places to study simple microbial communitie
