Hearty Bacteria Help Make Case for Life in the Extreme

Hearty Bacteria Help Make Case for Life in the Extreme

Summary- The bottom of a glacier is not the most hospitable place on Earth. There are at least 2 bacteria that live there according to researchers. The bacteria is Chryseobacterium and Paenisporosarcina showed signs of respiration in ice made in the laboratory that was designed to simulate as closely as possible the temperatures and nutrient content. This is found at the bottom of Artic and Antarctica glaciers.

Critique- With the bacteria which were collected from the glaciers of Greenland and Antarctica indicated that respiration was occurring at temperatures around from negative 27 to positive 24 degrees Fahrenheit.

Impact- The glaciers and ice sheets represent large ecosystems that cover more than 10 percent of Earth. They are containing approximately 78 percent of the world’s fresh water.
