Arctic Microbes in a Warming World
Source: LBNL TABL
In a recently published article in Nature, Janet Jansson and her team of researchers from ESD—as well as from DOE, JGI, and the U.S. Geological Survey—studied how microbes found in permafrost respond to their warming environment. Among the findings, published in the November 7th issue of Nature, is the draft genome of a novel microbe that produces methane, a far more potent greenhouse gas than carbon dioxide. This microbe, not yet named, lives in the permafrost, and was assembled out of the collection of genomes—the metagenome—isolated from the frigid soil. The assembly challenge is similar to building one complete jigsaw puzzle from a large collection of pieces from many different puzzles.
