Boosting knowledge of nitrogen-fixing bacteria

No plant is an island; interactions with complex microbial communities both above the ground and below the ground shape the plant’s growth rates and overall health. Understanding these plant-microbe interactions can lead to improvements in plant health and productivity and carbon sequestration, which can be applied toward DOE missions in bioenergy and biogeochemistry.

Permafrost soil metagenome study in Wired UK

As permafrost thaws, trapped frozen organic matter becomes accessible for microbes to degrade, releasing greenhouse gases as a byproduct. Understanding what sorts of microbes are in the ice is key to predicting the impact of the melting of permafrost soils.The US Department of Energy has teamed up with the Joint Genome Institute, the Earth Sciences Division of… [Read More]

Permafrost soil metagenome study on Examiner.com

The carbon dioxide contained in the polar caps is estimated to be 1,672 billion metric tons. The slow but steady melting of the polar regions from global warming has and will continue to release more carbon as carbon dioxide as the ice sheets melt.More interesting and more potentially dangerous is the effect that melting ice… [Read More]

Permafrost soil metagenome study in Alaska Dispatch

Researchers have carted chunks of Alaska permafrost off to California, where have learned that allowing the once frozen soil to thaw wakes up hungry microbes, according to newscientist.com, which also offered a cautionary tale. Read more in the Alaska Dispatch [Read More]

Permafrost soil metagenome study in Discover

What’s the News: Melting  permafrost in a warming world could mean lots of greenhouses gasses, especially methane, released into the atmosphere. But it also means an unusual community of soil bacteria coming out of hibernation, so to speak. A new study looks at what those permafrost microbes do, exactly, as their environment warms up. Read… [Read More]

Structural Analysis of Cow and Hoatzin Microbial Communities

Inside the guts of many animals, microbes break down the plant fibers ingested as part of their diet. These microbes are of interest to bioenergy researchers who want to learn from nature and apply these cellulosic degradation capabilities toward biofuel production. To this end, at the JGI, several sequencing projects have focused on the microbial… [Read More]

Tringe DOE Award in BioPortfolio

DOE’s Office of Science awarded the Early Career Research grant to Susannah Green Tringe, a researcher in the Lawrence Berkeley National Laboratory’s Genomics Division, to study how microbial communities in restored wetlands may impact long-term carbon sequestration, from a genomic perspective.

Tringe DOE Award in Technology Today

Susannah Tringe of the Genomics Division and DOE’s Joint Genome Institute. Tringe investigates the sequencing and characterization of natural communities of microbes and their roles in processes ranging from biomass degradation to efficient production of biofuels from non-food crops. Her Early Career award from the Office of Biological and Environmental Research is for her proposal “Microbial… [Read More]

Eisen blogs Twitter wrap-up of the DOE JGI User Meeting

Off to another meeting so don’t have time to write up details of the JGI User Meeting that just ended.  But I am posting my tweets and some related tweets here.  Also, apparently videos of the talks will be available soon. Will try to clean up the style of the posts ASAP but on the… [Read More]

Stressed metagenome study on Pollution Online

“We are looking to better understand the evolution of microbes in the groundwater plume,” Watson said. “The microbes that can break down nitrate into nitrogen can have a long-term benefit toward attenuating the plume.”  Watson added that researchers particularly want to better understand the genetic makeup of microbes that can metabolize oxidized forms of uranium… [Read More]
