Permafrost metagenome study on VOA Special English report

The researchers say one gram of the soil could contain thousands of different kinds of microbes and billions of cells. They say these organisms had never before been cultured in a laboratory. JANET JANSSON:  “So more than ninety percent of those bacteria and other microorganisms in permafrost, we had no idea what they were.” Read… [Read More]

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. Dark-field photo… [Read More]

Engineering bacteria to produce biodiesel

Biodiesel production typically starts with oil-rich energy crops such as soybean, palm or rapeseed, which are harvested and then converted into fatty acids for use as fuel. The cost of expanding oilseed crop production is a limiting factor in allowing biodiesel to compete with fossil fuel sources. One alternative to using oilseed crops that many… [Read More]

Spider mite genome project in CBC News

“They can change the repertoire [of genes] that they’re using in order to be able to feed on hosts that they would not be adapted to,” said Miodrag Grbic, a University of Western Ontario biologist, who led an international project to sequence the spider mite’s genome. The results were published this week in the journal… [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]

Dark ocean project in Climate Action

To understand the world’s climate, we must understand how the 70% of the Earths surface that is covered with water behaves. Very little is known about the processes below 200m, or the area where photosynthesis is not possible due to the lack of light penetration. Scientists from the U.S. Department of Energy Joint Genome Institute… [Read More]

DOE JGI’s Prochnik in Discovery News

“This one-celled organism hunts and eats bacteria as an amoeba, swims around looking for a better environment as a flagellate, and then hunkers down and waits for good times as a cyst,” said Simon Prochnik, a computational scientist at the U.S. Department of Energy’s Joint Genome Institute. “It is a very rare process to go… [Read More]

Another Brown Mercury Producer Genome Sequenced

In the August edition of The Journal of Bacteriology, a group of scientists including several DOE JGI researchers and longtime collaborator Judy Wall of the University of Missouri described the genome for Desulfovibrio africanus, a sulfate-reducing bacterium isolated from Namibia that doesn’t require oxygen for its survival. Like the Desulfovibrio species sequenced as recently as… [Read More]

Ethanol Contaminant Could Assist Production Efficiency

An Ethanol plant in Bairstown, Iowa (Courtesy of USDA) In the August edition of The Journal of Bacteriology, researchers led by long-time collaborator David Mills of the University of California Davis, and including DOE JGI’s Alex Copeland, Olga Chertkov and Lynne Goodwin, announced the completed genome sequence of Lactobacillus buchneri and has now been made… [Read More]
