CSP 2012 announcement in GenomeWeb Daily News

The Department of Energy’s Joint Genome Institute has chosen 41 research projects out of 152 applicants to use its sequencing services under its 2012 Community Sequencing Program, JGI said Thursday.Researchers for this year’s CSP program, which provides the scientific community with access to JGI’s high-throughput sequencing technologies, proposed projects to study plant-microbe interactions, how microbes… [Read More]

Toward a Better Understanding of Soil-Microbe Interactions

In the August 2011 issue of the Journal of Bacteriology, a team of researchers led by DOE JGI’s Patrick Chain at Los Alamos National Laboratory focused on a microbe that can help or harm as the case may be. Ochrobactrum anthropi thrives in a variety of habitats including polluted soil, plants and even higher mammals…. [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]

Comparative genomics of social amoebae

Found in soils worldwide, slime molds such as Dictyosteliumdiscoideumare perhaps best known by their behaviors in the presence or absence of food. When food is plentiful, the social amoeba behave as individuals, but when food is scarce, they come together to form multicellular “fruiting bodies” that look like a flower bud atop a single stalk… [Read More]

A highly adaptable bacterium that can thrive alone or in symbiosis

Variovorax paradoxus is a β-proteobacterium typically found in the region where the plant roots interact with soil and has the ability to engage in mutually beneficial interactions with both plants and other bacterial species. The bacterium also has the ability to break down a wide range of contaminants including pesticides and crude oil compounds, and… [Read More]

A bacterium for breaking down dioxins

Isolated from the River Elbe in Germany, Sphingomonas wittichii RW 1 belongs to a family of bacteria that play a role in breaking down complex aromatic compounds associated with decaying plant mater and chemical pollution. S. wittichii itself is capable of completely breaking down toxic dioxin pollutants, and was selected for sequencing by the DOE… [Read More]

Terephthalate-degrading consortia

Terepthalate is the byproduct of a common compound used extensively by the plastics industry. The volume of terephthalate wastewater generated is equivalent to the amount of wastewater generated by 20 million people. Syntrophic communities are composed of bacteria that break down organic matter and methanogens that remove the hydrogen released to ensure the degradation process… [Read More]

Shewanella research on Environmental Protection

Researchers have completed the first thorough, system-level assessment of the diversity of an environmentally important genus of microbes known as Shewanella. Microbes belonging to that genus are used to confine and clean up contaminated areas in the environment. The team of researchers from the Georgia Institute of Technology, Michigan State University and the Pacific Northwest… [Read More]

Stinky bacteria for cleaning radioactive metals in AZ mine

Wall and her team are investigating the basic genetics and metabolism of these bacteria. They are building on discoveries funded by the Department of Energy’s Joint Genome Institute that has sequenced the genomes of about 14 strains and is working on a dozen more. With a roadmap of the 3,570,858 base pairs of DNA from… [Read More]

Shewanella, Systems Biology and Bioremediation

In the past, a great deal of bacterial classification has been based on phenotype, physiology, and comparisons between known species. But the genetic aspect of this classification has usually been limited to sequence data from 16S rRNA genes. Now, researchers are integrating information from genomic and proteomic work to clarify this bacterial classification. “The powerful… [Read More]
