Brown mercury-producing bacterium in Medical News Today

“What is not known are the genes or the proteins that allow these bacteria to mediate the transformation,” said ORNL’s Steven Brown, who led a research team to sequence the genome of a bacterium in the Desulfovibrio genus that is capable of methylating mercury. The new genome, sequenced at the California-based DOE Joint Genome Institute… [Read More]

Brown mercury-producing bacterium in ScienceDaily

Desulfovibrio desulfuricans strain ND132 is an organism that thrives in sediments and soils without oxygen — the places in lakes, streams and wetlands where mercury contamination is converted to methylmercury. It is representative of a group of organisms that “breathe” sulfate instead of oxygen and are largely responsible for mercury methylation in nature. “This is… [Read More]

ORNL collaboration to understand methylmercury production

Mercury pollution in aquatic environments has been a concern, though the contaminants are mainly sourced from industrial processes and fossil fuel combustion. Isolated from Chesapeake Bay sediment, the sulfate-reducing bacterium, Desulfovibriodesulfuricansstrain ND132, can also produce the human neurotoxin methylmercury. “What is not known are the genes or the proteins that allow these bacteria to mediate… [Read More]

Cheryl Kerfeld presents ASBMB award lecture

Cheryl A. Kerfeld, a structural biologist and the head of the U.S. Department of Energy Joint Genome Institute’s Education and Structural Genomics Programs, has won the American Society for Biochemistry and Molecular Biology’s Award for Exemplary Contributions to Education. Kerfeld will present her award lecture, titled “Sequence and Consequence,” at 12:30 p.m. on April 10… [Read More]

DOE JGI’s Cheryl Kerfeld among 2011 ASBMB awardees in Washington DC

Cheryl A. Kerfeld, a structural biologist and the head of the Department of Energy Joint Genome Institute’s Education and Structural Genomics Program, won the ASBMB Award for Exemplary Contributions to Education. Kerfeld, who also serves as an adjunct professor at the University of California, Berkeley, was named the winner for encouraging effective teaching and learning… [Read More]

Fungal Genomics blog re DOE JGI User Meeting

Personally, my favorite talk at the last 6th Annual DOE JGI Users Meeting at Walnut Creek was Rob Knight‘s contribution on ‘Spatially and Temporally Resolved Studies of the Human Microbiome‘. Rob was creative and integrative. Displaying the biogeography of bacterial communities on the human body using UniFrac and QUIME was astounding. Read more at the… [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]

Finding cellulases in sediment from a paper mill

During the DOE JGI User Meeting held in Walnut Creek, Calif. from March 22-24, 2011, collaborator Daniel Distel noted that more than 20 enzymes are needed to break down cellulose. To assist in identifying novel cellulose degraders and thus improve cellulosic biofuel production processes, a team of DOE JGI researchers including Microbial Program head TanjaWoyke… [Read More]

Tasmanian devils at DOE JGI User Meeting in GenomeWeb

As part of the large-scale conservation effort he calls “Project Ark,” Schuster and his team intend to genotype hundreds of Tasmanian devils, he told attendees of the sixth annual Department of Energy Joint Genome Institute User Meeting held in Walnut Creek, Calif., this week. To date, he said, devil tumor facial disease does not seem… [Read More]
