Cow rumen metagenome study on COSMOS Magazine

The result was 270 billion base pairs of genetic code, almost a hundred times more than the human genome, and an estimated two million potential genes to be investigated. To find which bacteria could digest cellulose, the researchers compared codes with known regions of Carbohydrate Active Enzymes called CAZymes. “Regions include domains that bind cellulose… [Read More]

Cow rumen metagenome study in R&D Magazine

In the new study, the researchers focused on switchgrass, a promising biofuels crop. After incubating the switchgrass in the rumen for 72 hours, researchers conducted a genomic analysis of all of the microbes that adhered to switchgrass. This “metagenomic” approach, led by Edward Rubin, of the DOE Joint Genome Institute and the Lawrence Berkeley National… [Read More]

Cow rumen metagenome study on Mother Nature Network

Ethanol makers will produce about 13 billion gallons of the renewable fuel this year, chiefly from corn. A 2007 law requires annual use of 36 billion gallons from 2022 and reserves 21 billion gallons of it for “advanced” biofuels.   The U.S. government offered $1.5 billion in October to help bring next-generation biofuels to market….

Cow rumen metagenome study on Scicasts

“The problem with second-generation biofuels is the problem of unlocking the soluble fermentable sugars that are in the plant cell wall,” said University of Illinois animal sciences professor Roderick Mackie, an author on the study whose research into the microbial life of the bovine rumen set the stage for the new approach. “The cow’s been… [Read More]

Cow rumen metagenome study in Technology Review

The first step in cellulosic biofuels is converting tough plant materials made of cellulose and lignin into sugars that can then be fermented to make fuels. But this is expensive and currently requires a large quantity of enzymes to break down cellulose. “We’re talking truckloads,” says Frances Arnold, a professor of chemical engineering at Caltech… [Read More]

Cow rumen metagenome study on ClimateWire

Scientists hunting for ways to drive down the cost of converting plant waste into fuel may have found some valuable clues in the bellies of cows. Researchers employing high-tech genetic sequencing methods identified dozens of gut-dwelling organisms that help cows break through the protective sheath that guards the sugars inside plants. Some of these enzymes… [Read More]

UI on cow rumen metagenome study in ScienceDaily

The study, in the journal Science, tackles a major barrier to the development of more affordable and environmentally sustainable biofuels. Rather than relying on the fermentation of simple sugars in food crops such as corn, beets or sugar cane (which is environmentally costly and threatens the food supply) researchers are looking for better ways to… [Read More]

“The problem with second-generation biofuels is the problem of unlocking the soluble fermentable sugars that are in the plant cell wall,” said University of Illinois animal sciences professor Roderick Mackie, an author on the study whose research into the microbial life of the bovine rumen set the stage for the new approach. “The cow’s been… [Read More]

Cow rumen metagenome study in Scientific American

“If the industry is going to move forward, it’s going to need new enzymes,” says Eddy Rubin, the director of the U.S. Department of Energy’s Joint Genome Institute. Rubin and 16 colleagues report in the January 28 issue of Science how they discovered nearly 30,000 new enzyme candidates by analyzing DNA collected from a cow’s… [Read More]

Schizophyllum commune project on PhysOrg

The DOE Joint Genome Institute (JGI) previously sequenced and published the genomes of two wood-decaying fungi. Now a team of researchers led by scientists from the DOE JGI and the University of Utrecht announce the analysis of a third such genome in a study published online July 11 in Nature Biotechnology. All told, DOE JGI… [Read More]
