Cow rumen metagenome study on TVNZ

Identifying the enzymes that give the tiny bacteria this power could make it easier to turn switchgrass and other plant products into fuel in factories. Ethanol makers will produce about 49 billion litres of the renewable fuel this year, chiefly from corn. A 2007 law requires annual use of 136 billion litres from 2022 and… [Read More]

Cow rumen metagenome study on PlanetArk

To make sure they found the right microbes in action, they used a cow that had a hole surgically opened right into its rumen. The researchers needed to find the bacteria that worked in airless environments like a cow’s insides.Rubin’s team used metagenomics, a gene-sequencing approach that maps the DNA of a community of organisms… [Read More]

Cow rumen metagenome study on ScienceBlog

When it comes to breaking down plant matter and converting it to energy, the cow has it all figured out. Its digestive system allows it to eat more than 150 pounds of plant matter every day. Now researchers report that they have found dozens of previously unknown microbial enzymes in the bovine rumen — the… [Read More]

Cow rumen metagenome study on Bioscience Technology

“Industry is seeking better ways to break down biomass to use as the starting material for a new generation of renewable biofuels,” said JGI Director and project lead Eddy Rubin. “Together with our collaborators, we are examining the molecular machinery used by microbes in the cow to break down plant material.” Read more on Bioscience… [Read More]

Cow rumen metagenome study on Green Car Congress

Researchers have used a metagenomic analysis to discover dozens of previously unknown microbial enzymes in the bovine rumen—the cow’s primary grass-digestion chamber—that contribute to the breakdown of switchgrass, a renewable biofuel energy source. The study, reported in the current issue of the journal Science, tackles a major barrier to the development of more affordable and… [Read More]

Cow rumen metagenome study on FavStocks

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 Laboratory,… [Read More]

Cow rumen metagenome study on PhysOrg

Bovines are thought to have first appeared on the landscape millions of years ago and were domesticated by humans about 10,000 years ago. Rumen microbes evolved to produce molecular machines in the form of enzymes able to efficiently deconstruct plant cell wall polysaccharides such as cellulose and hemicellulose into their constituent small sugar molecules. Another… [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]

UI on cow rumen metagenome study in EurekAlert

“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 on Reuters

In this case, the goal was to find microbes that make enzymes that can efficiently break down the toughest fibers in switchgrass, a tough crop that can be used to produce ethanol and which can grow in places where food crops do not grow well. But switchgrass is very tough to break down. Read more… [Read More]
