Toward a Genomic Encyclopedia of Fungi

Fungi are key components of terrestrial ecosystems and help maintain the interactions between a myriad of species of animals, plants and bacteria that make up these environments. With the ability to thrive in a wide variety of ecological niches, fungi are essential to the global carbon cycle, and the enzymes and metabolites they produce are… [Read More]

DOE JGI’s Community Sequencing Program Project Call in GenomeWeb

The Department of Energy’s Joint Genome Institute said today that it is now accepting letters of intent from researchers seeking to use the genomics technologies available through its Community Sequencing Program (CSP). JGI’s sequencing program provides the scientific community with access to a range of high-throughput technologies for use in large-scale sequence-based genomic projects that… [Read More]

UCLA team makes isobutanol from cellulose on ScienceDaily

While there were many possible microbial candidates, the research team ultimately chose Clostridium cellulolyticum, which was originally isolated from decayed grass. The researchers noted that their strategy exploits the host’s natural cellulolytic activity and the amino acid biosynthetic pathway and diverts its intermediates to produce higher alcohol than ethanol. The researchers also noted that Clostridium… [Read More]

Cow rumen metagenome study in EarthSky

Enter: the cow. If cows are good at anything, it’s digesting plant material until it turns into sugar; Dr. Rubin noted that cows have been eating grass for a few million years. That’s why Rubin’s team decided to do major genetic analysis of microbes inside the stomachs of cows. He explained that he was interested… [Read More]

Rumenating on improving biofuel production

Developing alternative fuels from plants has been challenging in part due to the high costs associated with processing plant biomass to more easily convert it into sugars and from there into biofuels. Ruminants such as the cow, however, can eat more than a hundred pounds of plant matter a day and break it down.  Switchgrass… [Read More]

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 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 on Times Live

They used new genetic sequencing techniques to find microbes that make enzymes that in turn can break down tough grasses into usable products. Writing in the journal Science on Thursday, they said they took samples directly from the rumen — the organ in cattle that ferments and breaks down grass. Read more on Times Live… [Read More]
