Roberts Wesleyan College part of DOE JGI Undergraduate Research Program in Microbial Genome Annotation

The U.S. Department of Energy Joint Genome Institute (JGI) has chosen Dr. David Roll, professor of biological chemistry and director of Forensic Science at Roberts Wesleyan College, as one of 18 collaborators nationwide to join its Undergraduate Research Program in Microbial Genome Annotation, the College announced today.

Phil Hugenholtz on metagenomics and ecogenomics in Australian Life Scientist

In research published in Nature in 2007, Hugenholtz, along with collaborators from the California Institute of Technology and Diversa (now Verenium) Corporation, used metagenomics to detail the process by which a dry wood feeding termite, a Nasutitermes species, breaks down cellulose.  They generated 62 million base pairs – a “drop in the ocean by today’s… [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]

Around this time, Dey-Rao suggested that the department become involved in educational programs offered through the Department of Energy’s Joint Genome Institute (JGI). In looking into these programs, Kostyniak concluded that they would be a good fit for university-level courses, as well as for high school courses aimed at stimulating students’ interest in science careers….

DOE JGI’s microbial work and IMG on ESNet’s Network Matters

Microbes are single-cell organisms that live in colonies and can be found in nearly every corner of our planet, in places ranging from insects’ intestines to some of the most toxic chemical environments. The site for the most detailed information on the genetic makeup of these organisms only lives in one place – at the… [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]

Cow rumen metagenome study on BBC World Service: Science in Action

Growing crops to make bio-fuel is controversial – they can take up valuable land and resources that could be used for food production and in the case of oil palms, large tracts of rainforest have been cleared to make way for this cash crop. But the second generation of bio-fuels hope to make use of… [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 GenomeWeb’s The Daily Scan

In Science this week, a team led by investigators at the US Department of Energy Joint Genome Institute reports its discovery of 27,755 putative carbohydrate-active genes among cow rumen microbes through metagenomic sequencing. The team also found that these genes “expressed 90 candidate proteins, of which 57 percent were enzymatically active against cellulosic substrates,” which… [Read More]

Cow rumen metagenome study on ABC Science

In this case, the goal was to find microbes that make enzymes that can efficiently break down the toughest fibres 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]
