Microorganisms can indeed live in extreme environments, but the ones that do are highly adapted to survive and little else, according to a collaboration that includes Department of Energy's Oak Ridge National Laboratory and Joint Genome Institute (JGI) and the University of Oklahoma. The metagenomic study of a "stressed" microbial community in groundwater near a former waste disposal pond site on DOE's Oak Ridge Reservation (ORR) revealed microbes with an overabundance of genes involved in...

The thousands of bacteria, fungi and other microbes that live in our gut are essential contributors to our good health. They break down toxins, manufacture some vitamins and essential amino acids, and form a barrier against invaders. A study published today in Nature shows that, at 3.3 million, microbial genes in our gut outnumber previous estimates for the whole of the human body. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, working within the...

Switching from warm-season grasses to cool-season forages can give livestock a belly ache, in some cases a deadly one, according to Texas AgriLife Research scientists. Dr. Bill Pinchak, Texas AgriLife Research animal nutritionist at Vernon, is leading a team of scientists who are using state-of-the-art technology "“ metagenomics "“ to determine how changes in diest affect microbial communities in the digestive tract of cattle and how these changes may increase risk of disease....

Metagenomics, the study of DNA isolated from samples of naturally occurring microbial populations, is rapidly growing. Improvements to cloning and sequencing techniques are allowing researchers to study microorganisms in environmental samples, and new knowledge of species interactions and community dynamics is emerging. The identification of microorganisms in these samples is of vital importance to interpreting the results of such studies. In the January issue of Cold Spring Harbor Protocols...

The Earth is estimated to have about a nonillion (1,000,000,000,000,000,000,000,000,000,000) microbes in, on, around, and under it, comprised of an unknown but very large number of distinct species. Despite the widespread availability of microbial genome data"”close to 2,000 microbes have been and are being decoded to date"”a vast unknown realm awaits scientists intent on exploring microorganisms that inhabit this "undiscovered country." Two thousand years after Pliny the Elder...

Large-scale genomic sequencing of microbes and ecosystems recommended for greatest impact in medicine, manufacturing Scientists can gain insights into new ways to use microorganisms in medicine and manufacturing through a coordinated large-scale effort to sequence the genomes of not just individual microorganisms but entire ecosystems, according to a new report from the American Academy of Microbiology that outlines recommendations for this massive effort. The report, "Large-Scale Sequencing:...

A team of researchers at the University of British Columbia, along with colleagues at the US Dept. of Energy Joint Genome Institute, has mapped the genome of a microbe that is silently helping to shape the ecology of oxygen-minimum areas in the ocean known as dead zones. "Microbes specialize in metabolic innovation and many can use alternatives to oxygen, including nitrates, sulfates and metals, breathing these compounds instead of oxygen. These adaptations likely enable them to thrive in...

Among the many changes in the ocean is the expansion of oxygen-deficient or oxygen minimum zones (OMZs), also known as dead zones, which affect the processes by which carbon is captured and sequestered on the seafloor and alter the microbial activities that impact the rate and magnitude of ocean carbon sequestration. Despite the importance of these effects, very little is known about the metabolism of OMZ microbes and how they respond to environmental changes. In the Oct. 23 issue of the...
