Sandstone Bacteria thrives on oil iron
2013-12-19 08:32:10

April Flowers for redOrbit.com - Your Universe Online Able to withstand high heat, high salinity, low oxygen, utter darkness and pressures that would kill most other organisms, the bacteria Halomonas is a very hardy breed. Traits such as these enable these microbes to eke out a living in deep sandstone and have proven to be useful for hydrocarbon extraction and carbon sequestration. The new study, published in Environmental Microbiology, gives the first unobstructed view of the...

Domestic Dogs Offer Protection From Asthma And Infection: Study
2013-12-17 11:46:04

[ Watch the Video: Pet Dogs May Shield Kids From Later Allergies ] Brett Smith for redOrbit.com - Your Universe Online Previous research has shown that children who grow up in a house with a dog are less likely to develop severe allergies and now a new study from an American team of researchers has found that gut bacteria may play a role in that relationship. According to a study published Monday in the Proceedings of the National Academy of Sciences (PNAS), mice that were exposed to...

Transferring the gut microbes from a mouse with colon tumors to germ-free mice makes those mice prone to getting tumors as well, according to the results of a study published in mBio®, the online open-access journal of the American Society for Microbiology. The work has implications for human health because it indicates the risk of colorectal cancer may well have a microbial component. "We know that humans have a number of different community structures in the gut. When you think about...

Most of us wouldn't consider bacteria a promising energy source of the future. That would be shortsighted, says Leonard Tender, a microbial-electrochemist at the Naval Research Laboratory in Washington, D.C., who believes that the focus of his research – electrode reactions catalyzed by microorganisms – may one day provide cheap, clean and abundant energy by converting the carbon dioxide in seawater to fuel and the organic matter in wastewater into electrical power. Tender will discuss...

Methane Seeps Of The Deep Sea Are A Bacteria Feast For Lithodid Crabs
2013-10-08 09:54:33

Helmholtz Centre for Ocean Research Kiel (GEOMAR) Photos and analyses reveal more about a highly specialized food web The bottom of the deep sea is largely deserted. Oases occur for example at cold seeps where water transports dissolved elements from the seabed: Specialized microbes convert methane and sulfate from sea water to hydrogen sulfide releasing carbon dioxide. Highly adapted bacteria, many of which live in symbiosis with worms and clams, use the hydrogen sulfide for their...

Bacterium Found In Termite Guts Helps Make Wood A Nutritious Meal
2013-09-27 08:15:23

April Flowers for redOrbit.com - Your Universe Online As termites eat wood, the small chunks they chew off are delivered to feed a community of unique microbes living in their guts. In a complex multi-step process, these microbes turn the hard, fibrous material of the wood into a nutritious meal for the termite host. A key step in this process uses acetogenesis -- where hydrogen converts carbon dioxide into organic carbon. It is unknown, however, which gut bacteria play specific roles in...

Next Generation Of Medicine Could Come From The Oceans
2013-09-02 12:21:36

Lee Rannals for redOrbit.com - Your Universe Online Scientists are starting to look to the ocean to find the next generation of medications that could help yield a variety of cures. The SeaBioTech project launched in 2012 with the hope of finding raw material for the world's biotechnology industry -- specifically new antibiotics and other medical compounds. “The oceans can be deep or shallow, they can be more or less tidal, and they can include unique environments such as volcanic...

1 species of bacteria rides the other down through sediment like an elevator, then closes the loop on the ocean's nitrogen cycle In a discovery that further demonstrates just how unexpected and unusual nature can be, scientists have found two strains of bacteria whose symbiotic relationship is unlike anything seen before. Long, thin, hairlike Thioploca (meaning "sulfur braids" in Spanish) trichomes form chains down into marine sediment, which tiny anammox cells ride down like an...
