Researcher Finds Hydrogen Production in Extreme Bacterium

03.02.2015

A researcher at Missouri University of Science and Technology has discovered a bacterium that can produce hydrogen, an element that one day could lessen the world’s dependence on oil.

Dr. Melanie Mormile, professor of biological sciences at Missouri S&T, and her team discovered the bacterium “Halanaerobium hydrogeninformans” in Soap Lake, Washington. It can “produce hydrogen under saline and alkaline conditions in amounts that rival genetically modified organisms,” Mormile says.

“Usually, I tend to study the overall microbial ecology of extreme environments, but this particular bacterium has caught my attention,” Mormile says. “I intend to study this isolate in greater detail.”

Mormile, an expert in the microbial ecology of extreme environments, wasn’t searching for a bacterium that could produce hydrogen. Instead, she first became interested in bacteria that could help clean up the environment, especially looking at the extremophiles found in Soap Lake. An extremophile is a microorganism that lives in conditions of extreme temperature, acidity, alkalinity or chemical concentration. Living in such a hostile environment, “Halanaerobium hydrogeninformans” has metabolic capabilities under conditions that occur at some contaminated waste sites.

With “Halanaerobium hydrogeninformans,” she expected to find an iron-reducing bacterium and describe a new species. What she found was a new species of bacterium that can produce hydrogen and 1, 3-propanediol under high pH and salinity conditions that might turn out to be valuable industrially. An organic compound, 1, 3-propenediol can be formulated into industrial products including composites, adhesives, laminates and coatings. It’s also a solvent and can be used as antifreeze.

The infrastructure isn’t in place now for hydrogen to replace gasoline as a fuel for planes, trains and automobiles. But if hydrogen becomes an alternative to gasoline, “Halanaerobium hydrogeniformans,” mass-produced on an industrial scale, might be one solution – although it won’t be a solution anytime soon.

“It would be great if we got liters and liters of production of hydrogen,” Mormile says. “However, we have not been able to scale up yet.”

In her first single-author article, Mormile’s findings were featured in the Nov. 19 edition of Frontiers in Microbiology.

Mormile holds two patents for her work on the Soap Lake bacterium’s biohydrogen formation under very alkaline and saline conditions. Also named on the patents are Dr. Judy Wall, Curators' Professor of Biochemistry and Joint Curators' Professor of Molecular Microbiology & Immunology at the University of Missouri-Columbia, and her former lab members, Matthew Begemann and Dwayne Elias. A pending patent application, submitted along with Elias; Dr. Oliver Sitton, professor of chemical and biochemical engineering at Missouri S&T; and Daniel Roush, then a master’s student for Mormile, is for the conversion of glycerol to 1, 3-propanediol, also under hostile alkaline and saline conditions.

This patented and patent-pending technology is available for licensing through the Missouri S&T Center for Technology Transfer and Economic Development. Contact Eric Anderson at 573-341-4690 or ericwa@mst.edu for more information.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
