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: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
