Researchers at the Missouri University of Science and Technology in the United States have discovered that a salt anaerobic genus can produce hydrogen, and in the future it may be used as one of a number of ways to make hydrogen in order to reduce world dependence on oil. The results of this study were published in the latest issue of Microbial Frontier.
According to the Physicist Organization Network on February 2 (Beijing time), Dr. Mol Miley, a biological sciences professor at the university, and his team discovered a salt-producing anaerobic bacterium capable of producing hydrogen in Lake Thorpe, Washington. (Halanaerobium hydrogenoformans). Miley said, "it can produce a certain amount of hydrogen under salt and alkaline conditions, which is more competitive than genetically modified organisms."
Miley, an expert in the study of ecology in extreme environments, originally intended to search for bacteria that could produce hydrogen. She was initially interested in bacteria that help clean up the environment, especially in the study of extreme microorganisms in Thorpe. Such microorganisms can grow under extreme conditions such as temperature, acidity, alkalinity, or chemical plant concentration. And living in such a harsh environment, the salt anaerobes still have metabolic capacity.
Miley said, "I usually study the ecology of microorganisms in the entire extreme environment, but this particular bacteria caught my attention. I tried to study this isolated population in more detail."
Studies have found that this salt anaerobic genus can produce hydrogen at high pH and salinity, as well as 1,3-propanediol, which has a certain value for industrial applications. Among them, 1,3-propanediol is an organic compound that can be made into industrial products including composites, adhesives, laminates, and coatings. It can also be made into a solvent as an antifreeze.
In the future, hydrogen can replace gasoline as a fuel for aircrafts, trains, and automobiles. The current hydrogen-producing infrastructure is not yet in place. However, if large quantities of this salt anaerobes are produced on an industrial scale, hydrogen can be used as an alternative energy source for gasoline and may be a future solution, although it cannot yet be used as an immediate solution. Miley said, “If we can upgrade hydrogen production with public facilities, we haven’t yet reached that scale.†(Reporter Hualing)
