According to foreign media reports, American scientists said that the enzyme produced by a nitrogen-fixing bacteria that exists in the soybean root may be the key to realizing the dream of a new car powered by air. The enzyme name is vanadium nitrogenase, which also converts carbon monoxide (CO), a common industrial by-product, into propane.
Nitrogen-fixing bacteria convert carbon monoxide into fuel
Propane is a kind of gas that ignites to form a blue flame, and the gas discharged from all American furnaces contains propane. Vanadium nitrogenase can usually produce ammonia from nitrogen. Scientists warn that the study is still in its early stages, but they also said that the study may eventually lead to new, environmentally friendly fuel production methods, eventually extracting gasoline from thin air. Markus Ribbe, a scientist at the University of California, Irvine, who was involved in the implementation of the study, said: "This microorganism is a very common soil bacterium. We have a deep understanding of it and have implemented it for a long time. the study."
The results of the study are published in the latest issue of the journal Science. Ribec added, "Although we are still studying vanadium nitrogenase, we know that this enzyme has unusual characteristics." The name of the microorganism the scientist studied was Azotobacter vinelandii, which is very environmentally friendly. An important bacterium, it is usually found in soil around the roots of nitrogen-fixing plants such as soybeans.
The reason why farmers are particularly fond of plants that contain brown nitrogen-fixing bacteria is because this type of bacteria can make full use of multiple enzymes and turn unused nitrogen in the atmosphere into important ammonia and other compounds. Next, other plants absorb these compounds and use them to grow. Ribey in research and collaborators isolated a nitrogen-vanadium nitrogenase enzyme to convert nitrogen into ammonia. Then they separated nitrogen and oxygen from vanadium nitrogenase and filled it with carbon monoxide.
Without nitrogen and oxygen, vanadium nitrogenase begins to convert carbon monoxide into short carbon chains of two to three atoms in length. A tri-carbon chain is often referred to as propane, which is a gas that ignites to form a blue flame. All American stoves are used. Jonas Peters, a scientist at California Institute of Technology, said that scientifically speaking, the new function of vanadium nitrogenase is a "significant discovery."
It takes time for air to change to gasoline
Ribey said: "Obviously, if we can make longer carbon-carbon chains, this discovery will eventually allow us to develop synthetic liquid fuels." The new enzyme can only form two or three carbon chains instead of forming a liquid state. Longer chain of gasoline. However, Ribeh believes that he can make changes to vanadium nitrogenase so that it can generate gasoline. If this technology is further improved, it may eventually enable the car to use its own exhaust emissions as part of the fuel. After a longer period of research, the car can even “absorb†carbon dioxide from the air for the fuel it operates on, and now it has a technology to convert carbon dioxide into carbon monoxide.
Ribec and Peters both said that this step cannot be achieved in the near future. Ribey said: “Extracting vanadium nitrogenase is very difficult.†Because of its importance in agriculture, scientists have learned about this enzyme long ago. They segregated the genes for vanadium nitrogenase even more than 20 years ago, creating conditions for genetic engineers and synthetic biologists to understand the enzyme in depth. However, the technology for the extraction, growth, and storage of vanadium nitrogenase has not been developed until recent years, making this latest research possible. Before developing vehicles that use air and bacteria as fuel, scientists must conduct further research.
