More than 2 billion tons of carbon monoxide are released in the atmosphere every year. Various bacteria and old bacteria take this in about 250 million tons, reducing carbon monoxide to a safer level. According to new studies, these microorganisms use a special enzyme called CO Dehydrogenase to extract energy from this universal but very toxic gas.

“Carbon monoxide is a powerful poison with multiple cell life, and is also a high -energy fuel and carbon source of microorganisms,” said the University of Monash University and his colleagues, Ashley Crop.
“Carbon monoxide is released in large quantities in the atmosphere, and nature and human sources contribute to the estimated 26 million tons of carbon monoxide emissions each year.”
“Nevertheless, the average carbon monoxide concentration in the atmosphere remains very low at about 100 ppb for consumption by non -biological processes and microbial oxidation.”
“Microorganism consumption accounts for an estimated 10 to 15 % of carbon monoxide removed from the atmosphere (approximately 250 million tons per year).”
In their research, the authors showed for the first time how Co -Dehydrogenase extracted carbon monoxide and power cells.
“This enzyme is used in microorganisms of our soil and water areas. These microorganisms consume carbon monoxide for their own survival, but in the process. Help me, “said Kropp.
“This was a great example of the ingenuity of microorganisms. How did life evolve how toxic toxic things are evolved,” said Devid Gillet, the University of Monache.
“These microorganisms help to clean our atmosphere. This is because carbon monoxide is indirectly greening gas in opposition to air pollution that kills millions of people every year. Reduce warming.
“This discovery is unlikely to be used directly to fight the emissions of carbon monoxide, but deepen understanding of how the atmosphere is regulated and how it will respond to future changes. Nothing.
“This discovery emphasized the wider importance of microorganisms,” said Professor Chris Green at the University of Monash.
“Microorganisms have countless roles that are indispensable to both human and planet health, but they are often misunderstood and are often misunderstood, so they are often noticed.”
“Microorganisms were a major reason for our air,” said Kropp.
“We breathe, detoxify various pollutants, such as carbon monoxide, and make half of oxygen to detoxify.”
Survey results It will be displayed in the journal Natural chemical student。
