Methane oxide bacteria are a leader in air purification among many microorganisms.
they absorb both the major greenhouse gases in the environment and heavy metals in the environment.
now, scientists have a new understanding of how they work.
two proteins that have never been studied, MbnB and MbnC, have been identified as affecting the internal functioning of these bacteria in part.
these physiological processes allow methane oxide bacteria to help us cope with climate change.
the structure of the MbnB protein.
photo source: Amy Rosenzweig Lab, Northwestern University, according to a new study published recently in Science, once we have a better understanding of how these bacteria work, we can use them to complete important environmental clean-up tasks and even treat diseases. "Our findings go far beyond methane oxide itself," said Dr. Amy Rosenzweig of Northwestern University,
paper's lead author.
both proteins are also found in other bacteria, including human pathogens.
" that's why MbnB and MbnC are important: they are responsible for producing a modified peptide called methane peptide, which allows bacteria to absorb copper from the environment.
then used copper as a fuel to inhale methane oxide bacteria and convert it into methanol for food.
this process has made scientists so interested in the bacteria, and MbnB and MbnC are responsible for initiating this chain of reactions.
combined with higher levels of carbon dioxide, increased levels of methane in the atmosphere are also a major driver of global warming.
it comes from nature, but also from the oil and gas industry.
scientists are now weighing the use of methane oxide bacteria to combat future rises in methane levels and using methane as a potential renewable energy source by converting methane into fuel.
more importantly, because methane oxycodone binds closely to copper, methane oxidizing bacteria are also used as a potential treatment for Wilson's disease, a rare genetic disease in which the body cannot properly process small amounts of copper in food, and a new probiotic made from the bacteria could be a potential treatment.
the number of studies and methods of research on this point are lacking, the new study could also improve our understanding of other bacterial species.
by identifying MbnB and MbnC and the processes they are involved in, scientists are better able to predict which bacteria produce which specific methane oxidizing bacteria. "An enzyme that requires metal is involved in the formation of these chemical groups, which has been unknown in the past, and neither protein has been studied in the past," said
Rosenzweig.
, similar enzymes are produced in other cases, suggesting that the importance of this chemical process is not limited to the production of methane oxidizing bacteria.
