plastic-eating bacteria could save the earth: scientists discover bugs that can break down damaging plastics - polyethylene terephthalate film
One day, a tiny micro-organism can help us fight against the 50 million tons of pet we produce each year.
The polybendiester used in most disposable water bottles is considered to be one of the most damaging plastics in the world.
Researchers have found a potentially bacteria-saving planet that thrives on plastic and can break it down for consumption.
The study, published in the journal Science, wrote that scrolling down to watch the video "The spread of plastic in consumer goods, from bottles to clothing, has resulted in the release of countless tons of plastic into the environment . ".
"The new species, sakaiensis Ideonella, breaks down the plastic by using two enzymes to hydrolysis PET and one primary reaction intermediate, eventually producing the basic components for growth.
Also used for other products such as polyester clothing, frozen food
Tray and blister packaging.
But the material was invented 70 years ago, which led researchers to believe that bacteria evolved the ability to break down and consume bacteria.
According to Science USA, research led by Kohei Oda of Koto Institute of Technology and Kenji Miyamoto of Keio University analyzed 250 of the PET bottle recycling plant in Japan
This is where the team found bacteria on plastic film, which they call Ideonella sakainesis-after the city where plastic film was found.
After observing the microorganisms, the researchers learned that it used a pair of enzymes to decompose the pet into a mono in the middle (2-hydroxyethyl)
To benzene diacid or MHET.
The other is called MHETase, which decomposes MHET into a monomer of dibenic acid and ethylene glycol.
By screening the natural microbial communities exposed to PET in the environment, we isolated a new bacteria-sakaiensis201-
The researchers said F6 was able to use PET as its primary source of energy and carbon.
The Los Angeles Times reported that when a bacteria is locked on a pet's surface, it releases an enzyme that produces an intermediate chemical and is then consumed.
The second enzyme further breaks down into carbon, providing more energy for bacteria.
When the strain grows on PET, two enzymes capable of hydrolysis of PET and reaction intermediate mono (2-hydroxyethyl)
2 acid of benzene
Both of these enzymes require the efficient conversion of PET enzymes into two organisms that are harmless to the environment-p-benzene diacid and ethylene glycol.
Researchers believe that a large group of Ideonella sakainesis has the ability to break down PET Films in just six weeks only if the temperature is kept at 86 degrees Fahrenheit.
The plastic was not sold completely by other researchers. Eat bacteria
Although impressive, for example, they think it is not clear whether this will help plastic stay away from the ocean.
Tracy Minser says I really don't know where it will take us when I think it clear. He studied plastic in the ocean at the Woods Hole Marine Institute in Massachusetts.
"I don't think it's better for microorganisms to degrade plastics than to put plastic bottles in recycling bins so they can be melted to make new plastic bottles.
Minger hopes that these findings can lead to the discovery of other microorganisms with similar ability to decompose pets.
The process may be quite common, he said.
Now that we know what we are looking for, we can see these microorganisms in many places around the world.
