Bacteria able to eat plastic bottles discovered by scientists

Japanese scientists have discovered a new bacteria that can eat the most common plastic in the world.
PET is a common plastic in disposable water bottles.
It is widely used, light weight, bright colors, strong and durable, and produces 50 million tons per year worldwide.
The findings of researchers at Kyoto Institute of Technology and Keio University, published in the journal Science, may be a breakthrough in managing plastics, a well-known anti-microbial or biodegradable decomposition.
To find the bacteria, a research team collected 250 pets.
Contaminated samples, including deposits, soil and wastewater from plastic bottles recycling sites.
They screened the microorganisms on the samples to investigate if any of them had eaten a pet and used it to grow.
They found a microbial group that seemed to break down the PET membrane, but only one of the bacteria, sakaiensis namdideonella, was responsible for PET degradation.
Further tests showed that bacteria used enzymes to break down PET and produce intermediate chemicals.
This chemical is then absorbed by the cells, and other enzymes are further decomposed to provide the bacteria with the carbon and energy they need to grow.
This study found that if the temperature of 29C is maintained, a sakaiensis Ideonella community can break down a layer of PET film within six weeks.
Although previous studies have found fungal species that can grow on PET, this is the first time that microorganisms that can consume this substance have been found.
This revelation makes experts question whether it is possible to be the answer ever.
More and more plastic eventually enters the environment and destroys the Earth.
Almost one pet.
However, according to the World Economic Forum, the annual output of plastics in the world is the sixth of 0. 311 billion tons (WEF)
More than half of them are recycled and much less reused.
In addition, according to The Guardian, there is a third final entry into the environment of all plastics, with 8 million tons of final entry into the ocean each year.
However, Tracy Minser, who studies marine plastics at the Woods Hall Institute of oceans in Massachusetts, explained that although the study was impressive, it is not clear whether the finding will help plastics stay away from the ocean, or become a replacement for landfill sites.
Dr. minther said: \"When I think clearly, I really don\'t know where it will take us.
I don\'t see how microorganisms can degrade plastics better than putting plastic bottles in the recycle bin so they can be melted to make new plastic bottles.
But he said the study could make it easier to identify other microorganisms that may have similar pets --
Ability reduction.
\"This process can be very common.
Now that we know what we are looking for, we may see these microorganisms in many places around the world.
