Hooray! Now can they make one that only eats Trump?

Is russian pee combustible?

@geko LOL!!

I thought that was the hookers and pornstars job?

Good maybe it will start on fossil fuel next and we will be forced to use alternatives.

Unfortunately for you, biologists in the USA have genetically modified bacteria to do the opposite - digest vegetable matter and create diesel fuel! as a waste product.
But at least it results in a more balanced ecological system.

@Petter but that's ok because it's carbon neutral. It's all the carbon we are taking from the ground with putting any back in that is the problem

@JeffB Thought that was part of the fracking process?

@JeffB Agreed. Although a lot of the carbon from the ground gets turned into a huge variety of plastics, such as paint, nylon stockings, smart phone cases, hand bags, ..... .... ....
... ... Oh! And, of course, clear plastic bottles!

@azzow2 I don't follow

@JeffB nor do I. However, I could understand "part of the F****ing purpose"!!!

Wasn't there a fungus that was discovered several years ago that eats plastic? It looked like a mushroom. I can't remember the year I read that.

Yes, but it is far slower than bacteria and more sensitive to environmental conditions.

And that's how the zombie apocalypse started kids..

Actually the article indicated that the new research was spurred by the discovery in 2016 of the first bacterium that had naturally evolved to eat plastic, at a waste dump in Japan. Scientists have now revealed the detailed structure of the crucial enzyme produced by the bug. This is perhaps further proof of evolution. Scientists are enhancing the bactreria which evolved to eat the PET plastic.

Good. Send it to the pacific

I love this !! lets hope it gets some positive use

I'd rather it went into the machine the Japanese gentleman invented to create oil, otherwise all that mining for nothing! [hoaxorfact.com]

I just start thinking of stargate and the spider thingies that ate everything !!

And what will we feed it when we are out of plastic bottles?

I'm not sure we'll ever be out of plastic bottles, sadly.

Trump's hairbrushes

3

That is exciting!

Can you imagine it eating every plastic perhaps? will it just eat the stuff we don't want anymore?

2

With further research this could solve a LOT of problems. I'm excited to keep up with it and see where the studies go.

Does the enzyme only eat plastic? Finally a solution to all the junk floating in the ocean...

2

Beware...what happens when the emzyme starts eating all the plastic in our lives? Think of all the plastic that you use everyday.

This will be very bad if it produces methane in the process. The base enzyme is already in the wild. Then again... if it does produce methane... and becomes ubiquitous in the wild, it might very well mean collecting as much PET from the environment as we can, and never making more of it. 😀

Interesting - if they could decompose and then capture the methane to produce energy in a closed system? Sounds profitable.

nom nom nom. Thanks for sharing this! It was a neat read!

Awesome!

That's probably the best news I've heard all year. Enzymes that digest plastic could be very useful to conservation efforts around the world. It creates a new way for us to get rid of trash with less detrimental effects to the environment. This just proves that nature has ways of solving our problems better than we could imagine.

it's specific to PET.

@Lukian Still, anything helps

@Fanburger Scientists ACCIDENTALLY created the enzyme. Enzymes are proteins that work in a specific way ACCORDING to the laws of nature. Scientists merely make use of the properties and manipulate them. In this case, the nature of enzyme formation yielded an unexpected result from their work. A new discovery was made. You can praise the scientists all you like, but the potential for such a creation was already in existence. It needed only someone to discover it.

@Fanburger Overreaction. Take things easier!

@Ravensasha121 You could say that about all scientific discoveries. Everything is already out there, waiting to be discovered. If we discover things by accident that is good, too, since it saves research time and money that can be spent on other things. There is still so much out there waiting for us to find it in both the natural world and the lab.

@Fanburger I don't hate humanity. I just think we take credit for way too much and think ourselves superior. And I'm not the one disrespecting YOUR beliefs. I think all beliefs are valid in their own way. I never said I wanted to exterminate anyone. I never even said I hated anyone. Just because I have a different opinion from you doesn't mean I'm evil.

@CeliaVL Exactly my point

They better start munching!! There's a world of plastic out there.

Let's just hope terrorists don't figure out a way to weaponize this, as most products are made o fplastic.

Serendipity. Could be great. hmmm, I do have some concerns, mostly because I do not know enough. ie, what are the bi-products/wastes?

1

And then their employer patents it and refuses it's widespread use unless paid for it though they were funded by the gov't.....

I wonder if this will hinder the industry to wean itself off sustainable ways of making plastic PET bottles? It's nice to be able to digest it but it's still problematic to depend on fossil fuels to continue to make it in the first place.
Wonder what is the byproduct the enzyme makes?
Also, I hope there will not be any resistance to commercializing this enzyme that must be produced by using "GMO" (woooo...bad scary word) microorganism (most probably yeast, maybe e. coli)?

just saw that pass in my FB feed!
