Plastic eating bacteria could change the world.

An animal called a quoll thought to be extinct for 130 years has been rediscovered.
That’s a significant step forward from when the last time I read up on the plastic eating bacteria. Granted, I’d prefer it if it was recycled into something other than more plastic… but I’ll still take it.
I think it's highly likely there's a catch, like you have to grow 250 tons of bacteria. Usually there is with amazing advances which get a news story but not a lot of reaction from other academics.
They’re still in the process of genetically engineering the bacteria, so their efficiency is still a work in progress.
There’s also the issue that economies of scale tip heavily in plastics direction,
It’s not a carbon neutral process. There’s significant both heating and cooling involved.
And, it doesn’t really solve the issue of retiring plastics.
The last update I read on the bacteria, prior to the genetic engineering, mentioned that the bacteria didn’t actually like the plastic and would only really break it down for want of something more practical. Presumably that has been solved, but I didn’t see it brought up in the article.
This feels like an ice 9 situation
Well, how would we change it from plastic into something else?
The article explains that they use the bacteria to basically break down the plastic into two solutions, which they ultimately recombine into plastic—seemingly out of lack of any other practical use for the results.
I’m not a scientist, I don’t know what could be a better use for the results of the bacteria doing their job. And seemingly, neither do the scientists, but it’s still a very young project in the grand scheme of things.
Don't worry, we'll invent a type of plastic immune to this bacteria and start the whole process anew!
As an aside, 'plastic eating bacteria' have been 'discovered' countless times over the past several decades.
Possibly due to each discovery being some bacteria that eat exactly 1 chemistry of plastic.
: )
No idea about that, but your bringing up the issue reminded me of the movie Andromeda Strain...
"Just as he has this insight, the organism mutates into a non-lethal form that degrades synthetic rubber and plastic"
Apparently there's a TV show based on the same story.
That Vanity Fair story is one of the craziest things I’ve ever read, thanks for sharing!
Isn't that bonkers? I read it twice I was so interested.
Nice! As a follow up, is there a good app/source to get more positive articles Ike this regularly?

I tend to read Metafilter (https://www.metafilter.com/), it's not all good news but it's a weblog of really interesting content.
The quoll species in question (it is a small doglike marsupial, a carnivore, and very cute) was known to be alive and well in Queensland (a state to the north) and was only extinct in South Australia. It seems to have spread back to the southern state.
There are other species of quoll.
Oh ok sorry. Still interesting though!
Yes, very. Did the rounds for a week or more here in Oz. Interesting that it hit the world news though. It's just another native cat, to most Aussies.
Australia must be so interesting because of all the animals. Although I'm given to understand that some are pretty deadly.
Nah, if you live in town you see few, and if you live in the country you just know not to poke the snake or spiders. People who mess with them get hurt, but people who leave them alone see them safely, and then the animals run away. It is played up for laughs, but it's really safe as houses.
We don't have rabies here, so no rabid dog dangers. No moose or bears. It is good to see a wombat or a kookaburra, but not dangerous unless you try to feed them.
My husband has Australian parents, we live in Canada, and he has pictures from his childhood visits of him petting a kangaroo, which seems wildly dangerous as I think it could kick the crap out of you!
**No different to peting a deer. They can be tamer, like deer at a petting zoo park. Most people don't tame the boomers: If he is a kid, it is likely a joey (juvenile) or a wallaby(smaller species) and likely at an animal park petting zoo. If the roo is taller than a grown man then rare but not impossible tamed red kangaroo boomer and not during rut. Deer can be just as dangerous.
Incidentally, roos taste similar to venison too. Good healthy lean meat, better for the environment here than hoofed animals, which cut up the ground and damage the native plants.**
