what the plastic is made of. so any molecule that contains C, H (and atoms like O and S F or N depending on the type of plastic) can be synthesized by plastic eating bacteria. so we can also make oil and fuel from it
Metabolism can definitely create useful products. Alcohol is formed from yeast metabolising sugars, for example. Same with miso paste. Hell, we can make milk without cows now via precise fermantation.
This is so great and so bad at the same time. We're gonna have to go back to using tar and shit for things we actually want to last. That's not going to be cheap...
I mean, wood already biodegrades quite readily, yet we are able to make some pretty long lasting things out of it anyway. Having a bacteria that can break down some variety of plastic doesn't really imply that all plastic things are going to rot away like old fruit.
