>Usually these bioengineered yeasts need pretty specific growth conditions in order to eat
Until, say, they mutate independently. Now, I have no idea how likely that is, but I think the fear is not baseless. There's a fun SF book, "Directive 51", which explores this a bit. Not a bad book to cuddle up with.
Yeast drift a little but aren’t picking up new metabolic pathways very readily. Moreover these yeast don’t eat plastic they eat a component of PET in a bioreactor.
