I reckon I generally agree that it's very unlikely that mirror-bacteria would be viable in the wild!

This is covered in the article in 2 ways though: It says that some nutrients (like glycerol) are achiral - this might mean they could still find a food source in a regular-chirality world. It also mentions that the mirror-bacterial nonstandard-chirality might 'cloak' them from regular-chirality predators (or immune-systems).

I dunno, it does seem pretty far-fetched and I am not a professional scientist so I find it hard to evaluate the risk in any worthwhile way.. but I think it still seems worth considering?

I think regular microbiology would pretty quickly adapt to the mirrors. Evolution is crazy that way.

But multicellular organisms would be at a huge disadvantage. We don't have offspring every second, so adapting to the mirrors would be nearly impossible. They'd be able to cause havoc in plant and animal life that has mechanisms for dealing with regular bacteria.
