Interesting that this is led by the same Dr. Kate Adamala who ended the right-handed-proteins experiment a couple of years ago. Given how close she was I'm not surprised she's made this work.
in case you didn't know, your immune system WILL detect left handed pathogens, possibly more aggressively, and two of the body's mechanisms for fighting infection -- fever and ozonolysis -- are distinctly achiral
Arguably we should push for mirror life for industrial purposes FASTER because biocontrol is easier (they got nothing to eat) and lab escape is far less likely

They can eat fats, that are not chiral.
Perhaps they can eat some carbohidrates, all carbohidrates are chiral, but some bacterias may eat some of the unusual carbohidrates too. But amino acids are beyond any possibility, and fixating nitrogen is hard, so I also think they will starve to death very fast.
