Comment Comment by _--__--__ I'm skeptical as well but from the earlier linked faq (https://www.astralcodexten.com/p/defying-cavity-lantern-biow...):>BCS3-L1 has four main genetic modifications:It produces a weak antibiotic, mutacin-1140, which kills competing oral bacteria.It’s immune to mutacin-1140, so it doesn’t kill itself.It metabolizes sugar through a different chemical pathway that ends in alcohol instead of lactic acid.It lacks a peptide that its species usually uses to arrange gene transfers with other bacteria. parent _--__--__ 9 months ago
>BCS3-L1 has four main genetic modifications:
It produces a weak antibiotic, mutacin-1140, which kills competing oral bacteria.
It’s immune to mutacin-1140, so it doesn’t kill itself.
It metabolizes sugar through a different chemical pathway that ends in alcohol instead of lactic acid.
It lacks a peptide that its species usually uses to arrange gene transfers with other bacteria.
