"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." A strain with modifications 1 and 2 was found. 3 and 4 were added to it. This means we could check for mutacin-1140 health issues by tracking those people but not the increased alcohol in blood. https://www.astralcodexten.com/p/defying-cavity-lantern-bioworks-faq https://www.astralcodexten.com/p/defying-cavity-lantern-biow...
