Several dozen people now presumably have Lumina in their mouths. Can we not simply crowdsource some assays of their saliva? I would chip money in to this. Key questions around ethanol levels, aldehyde levels, antibacterial levels, and whether the organism itself stays colonized at useful levels.
Any recommendations on how I should do that? You may assume that I know what a gas chromatograph is and what a Petri dish is and why you might want to use either or both of those for data collection, but not that I have any idea of how to most cost-effectively access either one as some rando who doesn't even have a MA in Chemistry.
