That’s the problem of unculturable species that pervades microbiology and anything related like agriculture. We have no idea what percentage of bacteria species can even survive long enough to be studied in the lab let alone industrialized. Even if someone manages to grow them accidentally, we’d never know it because if they don’t absorb any of the known stains, it’ll just look like agar on a plate under a microscope. Last I checked the “state of the art” was to use a freaking electron microscope and hope that the plating process didn’t destroy the sample.
