What I mean is if we skip three elements and see no growth we have no useful data. We have no idea what prevented growth. If we replicate someone else's work with the only difference being our bioreactor we at least know it wasn't the lack of a certain trace mineral that killed it. That seems like the fastest route to success.
We absolutely could attempt to copy any other HOB experiment. My preference for Pous et al, is that if we see no growth, Narcís will have a better chance of seeing where we went wrong & is more likely to be willing to take a look than someone who doesn't know us.
The closest of the three you have sourced may be the multi mineral veggie capsule as we have sodium and sulphate in our 'meso-nutrient' solution and we'd really rather avoid chlorine (as it will electrolyse to form bleach and kill the bugs). So if you add iron nickel and cobalt you at least should have all the elements they want. You then just need to hope that things like iodine and chromium aren't inhibitory and all the organics (which you wouldn't normally have in trace nutrients) don't mean that a non-HOB proliferates and makes one of the other nutrients rate limiting.
I'm wondering if a cheaper mineral pill, less bioavailable to humans (avoiding the organics), may be better for the HOBs. I tried enlisting AI:
Gemini hallucinated a few products that I couldn't find for sale anywhere, the ones it suggested that I could find seemed no better than those above.
Copilot gave me Sanatogen A-Z multivitamin & a fertiliser that it warned is not intended for human consumption.
As you have two pioreactors, a really useful experiment would be to run one as per Pous et al and run a second with your mineral capsules.
