Default Re: [Build Advice] Model Anaerobic/Aerboic Breathing?

I'm not seeing anything that implies these creatures are photsynthesising.
The original post mentioned acetogenesis, which consumes H2 and CO2, though based on this I think both are intermediate steps in the process, not feedstock. In any case, such a metabolism would be (a) very slow, and (b) almost certainly poisoned by oxygen.
