That is actually very cool and a much more promising path than animal cell culture, but tbh even with 10+ years of sustained investment I have serious doubts about whether it would compete with lower yielding sustainable ag efficiency at scale. Glad someone is doing the research though.
Seems like there is a two step conversion, step 1 is 40-50% efficient in mass conversion H + co2 to acetate by Clostridium ljungdahlii, then a 25% efficiency conversion by yeast to biomass. So that's already down to 2% overall for .07g/L/h at lab scale. Then additional losses in down stream processing to remove the water. The output is more of a yeast protien meat replacement.
