Well, yes you’re correct, there are associated complexities I’ve glossed over. My point however is simply that all of these complexities only really need to be solved once by an expert or team of experts such that non-experts can then utilize such a biotechnology (“yeast strain”) to produce some medicinal compound or other useful engineered metabolite. A yeast strain that can’t be reliably cultivated by a non-expert with relative ease and safety (in a non-laboratory) wouldn’t make the cut, in theory. Also the same semi-synthetic organism could be applied in traditional pharmaceutical process settings as well, if for no reason other than cost reduction (and probably workforce reduction as well). So even “big pharma” has some incentive to contribute to this sort of technology.
