I'm the creative director at Ginkgo (YC S14), the company featured in this article, and I'm happy to answer any questions people have about biological design.
Thanks Christina, seems a really interesting field.
I wonder for example what happens with the doses. How do you protect yourselves from your biological organisms designed to make complex substances in, maybe, I'm just guessing, concentrated doses?. Substances that could lead to allergic reactions, like Artemisin does in some cases, for example.
In the case of artemisinin and with all the cultured ingredients we are making like the fragrances mentioned in the article, the product is extracted from the yeast so it would work just like any other medicine or ingredient when it comes to dosing or formulation.
