Episode 404 - Ants , Acid, and Yeast that grow acid

Ants, acid and yeast that can grow their own acid. Ants use formic acid to keep their colony safe inside and out. By ingesting formic acid, Ants are able to ward off dangerous pathogens. Passing food with your mouth isn't very socially distant, but ants eat acid to make it safe. How can yeast be used to 'grow' materials needed to make perfume and dyes? Succinic acid is a useful chemical precursor, but its possible to grow yeast that are able yo produce on scale as a by product. Finding just the right genes with CRISPR and super computers can turn yeast into a chemical production powerhouse.
