United KingdomJapanese researchers have developed a non-genetically modified yeast strain that naturally produces nine times more ornithine, an amino acid with potential health benefits. This breakthrough, achieved through traditional microbial breeding and molecular analysis, allows for the creation of functional craft beer without genetic modification. The yeast, derived from a wild Saccharomyces cerevisiae strain found on a university campus, was enhanced using chemical mutagenesis and selection techniques. Whole-genome sequencing identified a specific genetic mutation responsible for the increased ornithine production, which was confirmed to function across different industrial yeast backgrounds. The improved yeast maintains normal brewing performance, producing comparable carbon dioxide levels while secreting significantly more ornithine into the brewing medium.
