The discovery that CRISPR functions as an immune system to protect bacteria against viral infection was made at Danisco, a company looking to improve yogurt production. Rodolphe Barrangou tells the story of his discovery, which laid the groundwork for the gene editing revolution.
Rodolphe Barrangou studies beneficial microbes, focusing on the occurrence and diversity of lactic acid bacteria in fermented foods and as probiotics. Using functional genomics, he has focused on uncovering the genetic basis for health-promoting traits, including the ability to uptake and catabolize non-digestible carbohydrates. He spent 9 years at Danisco-DuPont, characterizing probiotics and starter cultures,… Continue Reading
