but before starting, rodolphe added a twist. he used crispr technology to enhance the bacteria used in the fermentation of milk. - we used it to build resistance in bacteria that make cheese and yogurt, to have better fermentations d better manufacturing of dairy products. - [kondwani] by vaccinating thbacteria, his dairy ltures almost aays succd which improves the process of making yogurt and cheese. processes like these, also make them healthier. - crispr has been a life changer and then also haopened tremendous avenues to provide a healthier and more sustainable food supply for humanity. - [kondwani] but the true revolutionary potential of crispr technology is just now starting to be realized. - other people caught on to using these molecular machines to actually cut dna, to do genome editing, not just in bacteria but in other organisms. by understanding what crispr is and how it works, scientists were able toevelop technologies to enable us to now change the world. - [kondwani] by 2050, the world population is expected to so
