' Cultured yeast ' has been developed by Boston 's Gingko laboratory . they coded yeast genes to determine which enzymes produce its smell . They are now experimenting with modifying the genome of yeast so that reactions within its microbes produce the same smell compounds . Experts are creating different strains of yeast to determine which ones work best . They are also sending samples to perfumers to make precise measurements .
