Engineering three strains Y. lipolytica that secrete each class of cellulase enzymes, thus allowing the yeast strains to use agricultural waste as a feedstock for growth and beta-carotene production.
Introducing the genes that will allow Y. lipolytica to produce thymol as an anti-helminthic agent for better intestinal absorption of vitamin A
Engineering mutual auxotrophy into the Y. lipolytica strains so they become dependent on each other and only survive within the bioreactor and not in the environment.
