<p>In project design, we double our biosecurity through nutritional deficiencies and suicide genes. We used four deficiencies of yeast with four nutritional deficiencies as the engineered bacteria, and two different nutritional deficiencies remained after the transformation of plasmids. As a result, engineered yeasts can only survive under laboratory conditions at present, effectively preventing the leakage of engineered bacteria into the environment.
