Ramirez M and Ambrona J (2008) Construction of sterile ime1Delta-transgenic Saccharomyces cerevisiae wine yeasts unable to disseminate in nature. Appl Environ Microbiol 74(7):2129-34
Abstract: The use of new transgenic yeasts in industry carries a potential environmental risk because their dispersal, introducing new artificial genetic combinations into nature, could have unpredictable consequences. This risk could be avoided by using sterile transgenic yeasts, unable to sporulate and mate with wild yeasts. These sterile yeasts would not survive the annual cyclic harvesting periods, being condemned to disappear in the wineries and vineyards in less than a year. We have constructed new ime1Delta wine yeasts, unable to sporulate and mate, and bearing easy to detect genetic markers, and which quickly disappeared in grape must fermentation just after sporulation of the yeast population. These sterile yeasts and maintained the same biotechnological properties as their parent yeasts, without any detectable deleterious effect of the ime1Delta mutation. They are therefore interesting biotechnologically for food industry applications and GMO environmental monitoring studies.
