OVERVIEW
The following page describes the summarized results of our work in each of our subprojects. Please visit the corresponding links to the subproject specific pages to get more details on the background information and our methods.
ENGINEERING SUCCESS
Cellulase Integration
Go to Cellulase page
In order to provide a sustainable, community-based solution, we plan to genetically modify Rhodosporidium toruloides, an oleaginous yeast that naturally produces beta-carotene and lipids, to be more robust and resource-efficient. By modifying the yeast to produce cellulase, it can then use common agricultural waste products as an energy source for synthesizing its oil. It can then be eaten as a vitamin A supplement. The yeast strain, while naturally safe and non-pathogenic, will also be genetically modified to include a kill switch for bio-containment, and optimized for oil production.
Biocontainment
Go to Biocontainment page
We developed a sustainable and affordable biosafety system where two yeast strains will be co-cultured together in a syntrophic community. These strains will each be auxotrophic for a molecule the other strain has been modified to overproduce. This ensures that the two strains are co-dependent, reducing the chances of environmental escape. The organism can only proliferate if both strains are present in sufficient quantities to support each other’s growth. Ultimately, this novel method of co-dependent auxotrophy provides an easily implementable biocontainment strategy to prevent the escape of genetically engineered organisms.
This season specifically, we developed a proof of concept for our co-culturing system using a pair of already engineered S. cerevisiae strains. We are happy to say that by the end of this season, we accomplished quite a bit:
✔ We successfully characterised a proof of concept for our biocontainment system using a pair of already engineered S. cerevisiae strains:
- Characterised the strains in terms of auxotrophy and amino acid overproduction
- Created a viable co-culture demonstrating the ability of the strains to survive using the amino acid released by each of the complementary strains
- Demonstrated the inability of the yeast to survive in environmental conditions outside of the expected growth vessel conditions
✔ We designed and submitted a total of eight parts to the parts registry that allow for the engineering of Y. lipolytica to create complementary overproducing, auxotrophic strains.
