Aims for the Project
- Engineer strains of E. coli for PLA synthesis
- Develop bioassay to screen PLA production
- Apply MAGE to optimize PLA production, guided by FBA
- Introduce type 1 secretion system to export and extract PLA
- Make a bioplastic
Introduce type 1 secretion system to export and extract PLA
- We needed a way to export the PLA once it was synthesized by the E. coli
- We found the paper by Linton 2010 where she focused on exporting PHA from engineered E. coli
- She used Phasin, a PHA granule associated protein that plays a role in granule formation, with a hlyA tag.
- This allowed the cells to export the PLA since the hlyA tag was attached to the granule

- Due to the similarity between PHA granules and PLA granules we hypothesized that this same export system would allow us to export PLA from our cells.
