Project description

This summer, MIT's iGEM 2006 team engineered Escherichia coli to produce a wintergreen scent during exponential phase and a banana scent during stationary phase using only endogenous metabolites. Thus, our project demonstrates that

  1. It is indeed possible to design, build and test a synthetic biological system over the course of a summer.
  2. Biosynthetic devices that produce scented compounds can be successfully engineered in E. coli.
  3. Biosynthetic devices can be purposefully regulated via transcription based control devices.

Motivations

Our project focused on engineering Escherichia coli to produce different compounds that smell fragrant. Since scents can both act as natural reporters and have a diverse array of applications, they represent a promising but thus far unexplored area of synthetic biology.

Future applications of this work that we envision include ...

  • Improving the workplace environment for microbiologists working with Escherichia coli since E. coli produce a natural foul scent.
  • Porting our system to bacterial species involved in bioremediation.
  • Implementing our system in bacteria responsible for bad human odor in the mouth, armpits and feet.

Contributions

Devices

  1. A biosynthetic device that converts salicylic acid to methyl salicylate (or wintergreen).
  2. A biosynthetic device that converts isoamyl alcohol to isoamyl acetate (or banana smell).
  3. A PoPS source that is only active during stationary phase.
  4. A PoPS source that is only active during exponential phase.

Systems

  1. Escherichia coli capable of producing a wintergreen scent autonomously (without addition of any precursors).
  2. E. coli capable of producing a banana scent autonomously (without addition of any precursors).

Future work

In the future, we envision doing the following ...

  1. Porting the biosynthetic device that synthesizes isoamyl acetate to yeast to make banana bread.
  2. Porting the biosynthetic device that synthesizes methyl salicylate to Pseudomonas fluorescens, a species commonly used in bioremediation.
  3. Carrying out more extensive, quantitative characterization of our biosynthetic devices using gas chromatography.
