- (a) device diagrams of wintergreen and banana generating devices.
- (b) smell test results from Jamboree
- File:IGEM06Smelltest.xls (xls)
- (c) smell test photo?
Figure 3
Autonomous wintergreen production
- (a) Device and parts level diagram of autonomous wintergreen synthesis
- (b) GC data of wintergreen total synthesis
- (c) GC data of J45120 without precursor
- (d) Pure methyl salicylate standard
Figure 4
Growth phase control
- (a) parts and device level depiction
- (b) growth-phase control of FP output
Figure 5
- (a) device diagram of regulated banana device
- (b) timecourse of banana smell
Figure S1
Restrospective project timeline. How long did each step take? [from this we can compute how we could do such work faster. We’ll want to work the pace of work into both the introduction and discussion].
Figure S2
- (a) GC data for IK cells versus normal E. coli;
- (b) mint scented bacteria with precursor versus TOP10 with precursor.
- (c) banana scented bacteria with precursor versus TOP10 with precursor.
