Achievements
We have fulfilled all bronze medal requirements, all the requirements for the silver medal and 3 of the 4 criteria for achieving a gold medal. Furthermore, we have qualified for 3 special prizes; Education and Public Engagement award, Software award, and Hardware award.
Medal Requirements
"Only those who attempt the absurd can achieve the impossible"
Albert Einstein
Bronze
✓ Register and attend
We registered for iGEM and had a great and educational (and sometimes frustrating) summer. We will also attended the Giant Jamboree.
✓ Deliverables
Yes, we met all the deliverables. Take a look around on our awesome Wiki. We have registered and submitted all our parts. We have filled out the safety, judging and registry forms as required. The team is ready with the presentation and poster for the Giant Jamboree.
✓ Attribution
Even though this project was driven and conducted by the team only, we have gotten a lot of much appreciated help during this project. Everyone should of course be credited for their attributions. Please see our attribution page.
✓ Part
We have registered and submitted our new part BBa_K2117003. This part encodes the human proinsulin peptide. The gene has been codon-optimized for the yeast Yarrowia lipolytica using a DTU-Denmark iGEM 2016 team designed codon-optimization tool that also considers illegal restriction sites.
Silver
✓ Validated Part
Our new BioBrick device BBa_K2117005 encodes the humanized Renilla reniformis green fluorescent protein (hrGFP) codon-optimized for Y. lipolytica and the translation elongation factor-1α (TEF1) promoter. We have used this device to demonstrate heterologous protein expression in Y. lipolytica and experimentally validated it through confocal laser scanning microscopy.
✓ Collaboration
We have helped different iGEM teams during the summer: Uppsala iGEM, UNIK_Copenhagen, SDU-Denmark. For more information please see our collaborations page.
✓ Human Practices
We sure went beyond the lab bench during this project. Our biggest achievement was the launch of the Biosensor project, a platform for allowing over 200 high schools nationwide to work with synthetic biology. We also held a meet-up for other iGEM teams, presented our project at different events and got media coverage. Please see our practices page for elaboration.
Gold
✓ Integrated Human Practices
Throughout our project we have been in close contact and collaboration with the industry. We started out searching for abundant waste streams in Denmark by contacting and visiting local factories, we then presented our idea to biotech manufacturing companies and all together the feedback made us more aware of the challenges our technology is facing. This ultimately led us to a more feasible product. Please see the Integrated practice page for elaboration.
✓ Improve a previous part
We have improved the two BioBricks; BBa_K530001 (crtE) and BBa_K530002 (crtI) created by the John Hopkins iGEM team 2011. We used site directed mutagenesis to successfully remove two illegal restriction sites and we furthermore improved the characterization. Please see the parts page for elaboration.
✓ Proof of concept
We successfully designed a functional plasmid (pSBB1A8YL) for transformation and replication in both Escherichia coli and Y. lipolytica. pSBB1A8YL is also compatible with the BioBrick standard by assembly with our own BioBrick device BBa_K2117005. This was proved by showing that we could utilize the construct in Y. lipolytica to express a heterologous protein, hrGFP. Please see the proof of concept page for elaboration.
✗ Demonstrate your work
We unfortunately did not have time to check our construct under simulated real-world conditions.
Special prizes
We have worked hard during the summer to obtain our goals. The results of our efforts are presented below.
Education and Public Engagement
The Biosensor project is an outstanding project, where kits for genetically modified organism (GMO) exercises are sent for free to all highschools in Denmark. The Biosensor kit contains everything needed for making 100 biosensors; deoxyribonucleic acid (DNA) with BioBricks from the iGEM registry, enzymes, antibiotics, buffers, ligases, cells and sterile equipment. The students can create biosensors by assembling a detection and response gene using 3A assembly to genetically modify E. coli. Until now GMO exercises have been unavailable for Danish highschools due to costs and law, but with the biosensor project it is no longer a problem. We tested the kit at a local highschool and raised almost 135,000 USD from both Danish and international sponsors and we expect the kit to be distributed by the end of this year. We hope it will inspire and encourage the next generation to work in the field of synthetic biology. Please see the Biosensor page
Software Tool
One of the numerous capabilities and features that iGEM is providing to current and future science disciplines and societies around the globe, is the ability of “building interdisciplinary bridges”. Therefore, the DTU BioBuilders team confidently believes that the developed TaiCO tool will bring wetlabs and computational biology a step closer to bidirectional understanding. This tool is a stand-alone cross-platform software developed in Python (using only standard libraries) and provides comprehensive codon optimization of DNA sequences from protein sequences. Its uniqueness lies in the fact that the researcher can specify the organism and the desired protein sequences to optimize according to the tRNA adaptation index (TAI) for the specified organism. This is novel in terms of codon optimization methods approach is framed by a user friendly GUI along with the option of removal of desired restriction sites from the resulting DNA sequences. Please see the codon optimization page for elaboration.
Hardware
When taking your synbio project to real applications, fast growth is crucial for the viability. The optical density is commonly used as a proximation for cell count and numerous instructions for DIY spectrophotometers exist. However, in order to estimate growth rates, cultures must be sampled over a long period of time. During our project, this was done by a robot handling microtiter plates. We are aware that this is a technology not everybody has access to. Therefore, we took the concept of a DIY spectrophotometer and expanded it to a platform that carries out small scale fermentations comparing growth of your modifed strain to a wild type or other organisms. To take it even further, we encapsuled it in a compact housing that fits on any lab bench. It can be rebuild or modified by anyone with access to a PC, a 3D-printer and a laser cutter. Please see the microfermentation platform page for elaboration.
Milestones

JulyColor proteins encoded in pSB1A8YL was successfully expressed in E. coli!
JulyAfter 10 weeks of trial and error, a transformation protocol compliant with Y. lipolytica was obtained. Making this yeast engineerable is getting closer!
AugustOur goal to fund the project with 60,000 USD was way over achieved, when the final funding totaled at 120,000 USD! Now we can start buying equipment for our own DTU iGEM lab for future teams.
AugustGetting rid of the breadboards! The DIY microfermentation platform has been finally fit into the housing using the printed circuit board we designed.
SeptemberGenome scale modeling is coming along. We achieved getting the same PHPP values for growth rate changes in E. coli when varying oxygen and nutrient uptake rates, as in published papers.
SeptemberOur DIY lab is coming along, with the first growth curve measured with the final prototype of our microfermentation platform.
