    Last week, we achieved significant milestones in the lab, generating E. coli T7 electrocompetent cells and completing crucial experiments involving restriction enzyme digestion, gel purification, and ligation. Our metabolic modeling work showed potential growth without extra amino acids, with co-expression of the fucO and aldA genes playing a vital role in EG utilization. Additionally, we had a productive meeting with Solar Foods' Susanna Mäkinen and Juha-Pekka Pitkänen, discussing alternative food sources.
  • Week 28

    This week, the wet lab successfully conducted cloning tasks, including restriction enzyme digestion, gel purification, and ligation. Additionally, we recultured clones from pET-28a-MHETase Top10 and pET-28a-PETase Top10 and produced E. coli Top10 electrocompetent cells. In the dry lab, we focused on metabolic modeling, evaluating co-cultures, and exploring the co-expression of fucO and aldA. Stakeholder feedback was incorporated, and we reached out to the Chief Engineer in Waste Management at the Department of Environment in Bangladesh. Progress was made on blog posts and graphic design, including the creation of comic strips.
  • Week 29

    Last week, significant progress was made in both the wet and dry labs. In the wet lab, we successfully conducted electrotransformation of new vectors (pRSFDuet-1 and pET-28a) in Top10 cells and prepared media (LB and M9). Additionally, new FAST-PETase and MHETase inserts were ordered, and we designed fucO and aldA inserts for pRSFDuet-1. Translation rate issues were addressed, and protein folding on Puhti was set up, with SpyCatcher/SpyTag design optimization underway. In human practices, we had a productive meeting with stakeholders in Bangladesh. Graphic design also progressed, including the publication of a comic chapter, the completion of a brochure, the progress being made towards a project poster.

    We also had a valuable Zoom meeting with Ting Lu, receiving feedback on protein production and metabolic optimization for plastic degradation and bioconversion. He suggested bottleneck identification through HPLC analysis and conducting an adaptive lab evolution experiment.

  • Week 30

    In the dry lab, the team discussed the feasibility of SpyTag/SpyCatcher interaction with Sesilja Aranko. Initial findings suggest a moderate interaction strength for the construct. Further analysis will precede any order, with no rush.

    With a focus on R. opacus due to Stephen's recommendation and literature, we're aiming to propose a growth hypothesis related to a specific pathway for our project presentation.

    Conducting BLAST searches for the tph operon and tpaK in R. opacus DSM 43205, we folded relevant ORFs from hits.

    Shifting to the wet lab, R. opacus and C. testosteroni were cultured in EG, TPA, and TPA + EG conditions, both individually and together. Broths and microbial stocks were duly prepared.

    Lastly, we attended the iGEM Nordic Conference in Odense hosted by the SDU-Denmark iGEM team over the weekend.

August

  • Week 31

    In the Viikki lab, we prepared M9 medium with both EG and TPA, and both broth and agar for the plates. We cultured R. opacus and C. testosteroni with M9 + PET monomers and left them for overnight incubation. The following day when starting bioconversion, we noticed that after centrifugation, there were no pellets from the overnight culture. We decided to leave them in incubation for the duration of our upcoming trip. Our team had a great opportunity to attend Junior Jam - the European Meet-up conference in Münster hosted by the UniMünster iGEM team over the weekend.
  • Week 32

    This week, we were able to start bioconversion. Also, overnight culture of E.coli pSEVA-231 KanR was made and inserts IamB-MHETase-His-Stop and pelB-FAST-PETase-His-Stop were digested and ligated. In addition, we also did a transformation of pRSFDuet-1 with PETase and MHETase, and purified pSEVA-231.

    We investigated engineering MHETase in silico with MutCompute, which is a protein language model capable of giving predictions on potential residues to modify. The same model has also been used in recent literature concerning PETase variants.

    We had a meeting with this year’s KU Leuven iGEM team where we had a discussion related to the dry lab. We gave presentations about our project and iGEM at two different events. First we had a presentation at the Aalto Lab meeting where we were able to present our project to the people we had been working with. The second presentation was for the Finnish IBO team. We also got to know what IBO really is and after presentations we had some time to answer questions from high school students about iGEM and our fields of study.

  • Week 33

    In the wet lab, R. opacus and C. testosteroni were grown in laboratory evolution for the HPLC analysis. Insert digestion, gel purification and ligation had to be repeated. This step was repeated because the previous time the inserts were not cleaned and did not run in the gel. We did some troubleshooting and tried some minor protocol changes to make the protocol. After working, we did transformation, plating and restreaking from those transformation plates.

    Meanwhile in the dry lab, primers for PCR were designed and ordered. We predicted ddG and selected the top 10 most negative candidates. We also used AlphaFold and looked into docking. We started to go through our survey data and cleaned up the data.

    This week we started to record our promotional video and the voice-overs that we were going to use in it.

    We also had a meeting with Finnish plastic agency called Suomen Uusiomuovi Oy. It was a great opportunity to talk and learn about plastic recycling in Finland and also hear their thoughts about our project.

  • Week 34

    In the wet lab in Viikki, we got training for the use of HPLC, after which we got results from R. opacus and C. testosteroni bioconversion. The results were good for R. opacus but we decided to repeat the bioconversion to see if some modification could also give better results for C. testosteroni. We also received the PCR primers ordered previously and conducted PCR amplification of our PETase and MHETase inserts.

    The last biweekly newsletter for the summer was finished and sent out this week.

  • Week 35

    In the wet lab, we noticed that P. putida can grow on M9+30mM of TPA and M9+10gr/l of EG. We got good results from the transformation and were finally able to send our pRSFDuet-1 FAST-PETase construct for sequencing.

    We worked on our wiki texts and started to transfer our survey data into a graphical form.

    We shot the clips for our promotional video all over the Aalto campus. We got some good video footage and began editing the video.

    We also organized the first Heureka workshop with the ABOA team this week. We were able to teach visitors about DNA, RNA, proteins and the field of synthetic biology in general.

September

  • Week 36

    We received promising results from the Sanger sequencing by Eurofins Genomics. The sequencing quality was excellent, and for one of the colonies, there was a perfect match between both reads. In the case of the other colony, both reads showed a single silent mutation, but it is worth noting that this mutation occurred in a specific peak with a relatively low intensity. This week in the wet lab we started a plastic degradation test and enzyme purification.
  • Week 37

    The second Heureka workshop hosted together with the ABOA team was held this week. We introduced pipetting as a new element to the workshop, giving visitors hands-on experience on pipetting to a microplate. We had our meeting with the Science Basement and the ABOA team, during which we rehearsed and prepared for our upcoming presentation.
  • Week 38

    This week in the laboratory, we conducted Bradford protein assays on R. opacus bioconversion samples. We also took steps to prepare our samples for SDS-PAGE analysis.

    We gave two presentations, one for Master's students and one for Bachelor's students. We aimed to introduce iGEM and our project while looking for potential members for next year's team.

    This week, we also began to shift our focus toward writing wiki texts.

  • Week 39

    In the wet lab, we induced FAST-PETase expression by adding IPTG and attempted to confirm enzyme expression by SDS-PAGE analysis. Unfortunately, the result did not meet our expectations in terms of quality, so we decided to perform a second SDS-PAGE analysis.

    Additionally, on Saturday, we had the Science Basement talk in collaboration with the ABOA team at the Oodi Library in Helsinki.

    During our weekly meeting, we once again focused on wiki writing tasks and their deadlines.

October

  • Week 40

    We repeated the SDS-PAGE protocol, this time leaving it for two consecutive nights to destain. This time, the image of the gel showed some improvement. However, due to the absence of a control, we cannot definitively confirm that the observed band corresponds to our product.

    We also had another meeting with Nesli Sözer because we were finishing the experiments and we followed her advice on merging the two initial ideas, which were enzymatic plastic depolymerization and microbial protein production. We asked for her expertise in biotechnology and food production to discuss and refine our approach.

    This week, our goal was to complete all the wiki texts so that by the next week, they would be ready for publication on our wiki pages. After that our next step was to focus on the Grand Jamboree.

  • Week 41

    This week was spent on moving all of the completed texts to the wiki before the freeze on the 12th of october. Additionally, the registry pages were double-checked and finalized, and the attribution and judging forms were filled.
