On this page we summarize the (successful) results and achievements of our teamwork.
Week 1: 2nd - 8th may
Bisphenol A:
- cloning of <partinfo>K123000</partinfo> and <partinfo>K123001</partinfo> behind weak (<partinfo>J23103</partinfo>) and medium strong (<partinfo>J23110</partinfo>) constitutive promoter (each part and both parts polycistronic)
- cloning of fusionprotein between <partinfo>K123000</partinfo> and <partinfo>K123001</partinfo>, also assembly behind weak and medium strong constitutive promoter
- testing and establishing of HPLC method for BPA detection
- expression of the successfully assembled BPA degrading BioBricks in E. coli TOP10
S-layer:
- successful PCR on the S-layer genes of Brevibacterium flavum and Corynebacterium crenatum
- successful cloning of the S-layer gene of B. flavum without TAT-sequence
Organizational:
- meeting with Bielefeld Marketing to discuss our participation at the science festival GENIALE in Bielefeld
Week 2: 9th - 15th may
Bisphenol A:
- assembly of <partinfo>K157011</partinfo> behind existing BPA degrading parts (for purification and testing of <partinfo>K123000</partinfo> and <partinfo>K123001</partinfo> in a cell free system)
- HPLC results: fusionprotein between <partinfo>K123000</partinfo> and <partinfo>K123001</partinfo> can degrade BPA and seems to work better than the polycistronic version (compare fig. 1)
S-layer:
- expression of the S-layer gene without TAT-sequence of B. flavum in E. coli KRX and BL21-Gold(DE3) after sequencing gave correct results
- successful PCR on the S-layer gene of Corynebacterium halotolerans
Organizational:
- moving to our own room in the CeBiTec
Week 3: 16th - 22nd may
Bisphenol A:
- successful PCR on the NADP oxidoreductase gene from E. coli TOP10
S-layer:
- successful cloning of the complete S-layer gene cspB of B. flavum, C. crenatum and C. halotolerans
- successful cloning of the S-layer genes of B. flavum and C. halotolerans without TAT-sequence, without lipid anchor and without both (only self-assembly domain)
Organizational:
Week 4: 23rd - 29th may
Bisphenol A:
- establishing a new method for analysis of BPA concentrations (extraction + LC-ESI-QTOF-MS)
S-layer:
Organizational:
- arrange a BBQ for our workgroup in the CeBiTec to get to know our coworkers
- substantiating our contribution to the GENIALE
Week 5: 30th may - 5th june
Bisphenol A:
- beginning of first characterization experiments for BPA degrading BioBricks (<partinfo>K123000</partinfo> and <partinfo>K123001</partinfo>)
S-layer:
Organizational:
- meeting with Prof. Alfred Pühler to plan our contribution to the CeBiTec symposium in july
Week 6: 6th - 12th june
Organizational:
- presentation of the iGEM competition at the 2nd BIO.NRW (PhD) Student Convention
Week 7: 13th - 19th june
Bisphenol A:
- cloning of NADP oxidoreductase in pJET1.2 finally successful -> waiting for sequencing results to remove illegal restriction sites
Week 8: 20th - 26th june
Organizational:
- finishing our first press release
- all devices (thermocycler etc.) and materials (competent cells, polymerase, kits) from our sponsors arrived
Week 9: 27th june - 3rd july
S-Layer:
- our synthesized S-Layers SgsE and SbpA finaly arrived
Week 10: 4th july - 10th july
Bisphenol A:
- analyzing the influence of temperature, promotor intensity and the characteristics of the fusion protein on BPA degradation
Organizational:
- presenting our posters from the teams of 2010 and 2011 at the congress Biotechnologie2020+ in Berlin hosted by the "Bundesministerium für Bildung und Forschung" (Federal Ministry of Education and Research).
Week 11: 11th july - 17th july
Bisphenol A / S-Layer:
- our BioBrick order (some fluorescences proteins and cleavage sites) from iGEM HQ arrived
Organizational:
