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 [http://en.wikipedia.org/wiki/Bisphenol_A BPA] detection
- expression of the successfully assembled BPA degrading BioBricks in E. coli [http://openwetware.org/wiki/E._coli_genotypes#TOP10_.28Invitrogen.29 TOP10]
S-layer:
- successful PCR on the S-layer genes of [http://expasy.org/sprot/hamap/CORGL.html Brevibacterium flavum] and Corynebacterium crenatum
- successful cloning of the S-layer gene of B. flavum without TAT-sequence
Organizational:
- meeting with [http://www.bielefeld-marketing.de/de/index.html Bielefeld Marketing] to discuss our participation at the science festival [http://www.geniale-bielefeld.de/ 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 [http://www.promega.com/products/cloning-and-dna-markers/cloning-tools-and-competent-cells/bacterial-strains-and-competent-cells/single-step-_krx_-competent-cells/ KRX] and [http://openwetware.org/wiki/E._coli_genotypes#BL21.28DE3.29 BL21-Gold(DE3)] after sequencing gave correct results
- successful PCR on the S-layer gene of [http://ijs.sgmjournals.org/cgi/content/abstract/54/3/779 Corynebacterium halotolerans]
Organizational:
- moving to our own room in the [http://www.cebitec.uni-bielefeld.de/ CeBiTec]
Week 3: 16th - 22nd may
Bisphenol A:
- successful PCR on the [http://www.brenda-enzymes.org/php/result_flat.php4?ecno=1.18.1.2 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. [http://de.wikipedia.org/wiki/Alfred_Pühler Alfred Pühler] to plan our contribution to the [http://www.cebitec.uni-bielefeld.de/content/view/209/88/ CeBiTec symposium] in july
Week 6: 6th - 12th june
Organizational:
- presentation of the iGEM competition at the [http://www.bio.nrw.de/studentconvention 2nd BIO.NRW (PhD) Student Convention]
Week 7: 13th - 19th june
Bisphenol A:
- cloning of NADP oxidoreductase in [http://www.bioinfo.pte.hu/f2/pict_f2/pJETmap.pdf pJET1.2] finally successful -> waiting for sequencing results to remove illegal restriction sites
Week 8: 20th - 26th june
Organizational:
- finishing our first press release
