Week 11 (07/09 - 07/15/12)

Monday July 9th

• Team Student Academy: This week the Student Academy took place. Today we held a presentation about the background of our experiments and answered all the questions the pupils had. Furthermore two of us participated at the an unconstrained meeting between the instructors and the pupils in the evening.

Tuesday July 10th

• Team Site Directed Mutagenesis: Generated the first Site-Directed-Mutagenesis primer for Bacillus pumilus (two sites), Xanthomonas Campestris (two sites), Escherichia coli (one site)und Thermus thermophilus (one site).
• Team Cellulose Binding Domain: Searched NCBI for Cellulose, Chitin & Keratin binding motifs in accessible organisms; found two Chitin-binding-domains in Bacillus halodurans
• Team Student Academy: The experiments were performed by one half of the pupils in groups of 2-3. Afterwards we held a presentation about the iGEM competition, the project of the last two teams from Bielefeld and about our project. In the evening we had a barbecue with the pupils and the iGEM team with a lot of interesting discussions.

• Team Fungal Laccases: We got the sequences for five different fungal laccases from the requested plasmids on Monday 2nd and they wanted to send us plasmids with the laccase ORFs on it. The laccases are Tv5, Tv10, Tv13 and Tv20 from Trametes versicolor and Pc35 from Pycnoporus cinnabarinus. We designed primer pairs with prefix and suffix overhanging ends for cloning in pSB1C3 and a primer pair for cloning in shuttle vector.

Wednesday July 11th

• Team Cellulose Binding Domain: Looked up the sequence of Clostridium cellulovorans cellulose binding protein gene (cbp A) http://www.ncbi.nlm.nih.gov/nuccore/M73817 made a Clonemanagerfile and protein-BLASTed the sequence to find out the domain of the Cellulose-Binding-Domain: 103bp-378bp
• Team Student Academy: The experiments were performed by the second half of the pupils and the groups from yesterday analyzed their plates.
• Team Bacterial Laccases: We made glycerin cultures of the finished biobricks.

Thursday July 12th

Friday July 13th

• Team Student Academy: The groups from Wednesday analyzed their plates. Together with the pupils we made a final analysis of the results, discussed about all problems and questions and helped with the preparation of a presentation, they had to hold in front of all instructors and participants.

• Team Bacterial Laccases: We got new Streptomyces DNA from or supervisor C. Rueckert. He did an alignment with our S. griseus and S. lavendulae sequences against a local database for Streptomyces and identified S. rosechromogenes, S. tue and S.goe. Those laccase genes showed simularity to our laccase genes. Since he had isolated chromosomal DNA we were able to work with them. We set the PCR with the three Streptomyces. On this PCR S. tue DNA could be amplified, but it wasn't specific for that what we expected. No products could be amplified on the other two.
