Week 13 (07/23 - 07/29/12)
Monday July 23rd
- Some of our team members were at CAS conference in Munich from 07/23 - 07/25/12.
- Successful PCRs of laccase gene lac5 from Trametes versicolor with plasmid DNA from Uni Greifswald as template.
Tuesday July 24th
- Team Activity Tests: Today was the moment of truth. We received the first recombinant laccases from the cultivation team. We started with testing the supernatant from the cultivated cells to check whether they secrete laccase. We added 0,1 mM ABTS in each well that was filled with supernatant from Escherichia coli, Bacillus pumilus, Bacillus halodurans C-125, Xanthomonas campestris pv. campestris B100 and E. coli KRX (negative control - cells without plasmid) and measured as usual. There was no change in the OD so that we assume that no secretion takes place. Afterwards we tested potential laccase activity by filling each well with laccase and buffer (check protocols to see which buffer we used) and added 0,1 mM ABTS. Unfortunately no activity was seen. We will try again soon.
Wednesday July 25th
Thursday July 26th
- Team Modeling and Team Sponsoring: meeting Mr. ??? from the clarification plant of Schloß Holte and finding a new cooperation partner. He want to give us the information we need to equate our model and design our cleaner. On top he wants to ask if the clarification plant can sponsor our project.
Friday July 27th
Saturday July 28th
- Team Activity Tests: See, we are back already! Today we received different samples from Escherichia coli, Bacillus pumilus, Bacillus halodurans C-125, Thermus thermophilus, Xanthomonas campestris pv. campestris B100 and E. coli KRX (negative control - cells without plasmid). The cells were all cultivated at 30°C and supplied with copper. We tested each one of them but none of them showed laccase activity.
