* '''Team Wiki''': While using the labjournal more frequently there came up some questions.
+
-
** How detailed do we plan to write our labjournal entries?
+
-
** Do we want to write in keywords or explain everything in full sentences?
+
-
** Do we want to note every little detail about every successful or unsuccessful experiment or just the main important aspect?
+
-
We discussed, sighted some former iGEM team wikis and decided:
+
</div>
-
** each team is responsible for their own labjournal entries
+
</div>
-
** we divide our labjournal in weeks <span style="text-decoration: underline;">and</span> days to prevent it from looking to chaotic.
+
</html>
-
** the texts are supposed to state which team is writing, which experiment has been done and what the main aspects were. Also we will write about successful experiments, as well as problems and solutions we came up with. If possible links to protocols with further information shall be created.

* '''Team Modeling:''' Finding out, that the "normal" Michaelis-Menten kinetic isn't the right kinetic to model our situation, because therefor you need a high and stady state çoncentration of the subtrates. We have low concentrations and not really stady state. We found a transformed equation.

* '''Team Activity Tests''' and '''Team Immobilization''': After all this characterizing we feel so much closer to our ''T. versicolor'' laccase that its about time to make some activity test under immobilized conditions. So now we are cooperating with Team Immobilization. We have thought about many ways how to immobilize the laccase and decided to give Silica Beads the first try. Check the Immobilization Team´s protocol for further information. Our main problem was how to measure the samples with all those beads in it. Tecan will probably be confused and give us some false values due to the beads that are disturbing its laser. So we need a way to get the beads out (and thus also stop the reaction) at a very precise point of time. Centrifugation wasn´t an option because it would simply take too long and not stop the reaction exactly in the second we want. While checking the internet for solutions we found Multi-Well Membrane-Bottom Filter Plates. Those are supposed to work in a similar way then our regular plates which we used for the Tecan but furthermore those plates contain a membrane that sieve the liquids through the filter when centrifugated. Thus the beads are separated and the ABTS-Buffer solution can me analyzed at 420 nm for oxidized ABTS. The plates will need a while before they arrive here at the Cebitec, so we decided to first find out what the optimal amount of beads is and whether the beads might also bind ABTS (see labjournal Team Immobilization).

* '''Team Cultivation/Purification''': Starting our first cultivation Experiemnts with our first Biobricks. Transformes Cell are cultivated over night for our first preculture. After finishing our work in the laboratory we decided to collect some information for the best cultivation conditions. This night we find an interessting report of the Deutsche Bundesstiftung Umwelt (DBU) with interessting fact about different Laccases. With this Report we decided to screen different forms of th Erlenmeyer flasks.
