We agreed, that the most active fraction contains 90 % laccase, which is commonly used in the literature.

These are the most active fractions we have chosen with their contained laccase amount:

*** ECOL: Fraction 50% 2 with a laccase concentration of 63,9 µg mL<sup>-1</sup>.
 +
*** BPUL: Fraction 50% 2 with a laccase concentration of 25,1 µg mL<sup>-1</sup>.
 +
*** BHAL: Fraction  5% 3 with a laccase concentration of 10,9 µg mL<sup>-1</sup>.
 +
*** TTHL: The best fraction of our TTHL laccase was fraction 50% 1 with a laccase concentration of 4,03 µg mL<sup>-1</sup>. In regard to Team Immobilization and Team Substrate Analysis we had to reach a higher amount of TTHL laccase. So we thought of combining two fractions. We chose the second best fraction of TTHL, which is 5% 3. To calculate the amount of contained laccase we had to compare the activity and reconsidered the slope. Since we stated the fraction with its highest activity as 90 % contained laccase, we calculated the amount of laccase regarding to that one. The following figure shows the slopes we got out of the activity from fraction 50% 1 and fraction 5% 3 (which is the second best). Accordingly to this, fraction 5% 3 contains 68,9% of laccase, which is 4,8 µg mL<sup>-1</sup>. In total, the composed fraction contains 4,4 µg mL<sup>-1</sup>.

    • After getting our interesting activity measurement results, we had to figure out which fraction is going to be used in the following experiments and how much laccase it contains besides other proteins. We agreed, that the most active fraction contains 90 % laccase, which is commonly used in the literature. Since we applied the same protein amount of each fraction for the activity measurements, we made sure that the results really correspond to the amount of laccase. These are the most active fractions we have chosen with their contained laccase amount:
      • ECOL: Fraction 50% 2 with a laccase concentration of 63,9 µg mL-1.
