A growth experiment was set up, using M9 medium. In this experiment both the WT P. putida and P. putida containing the BBa_K1493000 BioBrick are grown in a 96-wells plate with 0, 15, 30, 45, 60 and 75µg/ml fusaric acid. Furthermore, DH5α E. coli cells (WT and BBa_K741002) were also grown in the same plate, but without fusaric acid. The transformed E. coli has a well characterized promoter with the same GFP gene downstream. By comparing the fluorescence of our fusaric acid induced promoter at different fusaric acid concentrations to this constitutive promoter, a characterization can be performed. |
