  • prkA and ptac_Hneap
    • We tried to bring the prkA with RBS behind our construct ptac_Hneap but it was not successful.

  • prkA

  • ptac_glpX
    • We made a cultivation with our construct pSB1C3_ptac_glpX in xylose and glucose to see if there is a difference between the two media and also between induced and not induced. As a reference we used the E. coli wildtype. Because the culture in xylose did not grow we only could measure the OD600 of the glucose cultures. We used 30 ml in 250 ml flasks a 37°C and 250 rpm. The induction was with IPTG at on OD600 of 0.7. The cultivation lasted 12 hours. We made 2 biological and 2 technical replica for each culture. We took two samples (1 ml) of each biological replica for HPLC analysis that followed.

  • T7_Hneap

  • Proteinexpression of T7_Hneap induced with 0.5 mM IPTG.

  • ptac_Hneap

  • Proteinexpression of ptac_Hneap induced with 0.5 mM IPTG.
  • ptacglpX
    • We made a cultivation with our construct pSB1C3_ptac_glpX in xylose to see if there is a difference between this cultivation and the one with glucose and also between induced and not induced. As a reference we used the E. coli wildtype. We used 30 ml in 250 ml flasks a 37°C and 250 rpm. The induction was with IPTG at on OD600 of 0.7. The cultivation lasted 15 hours. We made 2 biological and 2 technical replica for each culture. We took two samples (1 ml) of each biological replica for HPLC analysis that followed.

  • T7_sap_csoS1-4_GFP and T7_csoS1-4_GFP
    • We tried to prove that the carboxysome we built can form the micro compartiment for the CO2 fixation. Therefore we measured the GFP fluorescence signal with the GloMax of Promega. We took 1 ml of the culture, washed it with 1 ml 1x PBS buffer and resuspend it in 600 µl 1x PBS buffer. For the measurement we used 200 µl for each technical replica in a 96 plate (black). The given protocol for GFP fluorescence was used.
      Additionally we examined the samples under a microscope.
