Figure 1 Effect of EFE on cell growth. Cell density was measured at different time points to determine the effect of EFE expression. Cells were grown at 37 °C in LB until it was reached an OD of 0.6. The cells were then slitted in four samples of equal volume. Two samples were then induced with 5 mM Arabinose. Induced samples show a slowed growth rate, as espected (5mM arabinose is a strong induction that causes stress on cells). However, cell growth is not completely inhibited so EFE is not highly toxic

Figure 2 Ethylene detection through Micro GC. Cells were grown until O.D.600 reached 0.5. The cells were then splitted in two samples of equal volume (3 ml) and putted into an ermetically closed vial with a pierceable septum. One of the two sample was induced with 5 mM Arabinose. The vials were then putted into the thermoshaker for 4 hours. After that, the vials were connected to a micro GC and a measure was taken. Looking at the chromatograms, we can easily note that induce sample showed a characteristic peak corresponding to Ethylene (panel A). On the other hand, the not induce sample didn't show that peak (panel B). Panel C: picture of the vial connected to the micro GC.
