Contributions from Yuhan Sun, JNFLS 2019.

We added the reporter gene GFP to the downstream of the promoter, then detected the sensitivity and tolerance of the promoter to formaldehyde using BL21 as chassis. We cultured E.coli BL21 transformed with the plasmid （PfrmR-GFP）and added different concentration formaldehyde to different groups when the OD600 = 1, then we collected bacteria at certain time to measure the fluorescence and the absorbance. From the Fig. 1, we found that 0.8 mM formaldehyde is the best concentration for expression reporter protein GFP.
