Fluorescence microscopy of E. coli DH5α MCR and C. glutamicum ATCC 13032. The cells are carrying either the empty pEPR1 vector, pEPR1 containing the znr upstream region, or pEPR1 containing the znr-zur intergenic region. Images at a 400-fold magnification were taken with transmitted light or UV light at 395 nm to detect GFP fluorescence.
