Figure 9. . Production of iodine (measured as blue starch complex).

Figure 9. 

Wells contained 50-μM tetracyclines, 400-mM KI, with and without 50-mM azide, excited by 10 J/cm2 of UV A or blue light. Aliquots were removed, added to starch indicator and absorbance read at 600 nm.

DMCT: Demeclocycline; DOTC: Doxycycline; UVA: Ultraviolet light.
