Abstract
- Escherichia coli JM101 cells were subjected to pore-forming electric fields, irradiation with ultraviolet light or oxidative stress by either the lipoxygenase products 9- and 13-hydroperoxyoctadecadienoic acids (9- and 13-HPOD) or hydrogen peroxide. It was found that all chemico-physical stresses enhanced ultraweak light emission from the bacterial cells, the most effective treatment being electroporation (up to 20-fold increase in luminescence compared to the control value), followed by oxidative stress with 9- or 13-HPOD (up to 4-fold increase) and irradiation with UV light (up to 2.8-fold increase). Bacterial luminescence was always in the red edge of the spectrum and was paralleled by changes in membrane oxidative index and specific activity of catalase and superoxide dismutase. © 1998 John Wiley & Sons, Ltd.
