TLDR
An attempt has been made to use low-voltage alternating current to kill microorganisms such as Escherichia coli using unalterable electrodes in the presence of chlorides in the medium.Abstract:
An attempt has been made to use low-voltage alternating current to kill microorganisms such as Escherichia coli. The bactericidal effect depends on the energy passing through the suspension and on the time during which the cells are left standing in the medium after the treatment. Most of the toxicity is due to an indirect effect developed with unalterable electrodes in the presence of chlorides in the medium. This method might be applied to eliminate pollution of natural waters.read more

Continuous-sterilization system that uses photosemiconductor powders.
TL;DR: A novel photochemical sterilization system in which Escherichia coli cells were sterilized with TiO2-immobilized acetylcellulose membrane reactor, a mercury lamp, and a masterflex pump, and it was found that this system was reusable.

Kinetics of sterilization of Lactobacillus brevis cells by the application of high voltage pulses
TL;DR: In comparison with existing steam sterilization technology, this new method of sterilization using relatively low temperature and short treatment time could prove to be an excellent method to minimize thermal denaturation of important nutrient components in liquid media.

TL;DR: Electrochemically injected silver from the anode is probably the instrumental agent, being effective in concentrations of about 5 μg/ml, which is the equivalent concentration of silver sulfadiazine that has been shown to give complete inhibition of bacteria, but without the sulfonamide moiety.

Inhibition of Cell Division in Escherichia coli by Electrolysis Products from a Platinum Electrode
TL;DR: In E. coli, the presence of certain group VIIIb transition metal compounds in concentrations of about 1–10 parts per million of the metal in the culture medium causes an inhibition of the cell division process, which implies that the growth process is not markedly affected.

Photoreactivation of ultraviolet-irradiated escherichia coli, with special reference to the dose-reduction principle and to ultraviolet-induced mutation.
TL;DR: The discovery of light-induced recovery (Kelner, 1949) and its confirmation for bacteriophage by Dulbecco (1949) gives fresh hope for solving the fundamental radiobiological problems of the lethal and mutagenic action of ultraviolet radiation.
