Microorganism model, Escherichia coli

Matsunaga et al. studied the disinfection of drinking water at room temperature using Escherichia coli as a model microorganism. As shown in Fig. 7, the carbon cloth electrodes were interwoven with ion exchange membranes and rolled around a glass tube [32]. At an applied potential of 0.7 V vs. SCE, an initial cell suspension of 10 cells/dm was reduced to <10 cells/dm at a residence time of 10 min. The disinfection was thought to be based on the electrochemical oxidation of intracellular coenzyme A.
