The Research of Novel Electrolyzed Water Spray to Eradicate Bacteria E-coli and an Attenuated Human Flu Virus

In this study, water including tap water, pure water and salt water, and an apparatus for producing electrolyzed water were used to generate an electrolyzed water mist spray or spray. This instantly generated electrolyzed water mist spray or spray has oxidation-reduction potential（ORP）≥1200mv,and contains non-specific total oxidation capacity which equals to 0.28±0.10ppm,0.06±0.04ppm and 3.92±0.39ppm of dissolved ozone. This instantly generated electrolyzed water mist spray or spray does not release detectable ≥0.1mg/m3 of gaseous ozone. This instantly generated electrolyzed water mist spray or spray has pH 8.4±0.4 and releases negative air ion. The apparatus for producing electrolyzed water has a positive electrode which is covered by a conductive diamond material (Patent# CN215308550U).

In this study, we hypothesize that the instantly generated electrolyzed water mist spray or spray relieves skin and mucosal inflammation including the itches through indirect actions by killing microbials and reducing endotoxin level and direct action by serving as an inflammatory inhibitor.

Detection of residual E. coli in the collected water samples. 1 ml of the collected water sample is inoculated on the surface of the solid LB agar plates and cultured overnight at 37°C in an incubator. Calculate the total number of bacterial colonies as CFU. In other words, the total number of bacteria/ml inoculated water sample (CFU) is the number of colonies formed on the surface of the plate. It is assumed that the bacteria on the hands are mostly washed out into the drain water sample pool and that the left over bacteria on the hand after rinsing is negligible. The leftover also can be measured by pressing the rinsed hand after on a large LB agar plate and then count the colonies (unstained and stained) after overnight incubation at 37°C.

Detection of residual human influenza virus H1N1 titers in the collected water samples. Viral titer (TCID50) is used to measure the infection of the dosage of 50% MDCK cells. MDCK cells were inoculated into 96-well plates at 1.0×104 cells per well and cultured overnight at 37°C in a cell culture incubator. We wash the hands and collect the drained water for the titer measurement. 100 ul of the water sample after the multiple proportion dilutions is inoculated into 96-well plates which contain overnight cultured MDCK cells. After 3 days of incubation at 37°C, TCID50 was calculated using the Reed and Muench method. 1 plaque forming unit (PFU) is equal to 1 alive virus particle.
