“…As previously mentioned above, EW is only produced from NaCl and tap water and reverts to regular water after use [ 77 ]. Second, EW has a broad-spectrum inactivation ability and rapid antibacterial activity, which possesses nonselective properties [ 78 , 79 ]. HOCl was produced by an enzyme called myeloperoxidase, which uses hydrogen peroxide (H 2 O 2 ) in our body as a substrate to react with neutrophils.…”

As the situation of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) is still deteriorating, there has been a huge increase in the demand and use of disinfectants. Electrolyzed water (EW), as a novel broad-spectrum disinfectant and cleaner, has been widely used for several years. EW can be produced in an electrolysis chamber which contains dilute salt and tap water. It is an effective antimicrobial and antibiofilm agent, with several advantages such as on-the-spot, cheap, environmentally friendly and safe for human beings. Therefore, EW holds potential significance for high-risk settings in hospitals and other clinical facilities. EW can also be applied for wound healing, advanced tissue care, and dental clinics. The present review article highlights the latest developments and new perspectives of EW, especially in clinical fields. Furthermore, the main action modes of antibiofilm and antimicrobial will be summarized.

“… Kim et al (2019) reported that SAEW (pH: 6, ACC: 20) can efficiently inactivate E. coli O157:H7 , S. aureus , Salmonella enteritidis, and B. cereus with 10-min treatments. Al-Qadiri et al (2019) also reported that the extent of reduction was 1.53 log CFU/mL for B. cereus and 1.8 log CFU/mL for C. perfringens after 1 min of treatment at 60 ppm, respectively. The main reason might be that most chemicals are limited to penetrate into the cytoplasm of spore-forming bacteria, which may provide an initial barrier for the penetration of active ingredients (disruption of cell membrane and denaturation of other organic macromolecules) ( Kim et al, 2000 ).…”

Slightly acidic electrolyzed water (SAEW) has been recently proposed as a novel promising sanitizer and cleaner in the agricultural and food industries. However, several factors, including water hardness, were considered to strongly affect the physical properties and sanitization efficacy of SAEW. To study the effect of water hardness on the SAEW production, we evaluated the production properties and sanitization effect of SAEW, which was generated from water sources in 16 representatively geographical locations of South Korea. The results showed that the hardness of water sources from Kangwon-do, Jeollanam-do, and Daegu was 22–41 ppm; that from Busan, Gyeongnam-do, Gwangju Bukgu was 80–443 ppm, and that from seven other locations was 41–79 ppm. SAEW is produced from water hardness less than 50 ppm and greater than 80 ppm was beyond the accepted pH range (5.0–6.5). Notably, high-hardness water (>80 ppm) containing 5% HCl could be used to produce SAEW with accepted pH. The SAEW generated from low-hardness water with additions of 2% HCl and 2 M NaCl at 7 A showed accepted pH and higher germicidal effect. Furthermore, SAEW with the available chlorine concentration of 27–41 mg/L for 1 min was sufficient to completely inactivate non–spore-forming foodborne pathogens. Sanitization efficacy was not markedly affected by storage conditions for SAEW at 40 ppm. Our results demonstrated that the degree of water hardness is an important factor in the production of SAEW, which would provide a foundation for commercial application of SAEW.

“…The combination of natural oxygenated water with HOCl increase the oxidation reduction potential, prove the low pH and concentration of available free chlorine in the form of molecular chlorine or hypocholorous acid. The properties of natural oxygenated water that has broad spectrum inactivation ability and rapid antibacterial properties which possess nonselective properties [54,55,56]. Electrolyzed oxygenated water possessed strong antifungal activities against Aspergillus flavus conidia and mycelia [57].…”

The use of synthetic fungicide are affecting the health, disturbing the ecosystem of the environment and has develop resistance of many pathogenic fungi. This study aimed to investigate the antifungal activity of ethanolic Piper betel (P. betel) crude leaf extracts with HOCl formulated by natural oxygenated water against selected crop pathogenic fungi which are Fusarium spp. and Phakopsora euvitis fungi. The screening test was done using well diffusion technique where the parameter observed was the Percentage Inhibition Radial Growth (PIRG). The antifungal effects of P.betel crude leaf extract with formulated HOCl minimum inhibitory concentration (MIC) were further evaluated by micro broth dilution method and minimum fungicidal concentration (MFC) were tested by agar well method. Screening results showed the P.betel extracts with HOCl have potential to inhibit the fungi radial growth when compared to positive control Kencozeb M45. MIC and MFC results portrayed the extracts with formulated HOCl displayed fungicidal activity against both fungi in the range of 2500 µg/ml until 5000 µg/ml for Fusarium spp and Phapkopsora euvitis, respectively. To the best of our knowledge this is the only natural oxygenated water source in Malaysia and first reported with combination of Piper betel extract.
