The virucidal activity of 8 disinfectants was analyzed towards 3 groups of viruses responsible for diseases in animals (pneumovirus, coronavirus, parvovirus). Whether organic matter is present or not, parvoviruses are the most resistant, since concentrations of disinfectants 20-500 times higher than …

{Includes Sodium Chlorite} 1988. Virucidal efficacy of chemical disinfectants, heating and ultraviolet radiation against mouse hepatitis virus (MHV), canine coronavirus (CCV), Kilham rat virus (KRV) and canine parvovirus (CPV) were examined. Coronaviruses (MHV and CCV) were inactivated by ethanol, isopropanol, benzalkonium chloride …

Not all biocides present the same efficacy against viruses, with ethanol being poorly efficient and heat as well as sodium hypochlorite presenting limited efficacy depending on conditions tested. In our experiments, tested bio-cides containing peracetic acid presented very good overall virucidal efficacy; however, observed differences in susceptibility of different parvovirus species should be taken into account. Atmos-pheric decontamination with VHP presented good effica-cy against all tested viruses including parvoviruses even in the presence of blood. In general, this type of technol-ogy is used following pre-cleaning, although it has been shown to be very effective even under grossly soiled con-ditions

"“In our research, we showed that, by using our existing proprietary process, we can indeed generate CLO2 economically and without using chemicals.” CLO2 is used by the industry as a pretreatment step to break the oil/grease emulsions, destroy chemical additives, and to kill bacteria. CLO2 generation infrastructure is capital-intensive and results in high consumables use. Therefore, integrating CLO2 generation into the normal process of treating flowback water can result in significant efficiency and cost improvements. By using EWS, operators can produce CLO2 to process water for re-use with the added benefit of no additional CLO2 generator infrastructure requirement. Additional benefits of CLO2 production within the EWS process flow are expected to not only help remove bacteria, but help save on capital costs of replacing pipe and other infrastructure, as CLO2 is known to oxidize and destroy friction generating chemicals." "OriginOil disclosed the proprietary capability of EWS to generate chlorine dioxide in a patent application filed on July 15th, 2013, titled "Removing Ammonia from Water". This patent describes how EWS acts and induces reactions on chlorine-based elements."

There is significant evidence that, in living systems, free radicals and other reactive oxygen and nitrogen species play a double role, because they can cause oxidative damage and tissue dysfunction and serve as molecular signals activating stress responses that are beneficial to the organism. Mitochondria have been thought to both play a major role in tissue oxidative damage and dysfunction and provide protection against excessive tissue dysfunction through several mechanisms, including stimulation of opening of permeability transition pores. Until recently, the functional significance of ROS sources different from mitochondria has received lesser attention. However, the most recent data, besides confirming the mitochondrial role in tissue oxidative stress and protection, show interplay between mitochondria and other ROS cellular sources, so that activation of one can lead to activation of other sources. Thus, it is currently accepted that in various conditions all cellular sources of ROS provide significant contribution to processes that oxidatively damage tissues and assure their survival, through mechanisms such as autophagy and apoptosis.

Biofilm is a complex structure of microbiome having different bacterial colonies or single type of cells in a group; adhere to the surface. These cells are embedded in extracellular polymeric substances, a matrix which is generally composed of eDNA, proteins and polysaccharides, showed high resistance to antibiotics. It is one of the major causes of infection persistence especially in nosocomial settings through indwelling devices. Quorum sensing plays an important role in regulating the biofilm formation. There are many approaches being used to control infections by suppressing its formation but CRISPR-CAS (gene editing technique) and photo dynamic therapy (PDT) are proposed to be used as therapeutic approaches to subside bacterial biofim infections, especially caused by deadly drug resistant bad bugs.

Decontamination of Bacillus spores adhered to common drinking water infrastructure surfaces was evaluated using a variety of disinfectants. Corroded iron and cement-mortar lined iron represented the infrastructure surfaces, and were conditioned in a 23 ...

*****!!!!**** {This article only mentions chlorine dioxide effectiveness against SARS-CoV-1, not SARS-CoV-2, against which it has greater effectiveness} "The exposure of SARS-CoV-2 (7.8 of log10 (TCID50/ml) to 1:49 (~150 ppm) and 1:99 (~75 ppm) *household bleach* resulted in the virus titer being reduced below levels of detection after 5 min" "The aim of this review is to provide information, primarily to the food industry, regarding a range of biocides effective in eliminating or reducing the presence of coronaviruses from fomites, skin, oral/nasal mucosa, air, and food contact surfaces. As several EPA approved sanitizers against SARS-CoV-2 are commonly used by food processors, these compounds are primarily discussed as much of the industry already has them on site and is familiar with their application and use. Specifically, we focused on the effects of alcohols, povidone iodine, quaternary ammonium compounds, hydrogen peroxide, sodium hypochlorite (NaOCl), peroxyacetic acid (PAA), chlorine dioxide, ozone, ultraviolet light, metals, and plant-based antimicrobials. This review highlights the differences in the resistance or susceptibility of different strains of coronaviruses, or similar viruses, to these antimicrobial agents."

{Water carbonate hardness (from calcium & magnesium ions) doesn't affect CD activity.} Chlorine dioxide is oxidized by Fe2+ and Mn2+ ions to precipitate ferric hydroxide and manganese oxide, respectively (7). Chlorine dioxide does not react with ammonia, bromides, nitrate, hard water, and zinc. Mn was determined to be highly influential on the biocidal activity of ClO2, Fe to have a small but negligible effect, and Cu and Zn to have no effect on ClO2 activity.
