“…The k values were 0.038 and 0.033 L mg −1 min −1 for A. niger and A. flavus with 10.0 mg L −1 PAA in 45 min, respectively. It can be mentioned that the inactivation of the target fungi was attributed to oxidizing action after cell membrane penetration by PAA rather than cell membrane damage [135].…”

The introduction of the first list of priority pathogenic fungi by the World Health Organization stresses the need to research and develop public health actions to mitigate infections caused by fungi. One of those actions involves the water disinfection systems, which comprise classical and alternative methods that have been developed in the last decades. Thereby, this work reviews the disinfection of fungi by classical methods such as chlorination, ozonation, and ultraviolet (UV) treatments and alternative advanced oxidation processes (AOPs) such as photo-Fenton, photocatalysis, or couplings of UV with peroxides. The matrices of aquatic systems (sewage, groundwater, drinking water, among others) were considered. A bibliometric analysis is performed initially, and then some aspects of the resistance to antifungals are presented, and the efficiency of the diverse processes in the reduction in fungal loading is also revised. Herein, it is shown the role of the disinfecting agents (e.g., chlorine, hydroxyl radical, or light) and their effects on fungi structures (e.g., direct DNA damage, or indirect damage due to the action of radicals). Moreover, gaps, such as the treatment of antifungal-resistant fungi and limited information about combinations among AOPs, related to the disinfection of water polluted by fungi, were identified.

“…Controlling fungus contamination in water and creating more potent disinfection techniques to destroy fungi are crucial. 23 Various ongoing research efforts focus on finding the safe and effective methods for fungal eradication. PAA, which is paracetic acid, can inactivate the fungal spores by penetrate into their membrane.…”

Bioaerosol containing fungal spores became public health hazards. The aerosols contain the fungal spores of different species of Aspergillus, Cladosporium, Chaetomium, Penicillium, Wallemia, Stachybotrys etc. and caused various life-threatening respiratory diseases such as hypersensitivity, pneumonia, Aspergillosis, Candidiasis, Mucormycosis, Cancer, etc. They are easily transmitted from one individual to another. They also cause extreme damage to crops and create problems in food security by producing mycotoxins. The transmissions of fungal spores depend upon the environmental factor, seasonal variation, growth surface, type of fungal spore, etc. There are various biophysical, biochemical and molecular techniques that are present to detect fungal spores in aerosol. There are numerous physical and chemical agents that can kill fungi. Good public health and food security can be achieved through the detection and management of fungal spores in aerosols.

“…Sample preparation was based on previous studies [47,48] with some modifications. To detect changes in spore morphology, fungal spore suspensions from the experimental and control groups were first centrifuged at 10,000 rpm for 15 min, the supernatant was discarded, and then, 3% glutaraldehyde was added and stored in a refrigerator at 4 • C overnight.…”

Ginger soft rot is a serious soil-borne disease caused by Fusarium solani and Fusarium oxysporum, resulting in reduced crop yields. The application of common chemical fungicides is considered to be an effective method of sterilization, and therefore, they pose a serious threat to the environment and human health due to their high toxicity. Benzalkonium chloride (BAC) and benzethonium chloride (BEC) are two popular quaternary ammonium salts with a wide range of fungicidal effects. In this study, we investigated the fungicidal effects of BAC and BEC on soft rot disease of ginger as alternatives to common chemical fungicides. Two soft rot pathogens of ginger were successfully isolated from diseased ginger by using the spread plate method and sequenced as F. solani and F. oxysporum using the high-throughput fungal sequencing method. We investigated the fungicidal effects of BAC and BEC on F. solani and F. oxysporum, and we explored the antifungal mechanisms. Almost complete inactivation of spores of F. solani and F. oxysporum was observed at 100 mg/L fungicide concentration. Only a small amount of spore regrowth was observed after the inactivation treatment of spores of F. solani and F. oxysporum in soil, which proved that BAC and BEC have the potential to be used as an alternative to common chemical fungicides for soil disinfection of diseased ginger.
