I'm trying to use sodium thiosulfate to arrest the reaction of sanitizers on my fungal spores after the holding period is over. As sodium thiosulfate is the best to take away the chemical, especially the peracetic acid but I found this could be antifungal too. Any suggestions? Does anyone know the concentration of sodium thiosulfate that could be safe while working with Mucor and Botrytis spores? Thank you.
