pH-dependent virucidal effects of acetate, oxalate, and citrate against FulV, SARS-CoV-2, and FCV. Acetate, oxalate, and citrate adjusted at pH 2, 4, and 6 were mixed with each virus for 1, 10 and 30 min. Negative control (NC) was incubated with distilled water instead of weak acids. Infectious viral titers (pfu/ml) of FulV (A), SARS-CoV-2 (B), and FCV (C) were determined. Error bars indicate the standard error. Detection limit was set to 103 pfu/ml. Each viral inactivation was accessed in triplicate
