“…The understanding of the mechanisms of weak acid stress resistance is also crucial to guide their use as therapeutics (e.g. the analgesic acetylsalicylic acid, the immunosuppressor mycophenolic acid and the antimalarial drugs artesunic and artemisinic acids), as herbicides (e.g. 2,4-dichlorophenoxyacetic (2,4-D) or as food-preservatives (e.g. acetic, propionic and sorbic acids). …”
