p-Anisaldehyde exerts its antifungal activity against Penicillium digitatum and Penicillium italicum by disrupting the cell wall integrity and membrane permeability. J Microbiol Biotechnol. 2020 Mar 09;: Authors: Che J, Chen X, Ouyang Q, Tao N Abstract Penicillium digitatum and Penicillium italicum are the two important postharvest pathogens in citrus, which cause about 90% of the total loss of citrus fruit during the storage and transportation. The natural fungicides such as essential oils were widely used for preventing and controlling the postharvest diseases instead of chemical fungicides. In this research, p-anisaldehyde exhibited a strong inhibitory effect on P. digitatum and P. italicum, with the MIC and MFC values of both being 2.00 µL/mL. Additionally, p-anisaldehyde visibly inhibited both the green mold and blue mold development of citrus fruits inoculated with P. digitatum and P. italicum. The mycelia morphologies of these pathogens were greatly altered, and the membrane permeability and cell wall integrity of mycelia were severely disrupted under p-anisaldehyde treatment. Results suggest that the antifungal activity of p-anisaldehyde against P. digitatum and P. italicum can be attributed to the disruption of the cell wall integrity.
