El objetivo de este estudio fue investigar la actividad antifúngica del citral contra Cladosporium sphaerospermum, mediante la determinación de la concentración mínima inhibitoria (CMI) y la concentración mínima de fungicida (CMF), los efectos sobre el crecimiento micelial y la germinación de conidios, y también investigar la posible acción de citral en paredes celulares y membranas celulares. La CMI del citral varió de 128 a 256 µg/mL y la CMF varió de 256 a 1024 µg/mL. La CMI50 y CMF50 fueron, respectivamente, 128 µg/mL y 256 µg/mL. El citral inhibió el desarrollo micelial y la germinación de conidios y mostró interacción con ergosterol. Estos datos indican que el citral tiene una fuerte actividad antifúngica, que puede estar relacionada con su interacción con el ergosterol.
The aim of this study was to investigate the antifungal activity of citral against Cladosporium sphaerospermum, by determining the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC), effects on mycelial growth and conidia germination, and also investigated the possible action of citral in cell walls and cell membranes. The MIC of citral ranged from 128 to 256 µg / ml and the MFC ranged from 256 to 1024 µg/mL. The MIC50 and MFC50 were, respectively, 128 µg/mL and 256 µg/mL. Citral inhibited mycelial development and conidia germination and showed interaction with ergosterol. These data indicate that citral has strong antifungal activity, which may be related to its interaction with ergosterol.
