Resumen

Se preparó un nanocompuesto a base de bentonita organófila (BO) y acetato de geranilo (AG) en agitador durante 1 hora, 180 rpm y temperatura ambiente, siendo posteriormente secado en estufa a 90 ºC±2 ºC durante 48 horas. Luego, este material se caracterizó por su actividad antibacteriana contra Staphylococcus aureus y Escherichia coli y antifúngica contra Aspergillus flavus y Aspergillus niger, respectivamente. Además, se evaluó la capacidad de adsorción de BO y BO/AG utilizando Aflatoxina B1 en la concentración de 107 µg∙L-1. Después de 17 h, el compuesto eliminó una cantidad significativa de micotoxinas, estando por debajo de 20 µg∙L-1. Los resultados mostraron que este compuesto tiene una buena capacidad de adsorción, puede ser eficaz en la eliminación de micotoxinas en medios acuosos y una excelente actividad antibacteriana y antifúngica.
