RESUMEN: Se evaluó la degradación del insecticida clorpirifos en muestras de suelo durante 21 días, utilizando el hongo Phanerochaete chrysosporium. En los ensayos se obtuvieron porcentajes de degradación, en promedio, para las muestras con hongo, de 96,3, 82,4 y 62,2% cuando se trabajaron, respectivamente, con concentraciones iniciales de clorpirifos de 0,95, 5,3 y 9,4 µg/g. Igualmente, los porcentajes de degradación estuvieron acompañados del aumento en la velocidad de degradación, cuando se partió de la concentración inicial de 0,95 µg/g.
ABSTRACT: Degradation of the insecticide chlorpyrifos was investigated in sterilized soil samples supplemented by the white rot basidiomycete Phanerochaete chrysosporium. Degradation rates were measured during 21-day incubation at pesticide concentrations of 0,95, 5,3, and 9,4 µg/g. Phanerochaete chrysosporium showed ability to biodegrade the insecticide in values of 96,3%, 82,4% and 62,2%, respectively, followed by rapid degradation at low initial concentration of chlorpyrifos.
