Resumen

Los hidrocarburos aromáticos policíclicos (HAP) son compuestos tóxicos para los seres humanos que se pueden acumular en el medio ambiente. Pseudomonas es un género que comprende bacterias que preferiblemente utilizan HPA como fuente de carbono. En este trabajo, la expresión de enzimas de la vía de degradación del naftaleno fue inducida en P. aeruginosa, que se encuentra comúnmente en suelos brasileños, y cuyo potencial biorremediador aún no ha sido explorado. Las fracciones cromatográficas obtenidas se analizaron para determinar la degradación del naftalina DE HAP, in vitro. Algunas de las fracciones fueron capaces de realizar la catálisis, indicando la presencia de las enzimas responsables del proceso y señalando un uso potencial de ellas fuera del microambiente bacteriano.
