ISOLATION OF MICROORGANISMS WITH CAPABILITY TO DEGRADE POLYCYCLIC AROMATIC HYDROCARBONS (PAH'S)
This paper summarizes a work conducted on the isolation of microorganisms from PAH's contaminated sediments. The methodology involved two selection systems called fast route and slow route in which exposure periods and contaminant concentrations are the key determinants. The microorganisms isol...

description | This paper summarizes a work conducted on the isolation of microorganisms from PAH's contaminated sediments. The methodology involved two selection systems called fast route and slow route in which exposure periods and contaminant concentrations are the key determinants. The microorganisms isolated through the slow route system are more likely to be successful in degrading high molecular weight PAH's. The six strains obtained through the fast route system were able to grow on low molecular weight PAH's showing preference towards the first four EPA (Environmental Protection Agency) priority PAH's.<br>Este estudio presenta el aislamiento microbiológico en muestras de sedimento contaminado con un alto porcentaje de hidrocarburos aromáticos polinucleares (Polynuclear Aromatic Hydorcarbons, PAHs). La metodología utilizada comprende dos sistemas de selección denominados vía rápida y vía lenta. Estas vías tienen como condiciones determinantes el tiempo de exposición y la concentración del contaminante de interés. Los microorganismos aislados mediante la vía lenta garantizan mayor probabilidad de éxito en el proceso de biodegradación de PAHs con compuestos de alto peso molecular. Seis cepas con capacidad de crecer en PAHs de bajo peso molecular obtenidos por la vía rápida, mostraron preferencia por los primeros cuatro compuestos, de los dieciséis exigidos por la EPA (Environmental Protection Agency). |
