Biorremediación y fitorremediación de un suelo impactado por aceite residual automotriz con Helianthus annuus y Burkholderia vietnamiensis

Abstract

Soil contaminated by of waste motor oil (WMO) a mix of aliphatic, aromatic hydrocarbon’s caused living soil inhibition and to reduce agriculture production. Nom-138 Semarnat/ISS-2003 indicated that maximum concentration at soil accepted is 4400 ppm. To solve this problem chemical methods are apply however they spencil and caused collateral environmental damage. An ecological alternative is Bioremediation (BR) by Biostimulation (BS) or/and Phytoremediation (PR) which to explode it´s potencial to mineralize hydrocarbons. The aim of this research was BR) of soil polluted by 20000, 30000 and 45000 ppm of WMO by biostimulation (BS) adding mineral solution and Vicia sativa as green manure, then phytoremediation (PR) by Helianthus annus potencied with Burkholderia vietnamiensis to reduce WMO at values below to accept by the Nom -138 Semarnat/ISS-2003. These results to support that BS by sequential, accumulative or integral by enrichment of inorganic and organic nutrients due to mineral solution and incorporation and degradation of V. sativa reduced WMO at then PR using H. annus and B. vietnamiensis was an efficient way to eliminate WMO.
