In Mexico and in the world, a problem of contamination in domestic water is due to petroleum derivatives such as waste motor oil (WMO), whose chemical composition is aliphatic and aromatic hydrocarbons. An ecological solution is to biostimulation with extracellular enzimes of Pleurotus florida and mineral solution to eliminate both by the aerobic native heterotrophic microbiota. The objective of this research was to analyze the bioremediation of domestic water polluted by benzene of WMO with an extract of P. florida and mineral solution. In that sense, P. florida was grown in straw with lignin content, that induces enzymes to hydrolyze benzene for 5 days, for obtaining crude extract of P. florida (ePf). This ePf used for the biostimulation of domestic water polluted by benzene from WMO and a mineral solution: to oxidate the benzene that was measured by CO2 generated from its mineralization and mass-coupled gas chromatography to demonstrate its elimination. The results indicate that in biostimulation of domestic water polluted by benzene from WMO with ePf, caused its hydrolysis followed by the mineral solution that eliminated it. Compared to domestic water polluted by benzene from WMO non biostimulated by ePf neither mineral solution where benzene did not disappear. This data supports biostimulation domestic water polluted by benzene from WMO with ePf and mineral solution for its rapid reutilization.
