| Popis: | In Mexico, a soil poor in nitrogen (N) polluted by 100000 ppm of waste motor oil (WMO) is an environmental problem also because is drastically affecting soil´s proprieties related with mineralization of organic matter and lost its fertility since exceeding the maximum accepted limit of 4400 ppm of the Mexican environmental rule called NOM-138-SEMARNAT-2012 (NOM-138). An ecological alternative to solve it is to treat for eliminating WMO and to recover its fertility. Therefore, the aims of this research were: a) bioremediation of soil polluted by 100000 ppm of WMO b) phytoremediation by Sorghum vulgare with Aspergillus niger and Penicillium chryso-genum to decrease WMO´s concentration at lower value of 4400 ppm accepted by the NOM-138. In that sense the variable response to measure soil´s recovering was: a) WMO´s concentration with Soxhlet, after bioremedia-tion and phytoremediation b) while at phytoremediation the phenology and biomass at seedling stage of S. vulgare with A. niger and P. chrysogenum. All experimental data were validated by ANOVA/Tukey HSD P |
