| 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 chrysogenum 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 bioremediation 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 |
