    In soil spill a high concentration of waste motor oil (WMO) it麓s causing lost soil fertility, which is solved by remediation, but is expensive and polluting, an ecological alternative is bioremediation (BR) by biostimulation follow by phytoremediation (PY) with Sorghum bicolor using Burkholderia cepacia and Penicillium chrysogenum, promoting growthplant microorganisms (PGPM) at concentration value below to the maximum according to NOM-138 SEMARNAT/SS- 2003 de 4400 ppm/Kg soil. The objectives of this research were a) bioremediation of soil contaminated by high WMOconcentrations by biostimulation with mineral solution and Vicia sativa as green manure (GM), and subsequent b)phytoremediation by S. bicolor with B. cepacia and P. chrysogenum to reduce remaining WMO at concentration belowto maximum according to NOM-138 SEMARNAT/SS-2003. The results showed that biostimulation with mineralsolution and V. sativa reduced WMO from 55000 to 33400 ppm, and from 65000 to 24300 ppm. Follow by PY by S.bicolor with B. cepacia and P. chrysogenum decreased WMO from 33400 ppm to 210 ppm, and from 24300 ppm to 360ppm, compared to soil as negative control in which WMO did not change by natural attenuation. This suggests that tointegrate BR and PY is an ecological option instead to apply chemical technique expensive and causing environmentalpollution.En suelo una elevada concentraci贸n de aceite residual automotriz (ARA) una mezcla de hidrocarburos alif谩ticos yarom谩ticos, provoca p茅rdida de su fertilidad. Una soluci贸n es aplicar la remediaci贸n qu铆mica que es costosa y causacontaminaci贸n colateral. En contraste una alternativa ecol贸gica es la biorremediaci贸n (BR) por bioestimulaci贸n (BS),seguida de fitorremediaci贸n (FR) con Sorghum bicolor y microorganismos promotores del crecimiento vegetal (MPCV)para reducir el ARA a un valor inferior al m谩ximo permisible por la NOM-138 SEMARNAT/SS-2003 de 4400 ppm/Kgde suelo. Los objetivos de esta investigaci贸n fueron: i) BR de suelo contaminado con 55000 y 65000 ppm de ARA porbioestimulaci贸n; y ii) FR con Sorghum bicolor inoculado con Burkholderia cepacia y Penicillium chrysogenum NOM- 138 SEMARNAT/SS-2003. As铆 en ese suelo la BS con una soluci贸n mineral (SM) y Vicia sativa como abono verde(AV) redujeron el ARA de 55000 a 33400 ppm y de 65000 a 24300 ppm. Posteriormente la FR con S. bicolor con B.cepacia y P. chrysogenum (MPCV), el ARA decreci贸 de 33400 ppm a 210 ppm, y de 24300 a 360 ppm, ambos valoresinferiores al m谩ximo permisible por NOM-138 SEMARNAT/SS-2003. Comparado con el mismo suelo control negativocon ARA, sin BR y FR, ah铆 la atenuaci贸n natural no cambio la cantidad de ARA. Lo anterior apoya la integraci贸n de laBR/FR en suelo impactado con elevadas concentraciones de ARA, como una opci贸n ecol贸gica en sustituci贸n de remediaci贸n qu铆mica costosa y contaminante

    Bean is a legume its production requires nitrogen (N) combined as ammonium (NH4) or nitrate (NO3) and phosphates (NPF), its indiscriminate application causes soil lost productivity. An alternative solution for reducing and optimizing NPF is applying mixed inoculant which could be improved by plant growth promoting bacteria (PGPB) and mycohrrizae. The objective of this research was to analyze the response of beans to mixed inoculant Endospor 33庐 at 50% reduced dose of NPF. In that sense a red ferralitic soil poor in N and organic matter was used. By experimental design: 5 treatments and 6 replications. Results showed a positive bean responds achieving 100% germination at 20mg/seed with Endospor 33庐 at 50% NPF dose. At seedling level bean was 6.63g of total fresh weight (TFW) and 0.66g total dry weight (TDW) with the same Endospor 33庐 dose compared to 0.28g of TDW of bean used as relative control (RC) at 100% NPF dose. At flowering with 30 mg/plant got 1.5 g of TDW compared to 1.0g TDW of bean as CR. At physiological maturity bean with 30mg/plant had 34.83g/100 grains compared to 20.39g/grains of bean as CR. Those data supporting that Endopre 33庐 is an excellent choice in beans production at NPF 50% dose but not adverse effect on bean growth and yield in protected agriculture.El frijol requiere fertilizaci贸n nitrogenada y fosfatada (FNP), cuya indiscriminada aplicaci贸n causa p茅rdida de productividad del suelo, una alternativa de soluci贸n para este problema es reducir y optimizar la dosis de FNP con un inoculante mixto con bacterias promotoras de crecimiento vegetal (BPCV) y hongos micorricicos ves铆culo arbusculares (HMA). El objetivo de esta investigaci贸n fue analizar la respuesta del frijol al inoculante mixto Endospor 33庐 a dosis reducida al 50% del FNP. En un suelo ferral铆tico rojo pobre de Nitr贸geno (N) y materia org谩nica. Con un dise帽o experimental de bloques al azar con 5 tratamientos y 6 repeticiones. Los resultados indican que el porcentaje de germinaci贸n del frijol con Endospor 33庐 a la dosis 20 mg/semilla fue de 100%. A pl谩ntula con 10 mg/planta, tuvo 6,13g de peso fresco total (PFT) y de 0,66g de peso seco total (PST) comparado con el frijol control relativo (CR) con 0,28g de PST con el 100% del FNP. A floraci贸n con 30 mg/planta Endospore 33庐 tuvo 1,5g de PST comparado con 1,07g de PST del frijol CR. A madurez fisiol贸gica con 30mg/planta registro 34,83g/100 semillas, en contraste a su homologo CR con 20,39g/100 semillas. Lo anterior indica que este inoculante mixto es una opci贸n en la producci贸n del frijol a dosis reducida del FNP, sin afectar negativamente su crecimiento y/o rendimiento
