          Resumen En México un suelo impactado por 90000 ppm de aceite residual automotriz (ARA), excede la máxima concentración permitida de 4400 ppm según la NOM-138-SEMARNAT/SSA1-2003 (NOM-138) y que le causa infertilidad. Una alternativa solución es la por bioestimulación (BIS) integral con un detergente, una solución mineral, con H2O2 fuente O2, un extracto fúngico crudo con una lacasa que hidroliza aromáticos del ARA, luego con Phaseolus vulgarís o abono verde. Estas acciones se concluyen por fitorremediación (FITO) mediante Cicer aretinum. Los objetivos de esta investigación fueron: i) BIS de un suelo impactado por 90000 ppm de ARA, ii) FITO mediante C. aretinum con Micromonospora echinospora y Penicillium chrysogenum para decrecer el ARA a valor inferior al máximo aceptado de la NOM-138. En suelo la variable-respuesta de la BIS fue la concentración inicial y final de ARA por Soxhlet, en la FITO se registró la fenología y biomasa de C. aretinum a plántula. Los datos experimentales se analizaron por ANOVA/Tukey HSD P<0.05%. Los resultados muestran que la BIS y FITO en suelo impactado por 90000 ppm de ARA, lo decrecieron hasta 1200 ppm, valor numérico estadísticamente distinto comparado con suelo con 79000 ppm de ARA sin BIS ni FITO o control negativo. Se concluye que en suelo impactado por una relativa alta concentración de ARA la BIS y FITO fue estrategia integral suficiente para recupera acorde con la NOM-138.

          Abstract In México any soil polluted by 90000 ppm waste motor oil (WMO), this concentration is over the maximun acepted of 4400 ppm by regulation law called as a NOM-138-SEMARNAT / SSA1-2003 (NOM-138), 9000 ppm of WMO is causing soils fertility decreasing. An alternative solution is biostimulation (BIS) by detergent following by mineral solution then. Subsequently the BIS by H2O2 as a supplier of O2 and a crude fungi extract containing lacease able to hydrolyze aromatic of WMO, then by Phaseolus vulgarís as a green manure to reduce WMO; concluding by phytoremediation (PHYTO) with Cicer aretinum The objectives of this research were: i) BIS of soil contaminated by 90000 ppm of WMO ii) PHYTO by C. aretinum with Micromonospora echinospora and Penicillium chrysogenumlo decrease WMO at lower concentration valué than the máximum accepted by NOM-138. In sense at soil's, variable-response of BIS was initial and final concentration of WMO by Soxhlet, at the PHYTO, phenology and biomass of C. aretinum were taken at seedling. The experimental data were analyzed by ANOVA/Tukey HSD P <0.05%. Results showed that BIS and PHYTO of soil impacted by 90000 ppm of WMO decreased until 1200 ppm numerical valué statistically different compared to 79000 ppm of soil polluted by WMO, without BIS and either PHYTO or negative control. Those results showed that BIS and PHYTO are an effective technique for recovering soil polluting by relative high level of WMO according to NOM-138.

            Potential of Penicillium Species in the Bioremediation Field

            The effects on the environment of pollution, particularly that caused by various industrial activities, have been responsible for the accelerated fluxes of organic and inorganic matter in the ecosphere. Xenobiotics such as phenol, phenolic compounds, polycyclic aromatic hydrocarbons (PAHs), and heavy metals, even at low concentrations, can be toxic to humans and other forms of life. Many of the remediation technologies currently being used for contaminated soil and water involve not only physical and chemical treatment, but also biological processes, where microbial activity is the responsible for pollutant removal and/or recovery. Fungi are present in aquatic sediments, terrestrial habitats and water surfaces and play a significant part in natural remediation of metal and aromatic compounds. Fungi also have advantages over bacteria since fungal hyphae can penetrate contaminated soil, reaching not only heavy metals but also xenobiotic compounds. Despite of the abundance of such fungi in wastes, penicillia in particular have received little attention in bioremediation and biodegradation studies. Additionally, several studies conducted with different strains of imperfecti fungi, Penicillium spp. have demonstrated their ability to degrade different xenobiotic compounds with low co-substrate requirements, and could be potentially interesting for the development of economically feasible processes for pollutant transformation.

              Gibberellins in Penicillium strains: Challenges for endophyte-plant host interactions under salinity stress.

              The genus Penicillium is one of the most versatile "mycofactories", comprising some species able to produce gibberellins, bioactive compounds that can modulate plant growth and development. Although plants have the ability to synthesize gibberellins, their levels are lower when plants are under salinity stress. It has been recognized that detrimental abiotic conditions, such as saline stress, have negative effects on plants, being the availability of bioactive gibberellins a critical factor for their growth under this conditions. This review summarizes the interplay existing between endophytic Penicillium strains and plant host interactions, with focus on bioactive gibberellins production as a fungal response that allows plants to overcome salinity stress.
