“…We assume that the presence of phenolic compounds on olive oMW suppresses pathogen mycelium and possibly it could offer a protection on fruits from post-harvest diseases such as Botrytis fruit rot (gray mold). Similar results have been reported (3,12) for olive mill residues to affect saprophytic growth and disease incidence of foliar, soilborne and post harvest plant pathogens same as B. cineria that was presented in this study.…”

“…One alternative and economical solution is the use of olive mill wastewater (OMW), to reduce soil-borne plant pathogens in many crops and postharvest rot diseases of flower bulbs (Smid et al, 1995;Kotsou et al, 2004). In addition, aerobic biological of OMW and their use in agriculture to protect plant material from storage fungi (Bonanomi et al, 2006) will contribute to the reduction of the environmental pollution, since OMW constitutes a major environmental problem due to its high content in phenolic compounds as tannins and flavonoids (Hamdi, 1992;Gonzales et al, 1999).…”

The effect of olive mill wastewater (OMW) on growth of tulip plants infected by common diseases as well as on their new bulbs production is analyzed in this work. Filtered and sterilized OMW was tested as growth inhibitor of Botrytis tulipae, Fusarium oxysporum, Aspergillus niger and Penicillium spp. mycelium. The effect of filtered OMW on uninfected tulip bulbs was also tested as well as on the growth of bulbs infected with the fungus B. tulipae and A. niger in vivo. The mycelium length, severity of scab-like lesions, plant height (PH), fresh mass (FM) and dry mass (DM) of plants and production of new bulbs were recorded. Only the filtered OMW inhibited the in vitro mycelium growth of all tested fungi. However filtered OMW caused infections when it sprayed on uninfected bulbs, malformations on 30% of the plants grown from these bulbs and decrease PH, FM and DM as well as new bulbs production at 75%, 72.4%, 79.1% and 50% respectively. The treatment of B. tulipae infected bulbs with filtered OMW reduced further the PH, FM, DM and the production of new bulbs in 92.1%, 81.4%, 78.7% and 97% respectively. In contrast the treatment of infected bulbs by B. tulipae + A. niger with filtered OMW did not affect PH, FM and the number of new bulbs produced and significantly improved plants DM and the mass of new bulbs.

“…AM fungi may facilitate the action or transfer of toxic substances to the plants, increasing the sensitivity of plant to the toxicity of DOR and this sensitivity seems to be dependent on AM fungal species (Martin et al, 2002;Bonanomi et al, 2006). In fact, the sensitivity of tomato plant to the toxicity of DOR was different when they were colonized with G. deserticola or with the indigenous AM fungi .…”

We studied the influence of indigenous arbuscular mycorrhizal (AM) and saprobe fungi on the phytotoxicity of the physical fractions of dry olive mill residue (DOR). The physical extractions of DOR gave an aqueous (ADOR) and an exhausted (SDOR) fraction with less phytotoxicity for tomato than the original samples. The indigenous AM were able to decrease the phytotoxicity of SDOR inoculated with Trametes versicolor and Pycnoporus cinnabarinus on tomato. However, incubation of ADOR with both saprophytic fungi did not decrease its phytotoxicity in presence of the indigenous AM fungi. The percentage of root length colonized by indigenous AM strongly decreased in presence of DOR, around 80% of decrease at dose of 25 g kg -1 of DOR, but the level of mycorrhization was higher in presence of ADOR or SDOR (38% and 44% of decrease respectively at the same dose). There were no relationships between the effects of the physical fractions of DOR incubated with the saprobe fungi on AM colonization and on plant dry weight of tomato. Our results suggest that the phytotoxicity of the olive residues can be eliminated by the combination of physical extraction and by saprobe fungal inoculation and the use of this agrowaste as organic amendment in agricultural soil may be possible.Additional key words: biofertilizer, bioremediation, olive waste, phytotoxicity, saprobe fungi, Solanum lycopersicum L. ResumenMateria seca y colonización de raíces de plantas por hongos micorrícico arbusculares autóctonos en presencia de fracciones físicas de alpeorujo seco y extractado inoculado con hongos saprobios En este trabajo se ha estudiado la influencia de los hongos micorrízicos arbusculares autóctonos y hongos saprobios en la fitotoxicidad de las fracciones físicas del alpeorujo. La extracción física del alpeorujo con agua produjo un extracto acuoso (ADOR) y un sólido extractado (SDOR) con menor fitotoxicidad para las plantas de tomate que los controles con alpeorujo. Los hongos arbusculares autóctonos son capaces de disminuir la fitotoxicidad de SDOR inoculado con Trametes versicolor y Pycnoporus cinnabarinus en plantas de tomate. Sin embargo, la incubación del ADOR con dichos hongos no modificó la fitotoxicidad del residuo en plantas de tomate cultivadas en suelo no estéril. El porcentaje de longitud de raíz colonizada por los endófitos arbusculares autóctonos disminuyó drásticamente en presencia de alpeorujo (alrededor de un 80% de disminución a la dosis de 25 g kg -1 de DOR) aunque el nivel de micorrización fue superior en presencia de ADOR o SDOR (38 y 44% de disminución a la misma dosis). No se ha encontrado relación entre los efectos de las fracciones físicas del alpeorujo incubado con hongos saprobios en la colonización arbuscular y el peso seco de las plantas de tomate. Nuestros resultados indican que la fitotoxicidad de los residuos del olivar puede ser eliminada por el uso combinado de una extracción física y una incubación biológica con hongos saprobios; por tanto podemos considerar el uso de estos residuos como enmendantes or...
