“…To overcome this limitation, the use of yeast in bioreactors could be a way forward. Some yeasts able to reduce COD and phenolic content of OMWs include Geotrichum candidum (Assas et al 2000;Giannoutsou et al 2004), Candida tropicalis (Fadil et al 2003), Candida boidinii and Saccharomyces sp.

Olive-mill wastes are produced by the industry of olive oil production, which is a very important economic activity, particularly for Spain, Italy and Greece, leading to a large environmental problem of current concern in the Mediterranean basin. There is as yet no accepted treatment method for all the wastes generated during olive oil production, mainly due to technical and economical limitations but also the scattered nature of olive mills across the Mediterranean basin. The production of virgin olive oil is expanding worldwide, which will lead to even larger amounts of olive-mill waste, unless new treatment and valorisation technologies are devised. These are encouraged by the trend of current environmental policies, which favour protocols that include valorisation of the waste. This makes biological treatments of particular interest. Thus, research into different biodegradation options for olive-mill wastes and the development of new bioremediation technologies and/or strategies, as well as the valorisation of microbial biotechnology, are all currently needed. This review, whilst presenting a general overview, focusses critically on the most significant recent advances in the various types of biological treatments, the bioremediation technology most commonly applied and the valorisation options, which together will form the pillar for future developments within this field.

“…The resulting solid waste is about 800 kg per ton of processed olives. This ''alpeorujo'' still contains 2.5-3.5% residual oil and about 60% water in the two-phase decanter system (Giannoutsou et al 2004 The average amount of OMWs produced during the milling process is approximately 1000 kg per ton of olives (Azbar et al 2004). 19.3 million tons of olive are produced annually worldwide, 15% of them used to produce olive oil (FAOSTAT 2009).…”

“…Moreover, olive oil production is no longer restricted to the Mediterranean basin, and new producers such as Australia, USA and South America will also have to face the environmental problems posed by OMWs. The management of wastes from olive oil extraction is an industrial activity submitted to three main problems: the generation of waste is seasonal, the amount of waste is enormous and there are various types of olive oil waste (Giannoutsou et al 2004). …”

“…In fact, several studies have reported phytotoxic and antimicrobial effects of this residue due to the phenol (Aranda et al, 2007;Sampedro et al, 2007a). Efforts to decrease the environmental impact of olive-mill wastes include biological fermentation with saprophytic fungi (Linares et al, 2003;Giannoutsou et al, 2004;Sampedro et al, 2007b). It has been shown that phytotoxicity of DOR can be reduced by incubating it with some inmobilized saprophytic fungi for 4 weeks .…”

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...
