“…In fact untreated OMWW are able to change the microbial composition of the soil through their antibacterial activity (Borya et al 1995;Tardioli et al 1997) and to produce phytopathogenic effects due to their high toxicity (Bressan et al 2004). In recent years, some methods have been proposed for OMWW bioremediation, such as chemical or microbiological treatment (Fountoulakis et al 2002;Isadori et al 2004;Kissi et al 2001;Maullu et al 1999;RigoniStern et al 1988;Sayady and Ellouz 1993). Some systems were also patented (Brueggemann and Huebner 2002;Catalano and De Nobili 2002;Reverso 1999).…”

Olive oil mill wastewater (OMWW) was used as a substrate for the culture of a mixture of edible fungi in order to obtain a potentially useful microbial biomass and to induce a partial bioremediation of this fastidious waste. Before fermentation, the OMWW underwent an alkaline-oxidative treatment with the aim of decreasing the polyphenolic content which is the main cause of its toxicity. The fungal mixture grew fairly well in the treated OMWW and reached a maximum of biomass production within about 14 days of fermentation at room temperature. Up to 150-160 g of wet biomass was obtained per liter of OMWW. Analysis of the partially dehydrated biomass revealed a protein content of about 13 g% and 6 g% of row fiber. A relevant presence of unsaturated fatty acids was found, as well as the presence of significant amounts of vitamins A and E, nicotinic acid, calcium, potassium and iron. The possibility of using the microbial biomass produced from OMWW as an additive to animal feed is discussed.

Jordan watersheds heavily suffer from the seasonal discharge of highly concentrated olive mill wastewater (OMW). Environmental concern and protection of the scarcely available water resources calls for adequate treatment of OMW prior to discharge. This paper describes an inventory that was made with the aim of developing pollution prevention strategies for the olive mill sector of the Jerash Governorate in Jordan. Emphasis was given to compiling regional research which shows that modern anaerobic technology may play an important role in treating the highly concentrated OMW. The paper also presents pre and post treatment options for achieving local discharge criteria. Based on literature review and current insights three innovative treatment strategies are presented for OMW in the Jerash region.

“…Chrysosporium is one of the organisms whose ligninolytic enzyme system has been studied extensively. Because of its high ligninolytic activity, rapid growth, and ability to produce asexual spores, several biotechnological applications were tested using this particular species (Sayadi and Ellouz, 1992;1993).…”

“…A recent work has shown that the P. Chrysosporium species is able to degradate a wide variety of phenolic compounds (Sayadi and Ellouz, 1992;1993). Besides P. Chrysosporium produces two types of extra-cellular peroxidases involved in lignin biodegradation:…”

RESUMENLa biodegradación del alpechín por sawdust y por Phanerochaetae chrysosporium.Este trabajo describe la decoloración y la disminución de la demanda química de oxígeno del alpechín (OMW) por Phanerochaetae chrysosporium, crecido en cultivos estáti-cos, agitados e inmovilizados. Cuando P. chrysosporium fue cultivado en agitación, no se observa ninguna decoloración de OMW crudo, la decoloración ocurre solamente después de eliminar los polifenoles mediante adsorción en el serrín (Disminución del 39% del contenido en polifenoles). La utilización de la lignina peroxidasa generada en el medio da lugar a la mayor decoloración de alpechín y a las eficiencias de eliminación de DQO más altas. Las pruebas de la decoloración realizadas en las muestras de OMW que fueron pretratadas por la adsorción de madera del serrín, y usaron cultivos inmovilizadas demostraron resultados mejores. Por tanto, la eficiencia de eliminación de DQO alcanzó un 70%. La reducción de los polifenoles alcanzó los niveles más altos siempre, i.e. 62%. Se observó una decoloración significativa del efluente. PALABRAS-CLAVE: Alpechín -Biodegradación --Decoloración -Polifenoles -Serrín. SUMMARY The biodegradation of Olive Oil Mill Wastewaters by Sawdust and by a Phanerochaetae chrysosporium.This paper discusses decolorization and chemical oxygen demand (COD) abatement in olive mill wastewaters (OMW) by Phanerochaetae chrysosporium grown in static, stirred and immobilized cultures. When P. Chrysosporium is used in cultures, no decolorization of crude OMW is observed. Decolorization occurs only after the removal of polyphenols by adsorption in sawdust, which allows a 39% polyphenol removal. The use of a High lignin peroxides (Lip) producing medium, yields the highest OMW decolorization and COD removal efficiencies. The use of P. Chrysosporium immobilized on polyurethane foam leads to significant abatements of OMW polluting characteristics. And COD abatement reached 70%. The reduction of polyphenols reached its highest level at 62%. A significant effluent decolorization is apparent.
