“…(Giannoutsou et al 2004; Table 4). In contradiction to the general relationship between phenolic content reduction and phytotoxicity reduction, Tsioulpas et al (2002) reported that different strains of Pleurotus spp. were able to remove phenolics from OMWW but suggested that the remaining phenolics and/or some of the oxidation products of the laccase reaction were more toxic than the original phenolic mixture.…”

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.

“…From an environmental point of view, OMWW is an environmental emergency as it has a considerable polluting organic load, with a maximum biological oxygen demand and chemical oxygen demand of about 100 and 220 kg·m -3 , respectively, an average concentrations of volatile solids and inorganic matter of 15% and 2%, respectively, and organic matter fraction that includes sugars, tannins, polyphenols, polyalcohols, pectins and lipids [5]. Therefore, a series of studies focused on the degradation of OMWW and its chemical components [5][6][7][8], and many authors used specific microorganisms for OMWW treatment [9][10][11][12][13]. Microbiological and physicochemical parameters were used as indicators to study the kinetic of OMWW biodegradation, such as chemical oxygen demand (COD), dissolved organic carbon, counts of heterotrophs, filamentous fungi, and yeasts, and content of K, P and N [8][9][10][11][12][13][14].…”

Some authors obtained satisfactory results, in terms of OMWW degradation and amelioration of soil physicochemical properties, by adding this liquid waste to agro-industrial and urban wastes and monitoring the physicochemical parameters during the composting process of these matrices [16][17][18].…”

Different mixtures of olive pomace (OP), olive mill wastewater (OMWW) and olive pruning residues (OPR) were aerobically co-composted under natural conditions. Compost temperature showed a sharp increase in the first 40 -60 days, followed by a stabilization at 60°C and a decline after 150 days, whereas compost water content ranged from 50% -55% to 25% -30%. Total and selective microbial counts were followed throughout the experiment by means of innovative (IMT) and conventional (CMT) microbiological techniques. Pseudomonas spp., anaerobic bacteria, actinomycetes, and fungi reached levels of 8, 7, 5 and 6 log CFU g -1 compost, respectively, with a slight depression after 30-80 days. Total and fecal coliforms strongly decreased during the composting process. The use of IMT allowed to detect a higher and more stable growth of microorganisms if compared to CMT. IMT was demonstrated to be an appropriate and reliable method for monitoring the microbial pools during the co-composting process.

Les techniques de traitement de la margine pratiquées par les pays producteurs d'huile d'olives (Tunisie, Maroc, Italie…) telles que le traitement par lagunage, le traitement par électrocoagulation et le traitement électrochimique, sont orientées vers la dégradation des composés phénoliques pour réduire leur DCO (demande chimique en oxygène) et leur DBO5 (demande biologique en oxygène). Notre travail constitue un nouvel axe de recherche puisqu'il rentre dans le cadre de la mise au point d'un procédé de récupération de produits valorisables présents dans la margine. Il vise à identifier les composés phénoliques à hautes valeurs commerciales après séparation par trois techniques (extraction, distillation fractionnée et entrainement à la vapeur d'eau), suivies des analyses par chromatographie couplée à la spectrométrie de masse. Ces analyses ont permis de déterminer la teneur de ces composés dans deux qualités de margine de nature et de provenance différentes.
