“…For the waste waters treatment have been proposed both physic-chemical and biological processes (Amirante & Di Rienzo, 1993;McNamara et al, 2008;Rozzi & Malpei, 1996;Vigo et al, 1990;Vitolo et al, 1999).…”

“…The concentration of phenolic compounds in OMW may reach 5 g L -1 to 10 g L -1 due to higher solubility in the water phase than oil (10)(11)(12). The types and concentrations of phenolic compounds in OMW vary tremendously with region, type of used process, conditions of everyday use, and local operational procedure (13). More than 30 different phenolic compounds have been identifi ed in OMW: monocyclic aromatic molecules such as hydroxytyrosol, tyrosol, catechol, methylcatechol, caffeic acid, and compounds with greater molecule mass obtained by their polymerisation (12,14,15).…”

“…In the past two decades, many processes have been investigated in order to reduce the toxicity of OMW and to use it as food or raw material in various biotechnological processes (1,13,17,18). Treatment and reuse of OMW presents signifi cant challenges both due to the nature of olive oil production and due to the characteristics of the wastewater (high COD, high phenolic content, and dark colour) (13).…”

“…Biological processes investigated for OMW treatment are aerobic and anaerobic (6)(7)(8)(9)(10)(11). The major problem with anaerobic processes is the inhibition of anaerobic microorganisms by phenolic compounds and long-chain fatty acids present in OMW and their persistence in effl uent (13). A build up of recalcitrant phenolics such as condensed tannins is also reported (19).…”

Olive oil production generates large volumes of wastewater. These wastewaters are characterised by high chemical oxygen demand (COD), high content of microbial growth-inhibiting compounds such as phenolic compounds and tannins, and dark colour. The aim of this study was to investigate biodegradation of olive mill wastewater (OMW) by yeasts Trichosporon cutaneum and Geotrichum candidum. The yeast Trichosporon cutaneum was used because it has a high potential to biodegrade phenolic compounds and a wide range of toxic compounds. The yeast Geotrichum candidum was used to see how successful it is in biodegrading compounds that give the dark colour to the wastewater. Under aerobic conditions, Trichosporon cutaneum removed 88 % of COD and 64 % of phenolic compounds, while the dark colour remained. Geotrichum candidum grown in static conditions reduced COD and colour further by 77 % and 47 %, respectively. This investigation has shown that Trichosporon cutaneum under aerobic conditions and Geotrichum candidum under facultative anaerobic conditions could be used successfully in a two-step biodegradation process. Further investigation of OMW treatment by selected yeasts should contribute to better understanding of biodegradation and decolourisation and should include ecotoxicological evaluation of the treated OMW.

The industrial process of olive oil extraction produces huge amounts of wastes that have great negative impact on the environment, because of their high phytotoxicity against soil micro‐organisms and aquatic life. Valorization of olive mill waste water (OMWW) presents significant challenges mainly due to the high phenolic content of the wastewater which leads to high chemical oxygen demand (COD) and dark color. There is an insistent requirement for strategies to control these wastes through technologies able to minimize their negative environmental effect and to convert them to sustainable resources. Different micro‐organisms and techniques have been tested to valorize OMWW. This review, after presenting a general overview, focuses critically on the most significant recent advances in the various types of biological valorization techniques of OMWW. © 2013 Society of Chemical Industry and John Wiley & Sons, Ltd
