Lentinula edodes removes phenols from olive-mill wastewater: impact on durum wheat (Triticum durum Desf.) germinability

High level of laccases production by Trametes trogii culture on olive mill wastewater‐based media, application in textile dye decolorization

“…1,2 The annual production of OMW in the Mediterranean region reaches 30 million m 3 and about 1 million m 3 in Tunisia alone. 3 This waste is rich in water (80%), minerals (2%) and refractory organic compounds (4-16%) such as sugars, phenols, tannins, alcohols, pectin and lipids, which make it potentially appropriate for use as culture medium. 4 -6 Fortunately, white rot fungi (WRF) are known to be able to overcome the OMW toxicity and to secrete extra-cellular enzymes such as peroxidases and laccases that break down these phenolics.…”

Degradation of phenols in olive oil mill wastewater by biological, enzymatic, and photo-Fenton oxidation

“…The objective of this work was to assess the efficiency of the three different treatment strategies for removing phenols (p-coumaric acid, vanillin, guaiacol, caffeic acid, vanillic acid, and tyrosol) in OOMW, thus decreasing its potential toxicity since phytotoxic effects of olive residues can be attributed mainly to their content in phenolic compounds (D'Annibale et al 2004). Biological treatment by two fungal species (T. versicolor and Pleurotus sajor caju), enzymatic treatment by purified laccase, and chemical treatment by photo-Fenton oxidation were the experimental approaches applied on OOMW and in OOMW supplemented with extra concentration of each phenol.…”

Effect of olive mill wastewater on growth and bulb production of tulip plants infected by bulb diseases

“…However, apart from its antimicrobial properties, OMW may become phytotoxic (Bonari et al, 1993;Capasso et al, 1995), since uncontrolled OMW ap-plication could inhibit seed germination (Casa et al, 2003;D'Annibale et al, 2004), shoot and root elongation and biomass production (Asfi et al, 2012), plant growth (Ouzounidou et al, 2010), uptake and translocation of nutrients (Ouzounidou et al, 2008) and cause various physiological changes (Mekki et al, 2006;Ouzounidou et al, 2008;El Hassani et al, 2010) including decreased water use efficiency mainly due to decreased CO 2 assimilation rate (Asfi et al, 2012). The presence of phenols as well as short and long-chain fatty acids is believed to contribute to the phytotoxic nature of OMW (Casa et al, 2003;Kistner et al, 2004;Isidori et al, 2005).…”
