Role of Lignin Peroxidase and Manganese Peroxidase of Phanerochaete Chrysosporium in the Decolorization of Olive Mill Wastewaters

Relationship between cultivation mode of white rot fungi and their efficiency for olive oil mill wastewaters treatment

“…This corroborates previous observations (Sayadi and Ellouz, 1995) for P. chrysosporium and for C. polyzona (Jaouani et al 2005). In the case of P. coccineus, growing in the form of free mycelium, and C. polyzona in solid state form, we have observed new peaks corresponding to intermediate molecular masses, possibly originating from partial depolymerisation of the heavy polyphenols fraction and/or laccase mediated partial repolymerisation of low molecular mass phenolics (Jaouani et al 2005).…”

“…An interesting feature shared by all the studied fungi is their capacity to decolourize and degrade phenolics without any supplementation of the OOMW based medium. This was previously reported for certain strains; in particular P. chrysosporium (Kissi et al 2001;Sayadi and Ellouz, 1995). This could however result from the origin of the strain and/or the OOMW.…”

“…A lot of data were obtained concerning treatment of pulp and paper, (Kondo et al 1994;Taspinar and Kolankaya, 1998;De Souza-Cruz et al 2004;Gamelas et al 2005), dyes and textile (Lucas et al 2008), oxidation of polycyclic aromatic hydrocarbons (Zheng and Obbard, 2002) and OOMW (Sayadi and Ellouz, 1995;Jaouani et al 2005). Yet, the research domain often suffered from difficulty of comparison between the published information, mainly because of the use of different cultivation procedures by different authors, and even in several cases poor description of cultivation mode.…”

“…Although, apparently not detected in the present investigation (not illustrated), the role of other enzymes, including Lignin peroxidase, Manganese peroxidase (Kondo et al 1994;Belinky et al 2003;Songulashvili et al 2007) and cellobiose dehydrogenase should be also evaluated in more details. For example, Sayadi and Ellouz (1995) reported a possible role for Lignin Peroxydase and Manganese Peroxydase from Phanerochaete chrysosporium in the decolourization of OOMW. Aissam et al (2005) have detected a Manganese peroxidase activity produced by a Aspergillus niger strain degrading polyphenols in OOMW.…”

Mechanistic studies on the effect of veratryl alcohol on the lignin peroxidase catalyzed oxidation of pyrogallol red in reversed micelles

“…The use of white rot fungi, such as Phanerochaete chrysosporium, in the degradation of environmental pollutants is a hot topic in the field of environmental science and engi-neering [1][2][3][4][5][6][7]. Their ability to degrade aromatic pollutants comes from the extracellular enzymes produced under ligninolytic conditions, such as lignin peroxidase (LiP) [8][9][10][11][12][13][14][15][16][17].…”
