Peroxidative phenol removal from aqueous solutions using activated peroxidase biocatalyst

Peroxidase mediated decolorization and remediation of wastewater containing industrial dyes: a review

“…Biological degradation of dyes included properties such as water solubility, large molecular weight (M r ) and fused aromatic ring structures, which inhibited permeation through biological cell membranes. Other limitations of using microbes for treating pollutants were high costs of production of microbial culture, slow process of decolorization/degradation of dyes and metabolic inhibition (Duran 2000;Husain and Jan 2000;Nazari et al 2007). Various organisms have been used for the complete degradation of aromatic compounds but much success has not been achieved yet.…”

Tyrosinase and peroxidase production by Rhizopus oryzae strain ENHE obtained from pentachlorophenol‐contaminated soil

“…8 -11 Peroxidase and laccase production by basidiomycetes has been reported by many authors, and it has been demonstrated that these enzymes are involved in chlorinated and aromatic compound degradation. 4,12 -14 The peroxidase reaction is H 2 O 2 -dependent, 15 while the oxidation of compounds by laccases requires co-substrates, generally oxidisable low-molecular-weight compounds called mediators. More than 100 possible mediator compounds have been described, but the most commonly used are 2,2 -azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 1-hydroxybenzothiazoline (HBT).…”

Electrocoagulation treatment of black liquor from soda-AQ pulping of wheat straw

“…The usual treatment methods used for pulp and paper mill wastewater are wet oxidation (Fox and Noike 2004), ozone treatment (Freire et al 2000), biological treatment (Clemente et al 2004), and adsorption (Shawwa et al 2001). Despite these effective treatments, there are disadvantages such as high operational costs and the use of chemicals as well as the production of more sludge (Nazari et al 2007).…”
