Potential use of oxidative enzymes for the detoxification of organic pollutants

Catalytic and kinetic properties of purified Eichhornia crassipes leaf peroxidase

“…However, studies are still ongoing to identify peroxidases from other sources with properties suitable for biotechnological, biomedical and other industrial applications (Regalado et al 2004). Some peroxidases from these sources have shown potential for applications as biocatalysts and bioelectrocatalysts (Adam et al 1999;Torres et al 2003;Carlos et al 2005).…”

Extracellular Laccase Produced by an Edible Basidiomycetous Mushroom,Grifola frondosa: Purification and Characterization

“…18,19) In addition to physiological functions, due to their broad substrate specificity, laccases have the unique ability to oxidize a broad range of xenobiotic compounds, such as synthetic dyes, 20) pesticides, 21) and chlorinated phenolics. 22) Hence, they have attracted considerable interest for application in many fields of industrial and environmental processes, including paper pulping and bleaching, 23,24) textile dye bleaching, 25) bioremediation, 26) and effluent detoxification.…”

Fungal Bioremediation of Emerging Micropollutants in Municipal Wastewaters

“…A promising alternative could be represented by the direct use of fungal crude extract or by purified enzymes capable of maintaining the catalytic yields of the fungal cultures, with less technical drawbacks (Torres et al 2003). The use of purified enzymes poses some concerns for environmental purposes; without other enzymatic isoforms and fungal metabolites, their catalytic efficiency and stability could be compromised.…”

“…A detailed evaluation of risks and benefits is necessary carefully considering several factors: mediators have a cost, may be toxic and need to be regenerated in the system, too (Kunamneni et al 2008, Torres 2003. Moreover, in some cases, the oxidized radicals can destabilize the enzymes, leading to irreversible inactivation (Kunamneni et al 2008).…”
