Degradation of azo dyes by oxidative processes – Laccase and ultrasound treatment

Enzyme-catalyzed production of biodiesel by ultrasound-assisted ethanolysis of soybean oil in solvent-free system

“…Different from the traditional inactivation by the high temperatures, the sonication process does not affect the active sites of the enzyme. This observation has already been demonstrated for a-amylase, peroxidase, lacase and alkaline-phosphatase [34,35].…”

Ligninolytic Enzymes for Water Depollution, Coal Breakdown, and Paper Industry

“…The degradation ability of the organisms also depends on the oxidation potential of the dye (Tauber et al 2008). Biosorption of the dyes is also a promising technique which will enhance the color removal of the effluent steam containing a mixture of dye.…”

Industrial Wastewater Treatment: A Challenging Task in the Industrial Waste Management

“…In the recent years, the studies that dealt with the partial pre-oxidation of myriads of dye wastewater reported the involvement of all kinds of PDO. Some of these studies included the partial oxidation ozonation, H 2 O 2 photocatalysis, photography -Fenton moist air oxidation combined with photocatalysis and ozonation/H 2 O 2 , photo-electrochemical process [6] under oxidation, and water and supercritical electron beam bulk of treatment [140]. These studies reported on the improvement of the biodegradability and the reduction of toxicity following PDO treatment without the biological reactor.…”
