Conditions Optimizing and Application of Laccase-mediator System (LMS) for the Laccase-catalyzed Pesticide Degradation
A high capacity of laccase from Trametes versicolor capable of degrading pesticides has been revealed. The conditions for degrading of five selected pesticides including chlorpyrifos, chlorothalonil, pyrimethanil, atrazine and isoproturon with the purified laccases from Trametes versicolor were optimized. The results showed that the optimum conditions for the highest activity were pH at 5.0 and...
متن کاملGreen oxidations with laccase-mediator systems.
Laccases are oxidase enzymes produced by 'white rot' fungi as part of a complex armoury of redox enzymes used to break down lignin--part of the carbon cycle of nature. Laccases alone or in combination with redox co-catalysts have been shown to oxidize xenobiotic compounds under conditions that can be described as 'green'. This paper describes some novel oxidations using the laccase-mediator met...
متن کاملLignin Biodegradation with Laccase-Mediator Systems
*Correspondence: Lew Paul Christopher , Center for Bioprocessing Research and Development, South Dakota School of Mines & Technology, 501 E. Saint Joseph Street, Rapid City, SD 57001, USA e-mail: [email protected] Lignin has a significant and largely unrealized potential as a source for the sustainable production of fuels and bulk high-value chemicals. It can replace fossil-based oil as...
متن کاملLaccase/Mediator Systems: Their Reactivity toward Phenolic Lignin Structures
Laccase-mediator systems (LMS) have been widely studied for their capacity to oxidize the nonphenolic subunits of lignin (70-90% of the polymer). The phenolic subunits (10-30% of the polymer), which can also be oxidized without mediators, have received considerably less attention. Consequently, it remains unclear to what extent the presence of a mediator influences the reactions of the phenolic...
متن کاملBiobleaching of Orange Tree Pruning Cellulose Pulp with Xylanase and Laccase Mediator Systems
The biobleachability of soda-anthraquinone pulp from orange tree pruning has been evaluated in this study for the first time. Three different laccase-mediator systems (LMS) have been tested: laccase from Trametes villosa (Tv), either in combination with 1-hydroxybenzotriazole (HBT) or with acetosyringone (AS), and laccase from Myceliophthora thermophila (Mt) in combination with AS. After the LM...
