Green 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 کاملConditions 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...

در طی سالهای اخیراستفاده ازمنابع انرژی تجدید پذیر در شبکه های مدرن بنا به دلایل زیست محیطی و اقتصادی به طور گسترده استفاده شده است همچون نیروگاههای بادی و خورشیدی .ولتاژتولیدی این نیروگاهها اغلب به فرم dc می باشد وادوات الکترونیک قدرت به عنوان مبدل و پل بین شکل موج dc وac استفاده می شوند.این پروسه باعث ایجاد پالسهایی برروی شکل موج خروجی می شود که می تواند وارد تجهیزات قدرت همچون ترانسفورماتور ی...
15 صفحه اولDecolorization of Solophenyl Red 3BL Polyazo Dye by Laccase-Mediator System: Optimization through Response Surface Methodology
The decolorization of direct Solophenyl red 3BL (SR), a polyazo dye extensively used in textile industry was studied. The Fomes fomentarius laccase alone did not decolorize SR. The natural redox mediator, acetosyringone (AS), was necessary for decolorization to occur. Box-Behnken design was used to evaluate the effects of three parameters, namely, enzyme concentration (0.5-2.5 U mL(-1)), redox ...
