Evaluation of a New Laccase Produced by Streptomyces Ipomoea on Biobleaching and Ageing of Kraft Pulps
The aim of this work is to prove the suitability of a new alkaline and halotolerant bacterial laccase (SilA) produced by Streptomyces ipomoea CECT 3341 to enhance the conventional chemical bleaching process of an industrial eucalyptus kraft pulp. The laccase used for this study was a recombinant laccase obtained from cultures of E. coli BL21 (DE3) grown in LB liquid medium. The biobleaching exp...
متن کاملdegradation of oil impregnated paper insulation under influence of repetitive fast high voltage impulses
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 اولBiobleaching 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...
متن کاملMediators in biobleaching of pulps by laccases
Laccases oxidize variety of aromatic and non aromatic compounds by using oxygen as the electron acceptor and producing water as by-product. Generally laccases need mediators for catalyzing the removal of lignin from pulp. The potential of laccase mediator system (LMS) to degrade lignin polymer has been demonstrated by many researchers, but still the high cost and possible toxicity of artificial...
