New Synthesis of Polyaniline using a Peroxides Enzyme
A new method for the synthesis of water soluble Polyaniline (PANi) using Hemin Chloride (H.C) in the presence of hydrogen peroxide (H.P) is presented. Hemin chloride is an effective catalyst for the oxidative polymerization of aniline in the presence of hydrogen peroxide at room temperature. The UV- Vis absorption spectra of the product show a distinct absorption peak at 430 nm in pH 4.0 b...
متن کاملMonooxygenase, a Novel Beta-Cypermethrin Degrading Enzyme from Streptomyces sp
The widely used insecticide beta-cypermethrin has become a public concern because of its environmental contamination and toxic effects on mammals. In this study, a novel beta-cypermethrin degrading enzyme designated as CMO was purified to apparent homogeneity from a Streptomyces sp. isolate capable of utilizing beta-cypermethrin as a growth substrate. The native enzyme showed a monomeric struct...
متن کاملa review on engineering of organophosphorus hydrolase (oph) enzyme
organophosphorus chemicals are compounds which have been used as pesticides and insecticides in agriculture. they’re also used as nervous agents and have raised many problems for human and environment. among the most important methods of decontamination from these compounds are biodegradation methods. using oph enzyme in degradation the mentioned compounds is seen as one of the desirable ways, ...
متن کاملInfluence of a Novel Magnetic Recoverable Support on Kinetic, Stability and Activity of Beta-amylase Enzyme
In this paper, covalent immobilization of beta amylase enzyme on the surface of modified magnetic nano particles (ZnFe2O4@SiO2-NH2) is reported. For doing so, at first, the magnetic nanoparticles of ZnFe2O4 were synthesized by chemical co-precipitation method and then tetraethyl orthosilicate (TEOS) and 3-aminopropyltriethoxy sil...
متن کاملRubber-degrading enzyme from a bacterial culture.
Rubber-degrading activity was found in the extracellular culture medium of Xanthomonas sp. strain 35Y which was grown on natural rubber latex. Natural rubber in the latex state was degraded by the crude enzyme, and two fractions were separately observed by gel permeation chromatography of the reaction products. One fraction was of higher molecular weight (HMW) with a very wide MW distribution f...
