“…Indeed, when we magnetically separated the nanocomplex, the supernatant did not show significant catalysis as no visual color change was observed. We further studied the phenol removal efficiency by UV Vis monitoring at 280 nm [23]. After treatment with the nanocomplex and H 2 O 2 , the characteristic peak at 280 nm for phenol disappeared within 30 min and a new broad peak appeared at ~370 nm ( Fig.…”

We report a novel nanotechnology-based approach for the highly efficient catalytic oxidation of phenols and their removal from wastewater. We use a nanocomplex made of multi-walled carbon nanotubes (MWNTs) and magnetic nanoparticles (MNPs). This nanocomplex retains the magnetic properties of individual MNPs and can be effectively separated under an external magnetic fi eld. More importantly, the formation of the nanocomplex enhances the intrinsic peroxidase-like activity of the MNPs that can catalyze the reduction of hydrogen peroxide (H 2 O 2 ). Significantly, in the presence of H 2 O 2 , this nanocomplex catalyzes the oxidation of phenols with high effi ciency, generating insoluble polyaromatic products that can be readily separated from water.

“…In the presence of Fe(II), the AAD-12 protein catalyzes the conversion of dichlorphenoxyacetate to 2,4-dichlorophenol and glyoxylate concomitant with the decomposition of α-ketoglutarate to form succinate and carbon dioxide. The resulting phenol is measured with an AAPPC assay or the Emerson reaction (Emerson, 1943). All heating conditions eliminated the enzymatic activity of the AAD-12 protein.…”

USDA-APHIS Petition for Nonregulated Status of DAS-8191Ø-7 CottonPage 3 of 214 Dow AgroSciences LLC CertificationThe undersigned certifies that, to the best knowledge and belief of the undersigned, this petition includes all information and views on which to base a determination and that it includes all relevant data and information known to the petitioner, unfavorable as well as favorable, associated with DAS-8191Ø-7 cotton. SummaryDow AgroSciences LLC (herein referred to as "DAS") is submitting a Petition for Determination of Nonregulated Status for DAS-8191Ø-7 cotton. DAS requests from USDA Animal and Plant Health Inspection Service (APHIS) that cotton transformation event DAS-8191Ø-7 and any cotton lines derived from crosses between DAS-8191Ø-7 cotton and conventional cotton or biotechnology-derived cotton granted nonregulated status by APHIS, no longer be considered regulated articles under 7 CFR Part 340.DAS has developed transgenic cotton plants containing aad-12 and pat, which confer tolerance to the herbicides 2,4-dichlorophenoxyacetic acid (2,4-D) and glufosinate. DAS-8191Ø-7 cotton will provide growers with greater flexibility in selection of herbicides for the improved control of economically important weeds; allow an increased application window for effective weed control; and provide an effective weed resistance management solution to the growing incidence of glyphosate resistant weeds.DAS-8191Ø-7 cotton plants have been genetically modified to express aryloxyalkanoate dioxygenase-12 (AAD-12). AAD-12 is an enzyme with an alpha ketoglutarate-dependent dioxygenase activity which results in metabolic inactivation of the herbi...
