Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Degradation and induction specificity in actinomycetes that degrade p-nitrophenol [PDF]

Applied and Environmental Microbiology, 1993
We have isolated two soil bacteria (identified as Arthrobacter aurescens TW17 and Nocardia sp. strain TW2) capable of degrading p-nitrophenol (PNP) and numerous other phenolic compounds. A. aurescens TW17 contains a large plasmid which correlated with the PNP degradation phenotype. Degradation of PNP by A.

Magnetic lipase B from Candida antarctica (CALB) biocatalyst for integrated valorization of tilapia by‐products and biodiesel biorefining

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The immobilization of lipase B from Candida antarctica (CALB) on an amino‐epoxy functionalized magnetic support (Fe3O4‐PEI‐DGEBA) resulted in a highly stable and efficient biocatalyst for biofuel production from tilapia oil. The synthesized support was characterized using scanning electron microscopy, transmission electron microscopy, X‐ray ...

Inhibition of dehydrogenase activity in petroleum refinery wastewater bacteria by phenolic compounds

Revista Ambiente & Água, 2010
The toxicity of phenol, 2-nitrophenol, 4-nitrophenol, 2,4-dinitrophenol, 2-chlorophenol, 4-chlorophenol, 4-bromophenol and 3,5-dimethylphenol on Pseudomonas, Bacillus and Escherichia species isolated from petroleum refinery wastewater was assessed via ...

Application of near infrared spectroscopy for the determination of adsorbed p-nitrophenol on HDTMA organoclay –implications for the removal of organic pollutants from water

, 2008
NIR spectroscopy has been used to measure the adsorption of p-nitrophenol on untreated montmorillonite and surfactant exchanged montmorillonite. P-nitrophenol is characterised by an intense NIR band at 8890 cm-1 which shifts to 8840 cm-1 upon adsorption ...

Physiologically‐based pharmacokinetic modelling of uridine 5′‐diphosphoglucorosultransferase (UGT) substrate drugs in pregnant women

British Journal of Clinical Pharmacology, EarlyView.
Aims While pregnancy‐related changes in phase I enzyme activity are well‐documented, less is known about the impact on phase II enzymes. This study aimed to test the hypothesis that changes in the pharmacokinetics (PK) of uridine 5′‐diphosphoglucuronosyltransferase (UGT) substrates during pregnancy result from altered enzyme expression or activity ...

A STUDY OF THE HYDROGEN BONDING IN o-NITROPHENOL IN PRESENCE OF p-NITROPHENOL

, 1958
The individual polarograms of o- and \(p\)-nitrophenols in the \(p\)H range of 1.0 to 10.2 have been studied. The polarograms of mixtures of the two phenols at PH 10.2 and 2.0 have also been studied.

High‐performance tetrahedral palladium nanocatalyst for microwave‐assisted organic synthesis

Bulletin of the Korean Chemical Society, EarlyView.
Tetrahedral palladium nanoparticles anchored on graphene sheets (T‐Pd/graphene) were synthesized through a solvent‐free process involving thermal decomposition in an environment rich in carbon monoxide at elevated temperatures and have high catalytic activity for organic chemistry reactions. Abstract Palladium is widely recognized for its effectiveness

Comparative Adsorption of Nitrophenols on Macroporous Resin and Newly-Synthesized Hypercrosslinked Resin

Adsorption Science & Technology, 2003
The comparative adsorption of o -nitrophenol, m -nitrophenol and p- nitrophenol onto a macroporous polymeric adsorbent (Amberlite XAD-4) and a hypercrosslinked polymeric adsorbent (NJ-8) was investigated. Adsorption equilibrium isotherms were measured by

Synthesis of p-aminophenol by catalytic hydrogenation of p-nitrophenol

, 2003
The catalytic hydrogenation of p-nitrophenol to p-aminophenol was investigated in a laboratory-scale batch-slurry reactor. Pt/C catalyst (1%) was chosen for optimization of reaction conditions and kinetic studies because of its higher catalytic activity ...
