Treatment of 2,4-dichlorophenol using soybean peroxidase.
In the presence of hydrogen peroxide (H2O2), soybean peroxidase (SBP) extracted from the soybean seed coat catalyzes the polymerization of various chlorinated phenols from wastewater. The resulting polymer precipitates from solution and can be removed through a simple sedimentation or filtration …

Effect of 2,4-dichlorophenol on biological model membranes
… of cell membranes in the presence of 2,4-dichlorophenol (DCP) using following methodes: differential scanning calorimetry (DSC), small- (SAXS) and wide-angle X-ray scattering (WAXS), freeze-fracture/TEM and FT-Raman spectroscopy. The results suggested that the effect of DCP on the …

Anaerobic biodegradation of selected organic compounds with and without inhibition of sulfate reducing bacteria
… ether (MTBE), toluene, phenol, and 2,4- dichlorophenol. In addition, biodegradation rates of these compounds at various initial concentrations with and without inhibition of sulfate reducing bacteria were determined along with anaerobic biodegradation rate constants for each of the …

The Mechanisms, Products, and Kinetics of Triclosan-Free Chlorine Reactions
… on mass spectral analysis. Additionally, 2,4-dichlorophenol, 2,4,6-trichlorophenol, and chloroform formed under excess free chlorine conditions. The majority of the chloroform formed during the reactions does not form via 2,4-dichlorophenol and 2,4,6-trichlorophenol oxidation. Therefore, the …

The fathead minnow embryo as a model for the development of alternative testing methods in ecotoxicology.
… zebrafish (ZFET) and a substi-tuted phenol (2,4-dichlorophenol). Fathead minnow embryos proved to be slightly less sensi-tive for cadmium chloride and clearly less sensitive for 3,4-dichloroaniline than adult fathead minnow (OECD TG 203), whereas for 2,4-dichlorophenol no difference in …

Effect of the fractionation and immobilization on the sorption properties of humanic acid
… and humic acid, on the sorption behavior of 2,4-dichlorophenol under laboratory conditions selected to model the soil systems. Humic acid is very heterogeneous in terms of physical and chemical properties. To reduce the chemical heterogeneity of the extracted humic acid (from the Ap horizon of …

Quantitative Erfassung von Bakterien und deren spezifische Aktivität in komplexen Habitaten mittels Fluoreszenzmikroskopie und digitaler Bildverarbeitung
… B: Ralstonia eutropha JMP134-1, 2,4-Dichlorophenol and Dodecltrimethylammonium+ modified Mont-morillonit). In both model systems, slight changes in bacterial concentrations were successfully determined in the presence of clay minerals.

Electrochemical dynamics of cytochrome P450-3A4 isoenzyme biosensor for protease inhibitor antiretroviral drug
… 1 was evaluated for the detection of 2,4-dichlorophenol, whereas biosensor platform 2 was evaluated for the detection of protease inhibitor (PI) HAART drug, indinavir. Fourthly, this dissertation also reports on the use of genetic engineering as complimentary method during biosensor …

Formation of Chloroform and Other Chlorinated Byproducts by the Chlorination of Antibacterial Products
… detected included (chlorophenoxy)phenols, 2,4-dichlorophenol, 2,4,6-trichlorophenol, and chloroform. The daughter product yields were found to be highly variable and were dependent on the antimicrobial product investigated, the free chlorine to triclosan ratio, and the temperature at which the …

Evaluation of Triclosan Reactivity in Monochloraminated Waters
… three chlorinated triclosan intermediates, 2,4-dichlorophenol, and 2,4,6-trichlorophenol. Low levels of chloroform were detected at pH values of 6.5 and 7.5.

Biodegradation of organic contaminants in subsurface systems: kinetic and metabolic considerations
… l-butanol, TBA, pentanol, phenol and 2,4-dichlorophenol; describe site specific conditions which enhance or inhibit degradation and compare biodegradation rates with thermodynamic predictions. Laboratory microcosms utilizing soil from two previously uncontaminated sites of widely varying …

Investigation of the Interactions Among Grass, Chlorophenols and Microbes
… interactions between live grasses and 2,4-dichlorophenol (DCP), 2,4,6-trichlorophenol (TCP), and pentachlorophenol (PCP); physico-chemical interactions between the three chlorophenols and root tissue; and effect of root exudates on biodegradation of TCP. To study the interactions between …
