A metabolic model for thiodiglycol degradation: capacity constraint leads to byproduct accumulation

Bioprocess and Biosystems Engineering, 2001
A metabolic model was developed to describe the degradation of thiodiglycol (TDG) by Alcaligenes xylosoxydans ssp. xylosoxydans (SH91). Experimental evidence has suggested there is a metabolic capacity constraint that limits the specific thiodiglycol utilization rate, leads to metabolic byproducts, and ultimately inhibits the overall degradation ...

Electrochemical degradation of neutral red on PbO2/α-Al2O3 composite electrodes: Electrode characterization, byproducts and degradation mechanism

Separation and Purification Technology, 2019
Abstract PbO2/α-Al2O3 composite electrodes were successfully synthesized using composite electrodeposition technology and applied for the electrocatalytic degradation of neutral red (NR). The effect of α-Al2O3 particles on the surface morphology, structure, stability and electrochemical properties of PbO2/α-Al2O3 composite electrodes were ...

Evaluating Macrophage Immune Response to Degradation Byproducts from Magnesium Alloy Wire

2025 Design of Medical Devices Conference
Abstract Magnesium alloys have recently gained increasing attention for biomedical applications due to their unique biodegradation and biocompatibility profiles. However, investigations of the interactions between magnesium alloy degradation byproducts and host immune cells (particularly macrophages) are still relatively unexplored. Here,

Free-Radical Chemistry of Disinfection Byproducts. 3. Degradation Mechanisms of Chloronitromethane, Bromonitromethane, and Dichloronitromethane

The Journal of Physical Chemistry A, 2009
Halonitromethanes (HNMs) are byproducts formed through ozonation and chlorine/ chloramine disinfection processes in drinking waters that contain dissolved organic matter and bromide ions. These species occur at low concentration but have been determined to have high cytotoxicity and mutagenicity and therefore may represent a human health hazard.

Chlorination of enoxacin (ENO) in the drinking water distribution system: Degradation, byproducts, and toxicity

Science of The Total Environment, 2019
Chlorine is widely used as a drinking water disinfectant to ensure water security. However, the transformation mechanisms of its degradation of emerging pollutants within the water distribution system (WDS) is insufficiently understood. Thus, the kinetics, degradation byproducts, and toxicity of the chlorination of enoxacin (ENO, a type of emerging ...

Thermo-activated periodate oxidation process for tetracycline degradation: Kinetics and byproducts transformation pathways

Journal of Hazardous Materials
Periodate-based advanced oxidation processes have been diffusely practiced for pollutant decontamination. However, the thermo-activation of periodate process (heat/PI), an effective water pollution removal process, has been rarely discussed, and the degradation pathway of this heat/PI system requires investigation.

Heat-treated timber: potentially toxic byproducts presence and extent of wood cell wall degradation

Holz als Roh- und Werkstoff, 2000
C NMR to determine which type of loose chemical compounds were produced by the thermal treatment. The formation of some toxic polynuclear aromatic hydrocarbons derivatives of phenantrene as well as other classes of polyaromatics compounds was detected.

Photolytic degradation of ciprofloxacin in solid and aqueous environments: kinetics, phototransformation pathways, and byproducts

Environmental Science and Pollution Research, 2017
Many lipophilic pharmaceuticals may be sorbed in solid phases, leading to different photochemical behaviors. This study investigated the photochemistry of ciprofloxacin in a solid-phase system and compared it to that in a water-phase system. Kaolinite was used as the model solid matrix.

Degradation kinetics, byproducts formation and estimated toxicity of metronidazole (MNZ) during chlor(am)ination

Chemosphere, 2019
The residues of pharmaceuticals and personal care products (PPCPs) in environmental waters have been widespread concerned. Metronidazole (MNZ), normally employed to treat inflammation and infection, was chosen as one model PPCP. The degradation of MNZ by chlorination could be fitted by pseudo-first-order kinetics as the observed pseudo-first-order rate ...
