Electrolytic production of hydrogen peroxide
… factors affecting the electrolytic production of hydrogen peroxide from hydrogen and oxygen. The mechanism of this reaction throws light on the production and chemistry of hydrogen peroxide, electrochemistry of hydrogen, oxygen and water and the mechanism of corrosion. This investigation involved …

Intracellular Dynamics of Hydrogen Peroxide in Escherichia Coli
Surprisingly, additional experiments utilizing these scavenger-less mutants confirmed that the majority of endogenous H2O2 does not appear to be a result of the electron transport chain. However, these results did confirm that specific flavoenzymes, shown in vitro to make H 2O2, can autoxidize and …

The reaction between ferrocytochrome c and hydrogen peroxide
The reaction between ferrocytochrome c and hydrogen peroxide has been studied to determine possible reaction mechanisms. This was done by investigating the effect of various physical factors, such as hydrogen ion concentration, ionic strength and temperature, on the reaction and by studying the …

Production and Decomposition of Hydrogen Peroxide by Marine Phytoplankton
<p>H<sub>2</sub>0<sub>2</sub> in seawater has complicated sources and sinks. The relative importance of biological regulation of H<sub>2</sub>0<sub>2</sub> compared to other processes is not well understood. In addition, environmental factors affecting the biological regulation of H202 are largely …

Application of hydrogen peroxide as brown tide bloom control agent
… the potential of natural chemical biocide hydrogen peroxide (H_2O_2) as a reagent to serve the purpose. Studies on laboratory cultures were carried out in order to determine the effectiveness of H_2O_2 at eradicating A. anophagefferens. Then, the safety (to non-target organisms) and …

Higher order chromatin degradation induced by hydrogen peroxide in glial cells
… in cultured rat oligodendrocytes by exposure to hydrogen peroxide (H2O2). Intact genomic DNA was isolated by agarose embedding and its fragmentation was assessed by field inversion gel electrophoresis (FIGE). To detect single strand fragmentations, the DNA was digested with S1 nuclease before …

The mechanism by which manganese protects Escherichia coli from hydrogen peroxide
… that manganese does so by chemically scavenging hydrogen peroxide and/or superoxide .We found that manganese does not protect peroxide-stressed cells by scavenging peroxide. Instead, the beneficial effects of manganese correlate with its ability to metallate mononuclear enzymes. Because …
