Light-Dependent Aerobic Methane Oxidation Reduces Methane Emissions from Seasonally Stratified Lakes
Lakes are a natural source of methane to the atmosphere and contribute significantly to total emissions compared to the oceans. Controls on methane emissions from lake surfaces, particularly biotic processes within anoxic hypolimnia, are only partially understood. Here we investigated biological methane oxidation in the water column of the seasonally stratified Lake Rotsee. A zone of methane ox...
Oxidation of Cr(III) and reduction of Cr(VI) can occur simultaneously in aerobic soils, but the mechanisms involved are not well-understood, especially how electron shuttling by redox-active organic acids is involved. A and B soil horizons from three topohydrosequences from the Coastal Plain and Piedmont physiographic provinces of Maryland were chosen to investigate oxidation-reduction transfor...
Aerobic capacity/fitness significantly impacts susceptibility for fatty liver and diabetes, but the mechanisms remain unknown. Herein, we utilized rats selectively bred for high (HCR) and low (LCR) intrinsic aerobic capacity to examine the mechanisms by which aerobic capacity impacts metabolic vulnerability for fatty liver following a 3-day high-fat diet (HFD). Indirect calorimetry assessment o...
We have recently proposed the existence of a bacteriocolonic pathway for ethanol oxidation [i.e., ethanol is oxidized by alcohol dehydrogenases (ADHs) of intestinal bacteria resulting in high intracolonic levels of reactive and toxic acetaldehyde]. The aim of this in vitro study was to characterize further ADH activity of some aerobic bacteria, representing the normal human colonic flora. These...
We have previously described the rates of oxidation for long-chain fatty acids and glucose in stunned myocardium during early reflow after moderately severe regional ischemia. The purpose of these studies was to characterize the rates of pyruvate and lactate oxidation during comparable periods of reflow. In the main protocol, pyruvate oxidation was defined at two conditions of coronary flow and...
During a study of cyclic alcohol oxidation by a partially purified rat liver enzyme system (l), it was noted that ethanol was also oxidized by this preparation. Since the ratio of the rate of ethanol oxidation to the rate of cyclohexanol oxidation remained constant during purification, the possibility arose that the activity with cyclic substrates was due to the conventional alcohol dehydrogena...
