Anaerobic Formate and Hydrogen Metabolism

EcoSal Plus, 2016
Numerous recent developments in the biochemistry, molecular biology, and physiology of formate and H 2 metabolism and of the [NiFe]-hydrogenase (Hyd) cofactor biosynthetic machinery are highlighted. Formate export and import by the aquaporin-like pentameric formate channel FocA is governed by interaction with ...

Glycine metabolism in anaerobes

Antonie van Leeuwenhoek, 1994
Some strict anaerobic bacteria catalyze with glycine as substrate an internal Stickland reaction by which glycine serves as electron donor being oxidized by glycine-cleavage system or as electron acceptor being reduced by glycine reductase. In both cases, energy is conserved by substrate level phosphorylation.

Lipid Metabolism in Anaerobic Ecosystems

Critical Reviews in Microbiology, 1991
In anaerobic ecosystems, acyl lipids are initially hydrolyzed by microbial lipases with the release of free fatty acids. Glycerol, galactose, choline, and other non-fatty acid components released during hydrolysis are fermented to volatile fatty acids by the fermentative bacteria.

Anaerobic Formate and Hydrogen Metabolism

EcoSal Plus, 2004
During fermentative growth, Escherichia coli degrades carbohydrates via the glycolytic route into two pyruvate molecules. Pyruvate can be reduced to lactate or nonoxidatively cleaved by pyruvate formate lyase into acetyl-coenzyme A (acetyl-CoA) and formate.

Safe anaerobic metabolism

Science, 2017
Physiology Naked mole-rats live in large colonies deep underground in hypoxic conditions. Park et al. found that these animals fuel anaerobic glycolysis with fructose by a rewired pathway that avoids tissue damage (see the Perspective by Storz and McClelland).

Metabolic End-products of Anaerobic Spermatozoan Metabolism

Nature, 1966
DURING anaerobic fructolysis by mammalian spermatozoa, fructose is reportedly metabolized by way of glycolysis to lactic acid1,2. Results from many anaerobic metabolic investigations in our laboratory, however, in which bovine spermatozoa were incubated for 4 h at 37° C have consistently yielded low lactic acid values in relation to the fructose ...

Aerobic and anaerobic metabolism in Entamoeba histolytica

Experimental Parasitology, 1971
Abstract Respiration by Entamoeba histolylica is confirmed. A doubling of the rate of oxygen uptake was observed upon the addition of d -glucose to cells in which the glycogen reserve had been partially depleted. In cells metabolizing endogenous substrates the rate of oxygen uptake was not influenced by sodium cyanide or sodium succinate.

Anaerobic metabolism of cyclohexanol by denitrifying bacteria

Archives of Microbiology, 1988
Three strains of denitrifying bacteria were anaerobically enriched and isolated from oxic or anoxic habitats with cyclohexanol or cyclohexanone as sole electron donor and carbon source and with nitrate as electron acceptor. The bacteria were facultatively anaerobic, Gram-negative and metabolism was strictly oxidative with molecular oxygen, nitrate, or ...

Anaerobic Metabolism in Spiders

Physiological Zoology, 1983
The major anaerobic by-product of spiders is D-(–)-lactic acid. Minor accumulations of L-glycerol-3-phosphate may account for about 5% of the anaerobic ATP production. The possibility remains for other pathways, especially one that results in the accumulation of alanine and succinate.
