Respiratory pathways and oxygen toxicity in Phanerochaete chrysosporium.
Phanerochaete chrysosporium maintained on glucose as the carbon source contained severely impaired mitochondria that were characterised by the loss of both succinate dehydrogenase and cytochrome oxidase activities. These cells maintained a constant value for energy charge using anaerobic metabolism. Cells with these properties express lignin peroxidase when supplied with a pure oxygen atmospher...
متن کاملOxygen Toxicity
Prolonged exposure to oxygen at high pressure can have toxic effects, particularly on the central nervous system,but at pressures used clinically it does not pose a problem. The main topics discussed hereare:
متن کاملOxygen Toxicity.
Oxygen, the gas vital to sustain life, can also destroy it. It may become toxic at an elevated partial pressure, which may be the result of a rise in inspired oxygen concentration, an increase in environmental pressure or a combination of both. The toxicity tends to express itself most recognizably in one of several forms including central nervous system manifestations, pulmonary signs and symp...
متن کاملCNS oxygen toxicity.
This short manuscript will briefly present our current knowledge about CNS oxygen toxicity: the clinical manifestations, descriptions and incidence of symptoms, and the time – duration relationship that defines the safety limits and risk factors leading to enhanced toxicity to hyperbaric oxygen. A very general outline will present suggested mechanisms underlying hyperoxia-induced seizures and s...
متن کاملCO2 exacerbates oxygen toxicity
Reactive oxygen species (ROS) are harmful because they can oxidize biological macromolecules. We show here that atmospheric CO(2) (concentration range studied: 40-1,000 p.p.m.) increases death rates due to H(2)O(2) stress in Escherichia coli in a dose-specific manner. This effect is correlated with an increase in H(2)O(2)-induced mutagenesis and, as shown by 8-oxo-guanine determinations in cell...
