Summary: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 atmosphere, which may reflect a response to accumulating reactive oxygen species. Cells maintained on cellulose retained fully functional mitochondria, but expressed lignin peroxidase without being exposed to a pure oxygen atmosphere. In the cells maintained on cellulose, mitochondrial function may be limited by the supply of glucose, leading to the accumulation of reactive oxygen species.
