The Antarctic fungal strain Aspergillus glaucus 363 produces cold-active (CA) Cu/Zn-superoxide dismutase (SOD). The strain contains at least one gene encoding Cu/Zn-SOD that exhibited high homology with the corresponding gene of other Aspergillus spe

To evaluate the concept of metabolic cold adaptation in Antarctic fungi, we compared the activities of several key enzymes of the glycolytic pathway and the TCA cycle (hexokinase, glucose-6-phosphate dehydrogenase, glyceraldehyde-3-phosphate dehydrog

To extend the knowledge about the relationship between heat shock and oxidative stress in lower eukaryotes, the filamentous fungus Aspergillus niger 26 was chosen as a model system. Here, the response of A. niger cells to heat shock is reported. The
