Abstract
Summary
Mitochondria from two strains of Aspergillus niger were examined for succinate-cytochrome c reductase, NADH cytochrome c reductase, cytochrome c oxidase, succinoxidase, and NADH oxidase activities, and for phosphate-acceptor control. Except for NADH-cytochrome c reductase, each of these activities was considerably higher in the nitroaryl-resistant strain than in the wild type. These data supplied further evidence of augmented mitochondrial function in the resistant strain which aids in explaining metabolic differences between the two. Although intact Aspergillus mitochondria oxidize exogenous NADH, this activity did not appear to be coupled to phosphorylation.
