✦ Synopsis

The spectral distributions of the luminescences emitted by the respiratory-deficient mutant of Saccharomyces cerevisiae and the normal yeast have been determined during the exponential phase of growth and during the stationary phase. The respiratory-deficient mutant gave a more intense emission in the visible region than did the normal yeast, but the UV intensities from the two yeasts did not differ greatly. These differences were explained in terms of higher O2- concentrations in the respiratory-deficient mutant which lead to enhanced visible region chemiluminescence from lipid peroxidation reactions.
