Abstract
Nagai, Susumu
(National Women's University, Nara, Japan). Differential reduction of tellurite by growing colonies of normal yeast and respiration-deficient mutants. J. Bacteriol.
90:
220–222. 1965.—A differential reduction of sodium tellurite was observed between normal and respiration-deficient mutant colonies of several species of
Saccharomyces
. Normal colonies turned black in contrast to mutant colonies which remained nearly white when grown on an agar medium containing 30 to 40 mg per liter of tellurite. Schopfer's medium enriched with yeast extract and a mixture of vitamins was most suitable to develop such black-and-white contrast. The difference was far less obvious when the asparagine of this medium was replaced by other nitrogen sources such as glutamate, peptone, or Casamino Acids. Addition of ammonium sulfate to the medium weakened and sometimes completely reversed the contrast. The usefulness of tellurite medium for diagnostic color differentiation of respiration deficiency was considered.
