It is generally accepted since PAsteur's studies of fermentation (1876) that a yeast, at least one capable of degrading sugars along a fermentative as well as a respiratory pathway, will make use of the energy provided by fermentative dissimilation when respiration is stopped by lack of oxygen.

The induction of lethal events and cytoplasmic "petite" mutations in random and synchronously dividing cultures of haploid and diploid cells of Saccharomyces cerevisiae was determined after treatment with 8-Methoxypsoralen plus 365 nm light. Diploid cells were always more resistant than haploid cel
In the petite positive yeast, Saccharomyces cerevisiae, cycloheximide selectively inhibits protein synthesis on cytoplasmic ribosomes, and, as a consequence, nuclear DNA synthesis. Mitochondrial DNA, however, is synthesized for d~6 h after cessation of protein synthesis. In this paper we show that i
