S ummary : Glycerol stimulated sporulation of Saccharomyces cerevisiae Hanson, especially when the cells were precultured in a complex growth medium instead of a chemically defined medium. Optimum spore yields occurred with 1–4% of glycerol but some were produced in 16% glycerol. Sporulation in glycerol was much less sensitive to ammonium sulphate inhibition than it was in acetate. Growth occurred with glycerol as sole carbon source and glutamic acid as sole nitrogen source, but not with ammonium sulphate as the sole nitrogen source.
