Abstract: The present invention provides yeast belonging to the genus Saccharomyces which generates, in dough containing 5% sugar, carbon dioxide gas in an amount of not less than 2.0 ml per g of the dough and not less than 1.20 ml per ml of volume expansion of the dough at 38° C. in 60 minutes; a method of screening for the yeast; bread dough containing the yeast; a process for making bread using the yeast; and bread having an anti-mold effect which is obtained by the process.

Abstract: The present invention provides an yeast capable of making bread excellent in flavor and taste and weak in fermentation smell, a dough containing the yeast, a process for making bread using the yeast or the dough and the bread made by the method. The present invention relates to the yeast which belongs to the genus Saccharomyces and generates 35 ppm or less of isoamyl alcohol, a ratio of 2 or less of isoamyl alcohol to isobutyl alcohol, 1.5 ppm or more of diacetyl in the bread and 2 ml or more of carbon dioxide gas per 1 g of the dough, a screening method for selecting the yeast, a process for making bread containing the yeast and the dough and bread made by the method.
