We examined the formation of iso-butyl alcohol in fermented synthetic media by industrial yeasts. The formation of iso-butyl alcohol by awamori yeasts isolated in 1980-1981 was the same as other industrial yeasts in fermented media using _L-valine as the nitrogen source. But the formation of iso-butyl alcohol by awamori yeasts isolated in 1980-1981 was about twice that of other industrial yeasts in fermented media using ammonium sulfate as nitrogen source. Therefore, the A/B (iso-amyl alcohol/iso-buryl alcohol) ratios of these yeasts were less than 2.49. The awamori yeasts isolated in 1980-1981 were distinguishable from other industrial yeasts by this aroma quality in the fermented medium using ammonium sulfate as the nitrogen source.
