    • Provided is a method for producing a yeast containing glutamic acid at a high concentration. In the method for culturing a yeast, a yeast in a stationary growth phase is subjected to liquid culture under the conditions that the pH of a liquid medium is 7.5 or higher and lower than 11. After the pH of the liquid medium for the yeast in a stationary growth phase is adjusted to 7.5 or higher and lower than 11, the yeast is further cultured, whereby a yeast with a high glutamic acid content can be produced. In the invention, as the yeast, Saccharomyces cerevisiae or Candida utilis can be used. Therefore, by using the yeast with a high glutamic acid content obtained by the above-said method and the extract obtained by extraction from the yeast, a seasoning composition and a food or drink with a high glutamic acid content can be provided.
    • 提供一种高浓度含有谷氨酸的酵母的制造方法。 在培养酵母的方法中,将静止生长期的酵母在液体培养基的pH为7.5以上且小于11的条件下进行液体培养。在培养基中添加酵母的液体培养基的pH 通过将静止生长期调整为7.5以上且低于11,进一步培养酵母,由此能够制造谷氨酸含量高的酵母。 在本发明中,作为酵母,可以使用酿酒酵母或产朊假丝酵母。 因此,通过使用通过上述方法获得的谷氨酸含量高的酵母和从酵母中提取得到的提取物,可以提供具有高谷氨酸含量的调味组合物和食物或饮料。
