    • An object of the present invention is to provide a method for producing an amino acid-rich yeast which contains free amino acid in a high concentration. The present invention provides a method for producing an amino acid-rich yeast, which includes liquid-culturing a yeast in a stationary phase of proliferation under the condition that the pH of a liquid medium is equal to or higher than 7.5 and lower than 11; a method for producing an amino acid-rich yeast, which includes adjusting the pH of a liquid medium of the yeast in a stationary phase of proliferation to equal to or higher than 7.5 and lower than 11, and further culturing the yeast in the above pH range; a method for producing an amino acid-rich yeast, wherein the yeast is Saccharomyces cerevisiae or Candida utilis; an amino acid-rich yeast obtained by any one of the above methods for producing an amino acid-rich yeast; the amino acid-rich yeast extract wherein the amount of a free amino acid is from 7.5 to 18.0% by weight per dry yeast cell; and an amino acid-rich yeast extract extracted from the above amino acid-rich yeast.
    • 本发明的目的是提供一种含有高浓度游离氨基酸的富含氨基酸的酵母的方法。 本发明提供一种富含氨基酸的酵母的制造方法,其特征在于,在液体介质的pH等于或高于7.5且低于11的条件下,在增殖的固定相中液体培养酵母; 一种富含氨基酸的酵母的制造方法,其特征在于,将所述酵母的液体培养基的pH值调节至7.5以上且低于11倍,进一步培养上述pH值的酵母 范围; 一种生产富含氨基酸的酵母的方法,其中酵母是酿酒酵母或产朊假丝酵母; 通过上述任一种制备富含氨基酸的酵母的方法获得的富含氨基酸的酵母; 富含氨基酸的酵母提取物,其中游离氨基酸的量为每干酵母细胞7.5至18.0重量%; 和从上述富含氨基酸的酵母提取的富含氨基酸的酵母提取物。
