    • The present invention relates to a process for producing a 2-alkyl-2-cycloalken-1-one represented by the following general formula (2), including the step of reacting a 2-alkylidene cycloalkanone in the presence of a palladium and/or platinum catalyst which is treated in the following steps (a) and (b); and a method for activating the palladium and/or platinum catalyst including the following steps (a) and (b): Step (a): activating the palladium and/or platinum catalyst in an atmosphere containing a hydrogen gas; and Step (b): replacing the hydrogen gas being present as the atmosphere for the catalyst in the step (a), with an inert gas to remove the hydrogen gas out of the reaction system, wherein m is 0 to 3; n is 1 or 2; R1 and R2 are each independently a hydrogen atom or an alkyl group having 1 to 8 carbon atoms; and R3 is an alkyl group having 1 to 5 carbon atoms. In accordance with the present invention, the 2-alkyl-2-cycloalken-1-one can be produced with a high purity and a high productivity.
    • 本发明涉及一种由以下通式(2)表示的2-烷基-2-环烯烃-1-酮的制备方法,包括使2-亚烷基环烷酮在钯和/或 铂催化剂,其在以下步骤(a)和(b)中处理; 以及包括以下步骤(a)和(b)活化钯和/或铂催化剂的方法:步骤(a):在包含氢气的气氛中活化钯和/或铂催化剂; 和步骤(b):用惰性气体代替在步骤(a)中作为催化剂的气氛存在的氢气,以将氢气从反应体系中除去,其中m为0-3; n为1或2; R 1和R 2各自独立地为氢原子或具有1至8个碳原子的烷基; R3为碳原子数为1〜5的烷基。 根据本发明,可以以高纯度和高生产率制备2-烷基-2-环烯烃-1-酮。

    • A bakers' yeast strain characterized by having an isobutyric acid content in dry cells of 150 ppm or less and showing a very weak offensive taste and odor characteristic of yeast. This yeast strain is obtained through sexual reproduction between a monoploid yeast strain obtained by germinating spores of a diploid bakers' yeast strain which may be freeze-tolerant and another monoploid yeast strain obtained by germinating spores of a diploid alcohol or wiled-type yeast strain whose offensive taste and odor characteristic of yeast is weak, followed by screening the resulting yeast strains to select those having a weak offensive taste and odor characteristic of yeast and, if necessary, being freeze-tolerant.
