Journal of the Society of Brewing, Japan | 1987

Study on formation of high concentration of alcohol in Awamori mash.

Hisayasu Nakata; Satoshi Ishikawa; Hideo Gushiken; Masaru Hosaka

清酒酵母, 泡盛酵母, 焼酎酵母を使用した泡盛もろみは, 16.0%以上の高濃度のアルコールを生成する。清酒酵母, 泡盛酵母および焼酎酵母の間には発酵力に大きく違いはなく, 泡盛こうじの耐酸性α-アミラーゼの寄与が大きいことを確認した。一方, 清酒こうじのα-アミラーゼは, 耐酸性がなく, 清酒こうじを使用してクエン酸および乳酸を添加したもろみでは, 高濃度アルコ-ル生成株を使用してもα-アミラーゼが失活し, 糖化を阻害されるため, 10-13%のアルロールしか生成されなかった。


Journal of the Society of Brewing, Japan | 1987

Characters of yeasts isolated from Kokuto-shochu mashes.

Hisayasu Nakata; Masaru Hosaka; Takashi Sakai

Kokuto-shochu yeasts were classified into four groups by the method described in J. Ferment. Techno., 63, 509, 1985.


Journal of the Society of Brewing, Japan | 1986

Taxonomic characters of yeast isolated from soil around the Awamori distilleries by the enrichment culture method.

Masaru Hosaka; Hisayasu Nakata; Kenji Shinzato; Takashi Sakai

泡盛工場周辺の土壌から集積培養方法により, 50株のSaccharomyces属を分離し, それらの分類学的諸性質を調べたところ, これらの酵母は, 1980年から1981年11に泡盛工場内から分離した酵母と性質を異にし, 竹田らの分離した酵母と同じ性質であった。


Journal of the Society of Brewing, Japan | 1985

Taxonomic study on Shochu yeasts.

Hisayasu Nakata; Hiroaki Kuroki; Yoshimasa Taniguchi; Masaru Hosaka; Takashi Sakai

1981年に分離した焼酌酵母は, ビタミン欠培地で増殖し (164/164), クエン酸及びクエン酸カリウム無添加ビタミン欠培地で増殖せず (145小164), K-欠培地で増殖し (138/164), 清酒もろみ中で高泡の形成能を有さず (164/164), 吸収血清 (5) により凝集し (117/164), 1980から1981年に分離した泡盛酵母と明らかに区別できる。
