摘要
啤酒酵母原生质体融合株GR8的中试表明:融合株GR8凝絮性较强(本斯值为3.0);以12oBx麦芽汁为培养基,用500L发酵罐在12℃下发酵15d,发酵度为69.6%;发酵液中的双乙酰、乙醛、总高级醇、乙酸乙酯和乙酸异戊酯的含量分别为0.0390mg/L,3.26mg/L,84.7mg/L,11.14mg/L和0.99mg/L。
The pilot scale experiment ofprotoplast fusion strain GR8 of beer yeast indicated that GR8 has strong flocculation capability (bums value as 3.0) ; 12°Bx wort used as culture medium and 15 d fermentation at 12 ℃ in 500 L fermentor with fermenting degree as 69.6 %; the contents ofdiacetyl, aldehyde, total higher alcohols, ethyl acetate and isoamyl acetate in fermenting liquid were 0.0390 mg/L, 3.26 mg/L, 84.7 mg/L, 11.14 mg/L and 0.99 mg/L respectively.
