摘要
对酿酒酵母S2.101的最适生长条件进行了研究,结果表明,S2.101对高粱、小麦糖化液的发酵力强,对玉米、大米糖化液也有较强的发酵作用;在液体酵母合成培养基中加入50%的麸皮培养基能促进S2.101的生长;S2.101的最适生长时间为28h、最适生长温度为30℃、最适生长pH值为6.0。
The optimum growth conditions ofsaccharomyces cerevisiae strain S2.101 were studied, The results showed that S2.101 presented the strongest fermenting power in sorghum saccharifying solution and wheat saccharifying solution and it also presented strong fermenting power in corn saccharifying solution and rice saccharifying solution, the addition of 50 % bran in liquid yeast synthesis culture medium could advance the growth of S2.101, the optimum growth time of S2.101 was 28 h, the optimum growth temperature of S2.101 was at 30 ℃, and the optimum growth pH of S2.101 was 6.0.
