A heat shock was applied to Saccharomyces cerevisiae: a change from 18 degrees C to 45 degrees C over 5 min and then maintenance at later temperature for 20 min followed by cooling to 18 degrees C. Such a treated inoculum, when used in an alcoholic fermentation of Welsch Riesling grape must at 18 degrees C, gave up to 12 g glycerol l(-1 )This is a new and easy method for high glycerol production in large scale wine production.
在5分钟内从18℃升温至45℃,然后在该温度下维持20分钟,随后冷却至18℃。将这种经过处理的接种物用于18℃下威尔士雷司令葡萄汁的酒精发酵时,甘油产量可达12 g·L⁻¹。这是一种在大规模葡萄酒生产中高产甘油的新的简便方法。
