葡萄酒酿酒菌种的保藏方法

本文介绍了酿酒菌种常用的保藏方法，酵母菌的短期保藏可采用橡皮塞代替棉塞的斜面试管或液体试管保藏法，长期保藏可采用液体石蜡保藏法，乳酸菌的短期保藏可用液体试管和穿刺培养保藏法，长期保藏可用旋塞试管保藏法，但长期有效的保藏菌种还是以真空冷冻干燥保藏法最行。

The Preservation of Wine-making Microorganism

Common preservation methods of winemaking microorganisms were introduced in this paper, Itshowed that yeast could be preserved in a short time by using slant-face-tube or liquid-culture-medium-tubemethods with rubber-cork instead of cotton-cork, and liquid-olefin methods could be used for long preserva-tion Liquid-culture-medium-tube and stab-culture method could be used to preserve lactic acid bacteria in ashort time, and longer preservation could be realised by using spiral tube methods. But the most effectivemethod to conserve microoganisms for a long time is the vacuum freeze-drying.
