摘要: 研究了耐氧双歧杆菌在GAM和PTYG培养基中生长曲线、基质消耗曲线和代谢产物。结果表明,耐氧双歧杆菌培养12h菌数分别达8.4×109cfu/ml和7.2×109cfu/ml;pH由7.6降至4.2培养(培养20h);对糖和蛋白质的消耗率分别为56.4%~56.8%和58.8%~60.0%,代谢产物中乙酸∶乳酸的克分子数为33∶2.08~4.17。

Abstract: The process of cell growth and metabolism of oxygen-resistant Bifidobacterium in two different kinds of media(GAM medium and PTYG medium)were studied.The high consuming ratio of oxygen-resistant Bifidobacterium was determined.The living oxygen-resistant Bifidobacterium number was 8.4×109 cfu/ml after fermentation 12h 37℃ and the pH of ending point of the fermentation was ≤4.2.The cumulation of lactitic acid higher than acetic acid.
