摘要
对19种双歧杆菌进行了以低聚果糖(FOS)为碳水化合物源生长的筛选。几种动物源菌株(嗜热芽孢杆菌、最小芽孢杆菌和cuniculi芽孢杆菌)对菊粉的聚合度(DP)•†15)明显优于人源菌株。这些菌株在不同来源的菊粉上生长得同样好，但不能代谢levan，一种ƒÀ(2-6)- d -果糖的聚合物。含有大量低分子量(DP<5)碳水化合物的FOS制剂获得最佳生长。在菊粉上生长最好的菌株需要这种FOS的存在才能最大限度地诱导外链菊粉酶。这些结果表明，动物双歧杆菌菌株可以与短链FOS一起作为动物饲料的补充。
Characterization of Growth and Inulinase Production by Bifidobacterium spp. on Fructooligosaccharides
A total of 19 species of Bifidobacterium were screened for the ability to grow with fructooligosaccharides (FOS) as the carbohydrate source. Several strains of animal origin (B. thermophilum, B. minimum, and B. cuniculi) grew significantly better than strains from human source on inulin (degree of polymerization (DP) •† 15). These strains grew equally well on inulin from several sources, but were unable to metabolize levan, a polymer of ƒÀ(2-6)-D-fructose. Best growth was obtained on FOS preparations containing a significant proportion of low-molecular-weight (DP<5) carbohydrates. Strains which grew best on inulin required the presence of this FOS for maximal induction of the exo-inulinase. These results suggest that animal strains of bifidobacteria may be used in conjunction with short-chain FOS as a supplement to animal feed.
