目的:研究菊芋在体外对双歧杆菌生长的影响,为进一步开发菊芋资源和生产双歧杆菌制品提供理论依据。方法:以菊芋汁为试验材料,以长双歧杆菌(Blm)和两歧双歧杆菌(Bbm)为试验菌株,采用Hungate厌氧培养技术。结果:菊芋汁在基础培养基中对双歧杆菌具有促进生长作用,表现为生长速率提高,最大生长量增加,并且对不同菌种的促进生长作用存在差异。结论:菊芋在体外对双歧杆菌有促进生长作用。 Objective: To study the effect of Jerusalem artichoke on the growth of Bifidobacterium in vitro and to provide a theoretical basis for the further development of Jerusalem artichoke resources and the production of Bifidobacterium. Methods: Jerusalem artichoke juice was used as test material, Bifidobacterium longum (Bm) and Bm (Bbm) as test strains, and Hungate anaerobic culture was used. Results: Jerusalem artichoke juice could promote the growth of bifidobacteria in the basal medium, which showed that the growth rate was increased, the maximum growth was increased, and the growth promotion effects of different strains were different. Conclusion: Jerusalem artichoke can promote the growth of Bifidobacterium in vitro.
