Functional bifidobacterium culture medium

Abstract

The invention discloses a functional bifidobacterium culture medium. The functional bifidobacterium culture medium comprises 4.5-5.5 g / l of peptone, 4.5-5.5 g / l of beef extracts, 9.5-10.5 g / l of tryptone, 4.5-5.5 g / l of yeast extract powder, 9.5-10.5 g / l of glucose, 0.8-1.0 ml / l of tween-80, 1.5-2.5 g / l of K<2>HPO<4>, 4.5-5.5 g / l of sodium acetate, 1.5-2.5 g / l of ammonium citrate dibasic, 0.20-0.30 g / l of Z<n>SO<4> 7H<2>O, 0.05-0.15 g / l of MgSO<4> 7H<2>O, 0.5% fructo-oligosaccharide and 1% CaCO<3>. The functional bifidobacterium culture medium has the advantages that the volumes of culture containers can be effectively reduced, the production cycle can be shortened, the production cost can be lowered, and the functional bifidobacterium culture medium has important practical value on developing and utilizing bifidobacterium.

Description

technical field [0001] The invention relates to the field of biological technology, in particular to a functional bifidobacteria culture medium. Background technique [0002] Bifidobacteria are important physiological beneficial bacteria in human and animal intestines. The reported physiological functions of Bifidobacteria include: adjusting intestinal flora, preventing constipation, reducing the incidence of colon cancer, producing antibiotics, and enhancing the immune system , Improve protein and vitamin metabolism, relieve lactose intolerance, treat liver damage, anti-tumor, lower cholesterol, etc. With the continuous accumulation of beneficial research results of bifidobacteria and the continuous improvement of modern people's requirements for a healthy diet, there is an upsurge in the research and development of bifidobacteria-containing foods, health products, and medicines at home and abroad. [0003] Bifidobacteria are obligate anaerobic bacteria, very sensitive to ...
