Novel culture medium good for increasing yield of lactic acid bacteria

Abstract

The invention discloses a novel culture medium good for increasing yield of lactic acid bacteria. The medium comprises 0.30-0.40 g / l of ZnSO4.7H2O, 0.10-0.18 g / l of MgSO4.7H2O, 5.0-5.5 g / l of peptone, 5.0-6.0 g / l of beef extract, 10.0-11.0 g / l of tryptone, 5.0-6.0 g / l of yeast extract powder, 10.0-12.0 g / l of glucose, 1.0-1.5 ml / l of tween 80, 1.5-2.5 g / l of K2HPO4, 4.5-5.5 g / l of sodium acetate, 1.5-2.5 g / l of diammonium hydrogen citrate, 0.5% of fructooligosaccharide, and 1% of CaCO3. The novel culture medium is capable of increasing the yield of lactic acid bacteria, the problems such as preparation complexity and low viable count can be effectively solved, the viable count is increased, stable production can be achieved, and the yield can be increased.

Description

technical field [0001] The invention relates to the technical field of biological culture medium, and specifically refers to a novel culture medium that is beneficial to improving the yield of lactic acid bacteria. Background technique [0002] Lactic acid bacteria are important physiological beneficial bacteria in human and animal intestines. The reported physiological functions of lactic acid bacteria include: adjusting intestinal flora, preventing constipation, reducing the incidence of colon cancer, producing antibiotics, enhancing the immune system, increasing protein and Vitamin metabolism, alleviating lactose intolerance, treating liver damage, anti-tumor, lowering cholesterol, etc. With the continuous accumulation of beneficial research results on lactic acid bacteria and the continuous improvement of modern people's requirements for healthy diet, there is an upsurge of research and development of food, health care products and medicines containing lactic acid bacter...

AI Technical Summary

Problems solved by technology

The new culture medium is a kind of lactic acid bacteria, which can effectively solve the problems of tedious preparation of the culture medium of lactic acid bacteria and low number of viable bacteria. While increasing the number of viable bacteria, the new culture medium can realize stable production and increase yield
