Probiotic flora culture medium containing added epimedium extract

Abstract

The invention relates to the microorganism filed, in particular to a probiotic flora culture medium containing added epimedium extract. The culture medium comprises the following components in percentage by weight: 0.1% of agar, 0.1% of beef extract, 0.25% of yeast extract powder, 3.5% of sucrose, 0.15% of defoamer, 0.1% of peptone and 2-5% of epimedium extract. The invention is characterized in that the basic medium of the probiotic flora is determined according to different animals and the difference of growth phases thereof, and 2-5% of the epimedium extract is simultaneously added; the probiotic flora stably grows and has no strain denaturation in the epimedium extract culture medium, maintains no change of ingredients of bacterial metabolins, has no strain denaturation, and causes good growth of compound microorganisms while having physiological active functions of the epimedium extract.

Description

technical field [0001] The invention relates to the field of microorganisms, in particular to a culture medium for probiotics added with epimedium extract. Background technique [0002] The existing application of compound microbial culture medium mostly adopts the culture medium suitable for the compound bacteria of the same type and the same genus with similar or similar components. This medium has a wide range of applications, weak selectivity, and easy cultivation of the same type of bacteria. The disadvantage of difficult growth of different types of bacteria. At present, many people have been studying the plant polysaccharide medium, but they have stayed on the research of a single bacterial group, and there is no plant polysaccharide medium suitable for the growth of complex microorganisms. Most of the plant active polysaccharides are extracts of Chinese herbal medicines. Most of the Chinese herbal medicines have an inhibitory effect on bacteria, and adding them to t...

[0002] The existing application of compound microbial culture medium mostly adopts the culture medium suitable for the compound bacteria of the same type and the same genus with similar or similar components. This medium has a wide range of applications, weak selectivity, and easy cultivation of the same type of bacteria. Disadvantages of difficult growth of different types of bacteria

At present, many people have been studying the plant polysaccharide medium, but they stayed on the study of a single bacterial group, and there is no plant polysaccharide medium suitable for the growth of complex microorganisms.

Most of the plant active polysaccharides are extracts of Chinese herbal medicines. Most of the Chinese herbal medicines have an inhibitory effect on bacteria, and adding them to the medium will inhibit the growth of bacteria. inconvenient
