Abstract

The invention relates to the technical field of probiotic mediums, especially to a probiotics medium and a culture method and application thereof. When the probiotics medium is a liquid medium, each 1L of the medium contains 10-12 g of lactalbumin hydrolysate, 5-6 g of yeast powder, 10-12 g of proteose peptone, 10-12 g of glucose, 3-5 g of sodium chloride, 180-200 ml of tomato juice, 1-2 ml of microscale salting liquid, and the rest of distilled water. When the probiotics medium is a solid medium, the medium also comprises 18-20 g of agar. The invention has the following beneficial effects: carbon nitrogen ratio is complete; vitamins and trace elements are complete; by the use of the medium, all probiotics can grow well; cost of the medium is low; operation is convenient; the medium is suitable for mass production; and problems existing in the prior art can be solved economically and effectively.

Description

technical field [0001] The invention relates to the technical field of beneficial bacteria culture medium, in particular to the beneficial bacteria culture medium and its cultivation method and application. Background technique [0002] In today's world, human beings have realized that the imbalance of micro-ecology can bring about the danger of disease, and have recognized the potential harm to the human body caused by antibiotics, hormones, chemicals and pesticide residues in food. In order to prevent diseases, improve human health, reduce environmental pollution and competitive pressure, human beings need to return to nature and call for green food and medicine. Probiotics and antimicrobial peptide products are emerging in fields such as health care, medicine, food, cosmetics, feed, and environmental protection. More and more countries oppose the use of antibiotics as growth promoters and pass legislation to ban them. Alternatives to antibiotics have become a hot topic ...
