Abstract

The invention discloses a composite culture medium for lactobacillus ferment and preparing method thereof. The culture medium contains 8-70% of licorice root filtered juice. In the culture medium, adding 7-25 g polypeptone in per 1000 ml licorice root filtered juice, also can add 2.0-5.0 g liver infusion. The selected 3 kinds of lactobacillus growing well in the culture medium has better effect than traditional lactobacillus selected culture medium-MRS culture medium. The formula of this culture medium is simple and needs simple preparing method, culture condition is easily controlled, low cost, safety and harmless, can be used widely for researching, developing and producing one of the most important probiotics-lactobacillus.

Description

technical field [0001] The invention relates to the technical field of production of medicines, food and food additives, veterinary medicine, biological feed and feed additives, in particular to a compound medium for lactobacillus fermentation and a preparation method thereof. Background technique [0002] Lactobacillus (Lactobacillus) is an important physiological bacteria and an important member of the normal flora in the intestinal tract of humans and other mammals. Since the physiological regulation of Lactobacillus and its fermentation products has been confirmed by long-term application practice and subsequent scientific research, the application range of Lactobacillus and its products in the fields of pharmaceuticals, food, veterinary medicine and feed production is constantly expanding, becoming these An important production strain in the industrial field; in recent years, due to its probiotic characteristics, structural characteristics and genetic characteristics, i...
