Problems solved by technology

Most of the current micro-enriched medicinal bacteria liquid fermentation formulas use beef extract, egg white or common yeast powder as nitrogen sources, and sucrose, glucose or rice as the main carbon source. The content of active components such as exopolysaccharides, medicinal bacteriocins, and medicinal bacteriolic acids in the liquid is not high, and the production cost increases
In fact, in the liquid myceliu

Embodiment Construction

[0020] 1) Yeast fermentation liquid concentrate: select the market-supplied yeast fermentation liquid concentrate;

[0021] 2) Preparation of carbon source component raw materials: mix rice, wheat, and corn stalk powder according to the mass ratio: 1:1:2, grind to 50-100 mesh, and set aside;

[0022] 3) Preparation of trace elements: chromium, magnesium, zinc and selenium are mixed according to the mass ratio of 10:10:3:3.

[0023] 4) The formula of the liquid fermentation medium for micro-enriched medicinal bacteria is (each component is a mass percentage): yeast fermentation liquid concentrate 3.0-4.5%, carbon source component raw material 3.0-4.0%, KH 2 PO 4 0.1-0.3%, vitamin B 1 0.01-0.03%, and finally add distilled water to make up to 100%, adjust the pH to 6.0-7.0, sterilize at 121°C for 15-20min, after cooling, add medicinal fungus seed liquid for fermentation.

Abstract

The invention provides a manufacturing method of a liquid fermentation medium of a trace element-rich medicinal fungus, a liquid mycelium fermentation medium formula of the trace element-rich medicinal fungus is designed and prepared as follows: a yeast fermentation liquid concentrate is used as a main nitrogen source, a mixture of rice, wheat and corn straw powder is used as a main carbon source, and at the same time four trace elements comprising chromium, magnesium, zinc and selenium are added. A yeast fermentation liquid is effectively recycled, the nitrogen source cost is greatly reduced, the trace elements in the mediumare transformed into organic trace element forms after fermentation and transformation, and can be used as trace element supplements.

Description

technical field [0001] The invention relates to a method for preparing a medium formula for liquid fermentation of medicinal bacteria, in particular to a method for preparing a liquid fermentation medium for micro-enriched medicinal bacteria, which belongs to the technical field of biopharmaceutical production. Background technique [0002] In a broad sense, medicinal fungi refer to all fungi that can be used for medicine, and in a narrow sense, they refer to large fungi (mushrooms) used in medicine. There are Cordyceps sinensis, cicadae, Leiwan, Anluopisan, etc. in the wild; at present, there are Ganoderma lucidum, Poria, Polyporus, Gastrodia elata, Phellinus, fungus, Yunzhi, etc. cultivated. These medicinal fungi have been used for thousands of years in our country. Although they have different effects, the biggest advantage is that they have no toxic side effects. Modern medical research shows that they not only have the traditional functions of nourishing qi, strengthen...
