Method for solid liquid mixed culture of medical hericium erinaceus mycelia

Abstract

The invention discloses a method for solid liquid mixed culture of medical hericium erinaceus mycelia. According to the method, special medical white hericium erinaceus strains cultured from wild hericium erinaceus in Zhongtiao mountain primeval forest through optimization for many years are adopted. Compared with the ordinary edible hericium erinaceus, the mycelia produced from the strains have the advantages that polysaccharides and peptide are contained, five kinds of anticancer substances, seven kinds of vitamins, three kinds of active cellulase, 18 kinds of amino acids, human body necessary trace elements and the like are also contained, the contents of cystine, histidine and arginine with great medical values are high, the amino acids are identified for 6 to 7 points, and the protein content is 16.65 percent, and is respectively 3 times and 1.8 times that of other hericium erinaceus.

Description

technical field [0001] The invention relates to the technical field of microorganism cultivation, in particular to a method for cultivating medicinal Hericium erinaceus mycelium. Background technique [0002] Hericium erinaceus is named because its fruiting body resembles the head of a little monkey. It is a rare edible fungus with both edible and medicinal value. It is flat in nature and sweet in taste. Cancer, treatment of neurasthenia, for the treatment of digestive system diseases and tumors such as indigestion, gastric ulcer, esophageal cancer, gastric cancer, duodenal cancer, and spout cancer. At present, Hericium erinaceus has been successfully used in existing products, such as the marketed Hericium Jianweiling Capsules, in which Hericium erinaceus is the main ingredient of the product. [0003] At present, there are mainly three kinds of production approaches of Hericium erinaceus: 1. Artificial cultivation, the advantage is that it is simple and easy to implement,...

Problems solved by technology

[0003] At present, there are mainly three kinds of production approaches of Hericium erinaceus: 1. Artificial cultivation, the advantage is that it is simple and easy to implement, and the cost is low; the disadvantage is that the cultivation period is long, about 3 months; 2, solid fermentation, cultivate Hericium erinaceus bacteria with solid medium Silk, to obtain secondary metabolites, its advantages are: the medium is simple and widely sourced, and the price is cheap; the fermentation process generally does not require strict aseptic operation; the oxygen supply and temperature during the cultivation process can be controlled by direct air forced ventilation; The treatment of fermentation residue is simple, and it can be directly used as feed or fertilizer; the disadvantages are: the water activity of the medium is low, the medium is uneven and difficult to stir, the growth of bacteria, the absorption of nutrients and the secretion of metabolites are uneven, making The monitoring and control of fermentation parameters is difficult, so continuous operation and automation are difficult; the temperature control of the heat generated by microbial respiration and metabolism is very difficult; the use of solid-state culture is mostly based on empirical data and operating experience, and it is easy to contaminate miscellaneous bacteria; 3. Liquid deep layer Fermentation to obtain the best operating conditions to produce a large amount of mycelium and metabolites in a short period of time. The advantages are: industrial continuous production can be carried out, a wide range of sources of culture raw materials, the best culture conditions can be achieved by controlling the fermentation device, and the cycle is short. Efficiency High; the disadvantage is that the production of mycelium is low, and it is difficult to form a large-scale application
