Problems solved by technology

Natural medium is good for the growth of microorganisms, the disadvantage is that the composition is complex and inconsistent, and fungi are prone to spores on natural medium
At present, the medium used for the production of edible fungus liquid strains is mostly made of natural raw materials such as potatoes, bran, corn flour, soybean meal or soybean flour, such as the edible mushrooms disclosed in Chinese patent documents CN 106831037 A, CN 106497798 A, CN 107805096 A, etc. Bacteria liquid culture medium is prepared from raw materials such as potatoes, corn flour, wheat bran, soybean flour, soybean meal, yeast powder, peptone, etc. Although the medium made of such raw materials can ensure the growth of bacteria, the disadvantage is that the process Complex raw materials often require pretreatment, and second, often due to different batch sources of natural raw materials, the composition, pH and other properties of the medium will change, which will affect the stability and uniformity of the strain and further affect the consistency of later cultivation management.

Abstract

The invention relates to a precise fermentation culture medium for edible fungus liquid strains and application. The medium comprises a carbon source with monotonous components, a nitrogen source withmonotonous components, glycerin, KH2PO4, K2HPO4, MgSO4.7H2O, FeSO4, gibberellin, sodium diacetate, VB1, VB2 and GPE. The inventor of the medium discovers for the first time that the precise culture medium can be obtained by blending all kinds of compounds clear in component, and is suitable for growth of edible fungus mycelia, which overcomes the technical prejudice, that edible fungi need to becultured through a culture medium prepared from natural components, of technicians in the field. Since the components of the culture medium are controllable, mycelium growth speed is uniform after theliquid strains of different batches obtained through culturing are inoculated in solid compost, and production management is easily standard and programmable; the new conception is provided for reducing fluctuations in industrialized production of the edible fungi.

Description

technical field [0001] The invention relates to a precision culture medium for edible fungus liquid strains and its application, in particular to a liquid culture medium for industrialized cultivation of edible fungi and its preparation method and application, belonging to the technical field of edible fungi cultivation. Background technique [0002] The industrialized cultivation of edible fungi is the industrial production mode with the most modern agricultural characteristics, and it is the only way for the future development of the edible fungus industry. Special production strains are the basis of factory production and are directly related to the output, quality and benefit of the final product. At present, the industrialized seed production industry in the world has embarked on the road of specialization and industrialized mass production. Liquid strains have become the development trend of the edible fungus seed production industry because of their short culture tim...
