Abstract

The invention relates to the field of biological engineering, in particular to a culture medium and a preparation method of the culture medium. The formula of the culture medium for a yellow flammulina liquid strain comprises raw materials and an aqueous solution, wherein the raw materials comprise the following components in percentage by weight: 1.5-2.5 percent of white granulated sugar, 0.2-0.5 percent of soy bean meal, 0.1-0.3 percent of deactivated yeast powder, 0.05-0.1 percent of magnesium sulfate and 0.05-0.1 percent of monopotassium phosphate. The preparation method of the culture medium for the yellow flammulina liquid strain comprises the steps of culture medium configuration, adjusting, sterilizing, inoculating and culturing. Due to the adoption of the technical scheme, after the culture medium for the yellow flammulina liquid strain, which is disclosed by the invention, is used, yellow flammulina mycelia have high growth speed, strong activity and high mycelium content; and the inoculated strain has the advantages of high germination rate, short fermentation period and high rate of finished products.

Description

technical field [0001] The invention relates to the field of bioengineering, in particular to a culture medium and a preparation method thereof. Background technique [0002] Flammulina velutipes has the advantages of tenderness, tenderness, softness, pleasant taste, high protein content, etc. It is one of the world's famous edible fungi. The strains used in the production of Flammulina velutipes include solid strains and liquid strains. Compared with solid strains, liquid strains have the advantages of low cost, fast growth, and high biotransformation rate, which is the trend of technological innovation in the development of edible fungus industry. The liquid strain mainly depends on absorbing the nutrients of the liquid medium to grow. At present, the existing liquid culture medium and preparation method of Flammulina velutipes have shortcomings such as low preparation success rate, unsuitable mycelia growth, high technical requirements for operation, lack of versatility,...
