Abstract

The invention relates to the biological engineering field, in particular to a culture medium and a preparation method thereof. The Pleurotus eryngii liquid strain culture medium comprises raw materials and an aqueous solution. The raw materials comprise the following components by weight percent: 1.5%-2.5% of white granulated sugar, 0.1%-0.3% of soybean meal powder, 0.1%-0.3% of yeast extract, 0.05%-0.1% of potassium dihydrogen phosphate and 0.05%-0.1% of magnesium sulfate. The preparation method of the Pleurotus eryngii liquid strain culture medium comprises the following steps: preparing a culture medium, adjusting, sterilizing and performing inoculation and culture. By adopting the technical scheme, after the product is used as the culture medium of the Pleurotus eryngii liquid strain, the Pleurotus eryngii mycelium has high growth velocity, strong vitality and high mycelium content; and the inoculated strain has high germination rate, short fermentation period and high yield.

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] Pleurotus eryngii has the advantages of thick flesh and crisp texture, especially its dense, firm and milky stipe tissue, which can be eaten entirely, and the stipe is more crispy and refreshing than the cap, so it is called "king of oyster mushrooms". , "Dried Scallop Mushroom", which has almond fragrance and abalone taste, is suitable for fresh-keeping and processing, and is deeply loved by people. [0003] The strains used in the production of Pleurotus eryngii 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 fungi industry. The liquid strain mainly depends on absorbing the nutrients of the liquid medium to gro...
