Abstract

The invention discloses a universal edible fungus liquid fungus culture medium.Its weight ratio of the formula is: malt dextrin 45-55 portions, dextrose 10-15 portions, cane sugar 10-15 portions, yeast extract paste 1-1.5 portions, peptone 1-1.5 portions, potassium di-hydrogen phosphate 2-3 portions, bitter salt 1-1.5 portions, and water 1000 portions. The invention also discloses the technology that includes following steps: heating water to 90-95 degree centigrade, adding malt dextrin and whisking until fully solving, adding dextrose, cane sugar, yeast extract paste, and peptone and whisking until fully solving, adding potassium di-hydrogen phosphate and bitter salt and fully mixing to make mixture liquid, which would take high temperature and high pressure sterilization. The invention has strong versatility and short fermentation period.

Description

technical field [0001] The invention relates to a culture medium and a manufacturing process thereof, in particular to a general-purpose edible mushroom liquid strain culture medium and a manufacturing process thereof. Background technique [0002] Culture medium is the basis for the quality of liquid strains. Whether the composition and ratio of the culture medium is appropriate or not has a great influence on the fermentation process of the liquid strain. Only by choosing reasonable culture ingredients and proportions can we quickly cultivate robust mycelium. Stable fermentation of liquid strains is necessary for intensive production, and its premise is a stable medium. The stability of the medium must have standard raw material quality components and standardized formulas, as well as standardized proportioning procedures. The current edible fungus liquid culture medium generally needs boiled potato juice or bran juice as raw materials, resulting in cumbersome procedure...
