Liquid culture medium applicable to various edible fungi

Abstract

A liquid culture medium suitable for a variety of edible fungi, its raw materials include: 0.3-0.8% honey, 1.3-1.6‰ peptone, 1‰ potassium dihydrogen phosphate, 0.25‰ magnesium sulfate, 5% potato extract, 1% wheat bran, and the rest are rice soup. By implementing the present invention, the nutritional components in the culture medium are improved, and the strains grow quickly. Uniform distribution ensures the quality of implantation when liquid bacteria are implanted into the bag.

Description

technical field [0001] The invention relates to a liquid culture medium for edible fungi, in particular to a liquid culture medium suitable for various edible fungi. Background technique [0002] Present edible fungus liquid culture culture medium, the formula component (by weight) of its culture medium is usually: the peptone of 1.5 ‰, the potassium dihydrogen phosphate of 1 ‰, the magnesium sulfate of 1.25 ‰, the potato extract of 5%, 1% wheat bran, 2% sucrose. The manufacturing process includes the following steps: heating water to 90°C to 95°C, adding wheat bran and potato extract and stirring until dissolved; then adding sucrose and peptone in turn, stirring until dissolved; adding potassium dihydrogen phosphate, sulfuric acid in turn Magnesium, fully mixed to make a mixed solution; the above mixed solution is sterilized under high temperature and high pressure. [0003] Such technology has the following disadvantages: the liquid strains obtained in this way germinate...

Problems solved by technology

[0003] Such technology has the following disadvantages: the liquid strains obtained in this way germinate slowly, usually germinate in 48-100 hours after inoculation, and the germination time is long, which is easy to infect assorted bacteria and reduces the survival rate of edible fungi; The final strains are unevenly distributed in the liquid medium, so that it is difficult to ensure the quality of implantation when the liquid strains are planted into the material bag, and the survival rate of edible fungi in the material bag is low
