Liquid culture medium applicable to various edible fungi

Abstract

The invention relates to a liquid culture medium applicable to various edible fungi. The liquid culture medium comprises the following raw materials: 0. 3 to 0. 8 percent of honey, 0. 13 to 0. 16 percent of peptone, 0. 1 percent of monopotassium phosphate, 0. 025 percent of magnesium sulfate, 0. 5 percent of potato leachate, 0. 1 percent of wheat bran and the balance of rice soup. Due to the implementation of the liquid culture medium, nutrient ingredients in the culture medium are improved; fungi grow quickly; proper viscosity of the culture medium is guaranteed; liquid fungi can be distributed uniformly in the culture medium; and the implanting quality when the liquid fungi are implanted into a material bag is guaranteed.

Description

Technical field [0001] The invention involves a liquid medium for edible fungi, mainly a liquid medium that is suitable for a variety of edible fungi. Background technique [0002] For the current edible bacteria liquid bacteria medium, the formula components of the culture base (according to weight) are usually: 1.5 ‰ of protein cymbal, 1 ‰ potassium dihydrogen phosphate, magnesium sulfate of 1.25 ‰, and 5%potato leaching liquid.1%wheat bran, 2%sucrose.The manufacturing process includes the following steps: heating the water to 90 ° C to 95 ° C, put in wheat bran and potato leaching solution until dissolved; then add sucrose and protein crickets in turn, and stir up until dissolved;Magnesium, fully mixing into a mixed solution; the above mixture is high -temperature and high -pressure sterilization. [0003] There are the following deficiencies in this kind of technology: the germination of the liquid bacteria obtained in this way, usually 48-100 hours after vaccination, long ge...

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
